PRESS RELEASE

Eni will focus its activities in Portugal on the gas sector, increasing its participation in Gas de Portugal to 49%.

Eni: agreement for the reorganisation of the gas sector signed with the Portuguese Government, EDP and REN

Eni, representatives of the Portuguese government, Electricidade de Portugal (EDP), Galpenergia, Parpublica and Red Electrica National (REN) signed in Lisbon the final agreements for the reorganisation of the company Galpenergia as part of the process underway to reorganise the Portuguese energy sector. The signing follows the preliminary agreement signed on 6 February 2004 by the Minister of the Economy, Carlos Tavares, the Minister of Finance, Manuela Ferreira Leite, and Eni’s Chief Executive Officer, Vittorio Mincato.

Under these agreements Eni will focus its activities in Portugal in the gas sector through a 49% shareholding in Gas de Portugal (currently owned indirectly through Galpenergia, in which Eni has a shareholding of 33.34%), and will exit from the refining and marketing sector of oil products.

Gas de Portugal will be owned jointly by Eni, EDP and REN, for an initial maximum period of 18 months; that is, from the date of transfer of the shares of Gas de Portugal and the separation and transfer to REN of the natural gas transport network in Portugal.

Gas de Portugal will subsequently be owned by Eni with a 49% shareholding and EDP with 51% with agreements that will ensure the joint management of GDP and the cooperation among partners.

The entire transaction involves a balance in cash which will be collected by Eni of 667 million euro.

The execution of the agreement is subject to the approval of the competent competition Authorities.

The agreements signed confirm Eni’s commitment for the cooperation of Eni in Portugal and reinforce the growth strategy in the gas sector abroad. Gas de Portugal has regasification capacity (around 5 billion cubic metres per year) at its Sines terminal in Portugal, the nearest entry point for the liquefied gas arriving from Nigeria and transport capacity (currently 3 billion euro per year) through the Trans-Maghreb gasline from Algeria. Eni’s petroleum products will continue to be distributed throughout the Iberian peninsula through Agip Espaňa.

To the Shareholders:

the appointment of PricewaterhouseCoopers S.p.A. as Independent Auditors approved by the shareholders’ meeting held on June 1, 2001 will expire on the date of the shareholders’ meeting called to approve Eni S.p.A. Financial Statements at December 31, 2003.

The Board, on the basis of the selection of the offers presented by four different audit firms and in compliance with the current legislation, as the Board of Statutory Auditors has issued a positive evaluation on the proposal, proposes to the approval of the shareholders’ meeting the appointment of PricewaterhouseCoopers S.p.A. as Independent Auditors for the audit of Eni S.p.A. and Eni consolidated Financial Statements, the audit of the regularity of the accounting procedures applied by the Company and for the limited review of Eni half-year Report for the years 2004, 2005 and 2006. Further, as Eni shares are listed also on the New York Stock Exchange (NYSE), the Board proposes to commit to PricewaterhouseCoopers S.p.A., for the same period, the audit of the accounting data released in the U.S.A. to comply with SEC Regulations (“Form 20-F”) and of the accounting adjustments consequent to the application of U.S GAAP and the release of the audit report in English set forth in compliance with US GAAS.

The Board has selected the offer of PricewaterhouseCoopers S.p.A. on a qualitative and economic basis because of the specific technical experience of the firm in the audit of oil & gas international companies financial statements.

PriceWaterhouseCoopers’ offer includes other 262 Eni subsidiaries and total fees of euro 6.7 million (corresponding to 120,243 hours).
The Board of Directors of the following listed companies: Saipem, Snam Rete Gas and Società Azionaria per la Condotta di Acque Potabili will also propose to the respective Shareholders’ Meeting the offers presented by PriceWaterhouseCoopers approved autonomously by those Boards. Consequently it will be appointed Independent Auditor for these companies and their subsidiaries.

PriceWaterhouseCoopers will also execute supplemental audit activities according to the terms and conditions set forth by Document no. 600 of the Italian Audit Principles; therefore PriceWaterhouseCoopers will assume the full responsibility of the audit executed by the minor audit firms appointed by Eni subsidiaries (representing about 2% of

##### Table of Contents

total activities and revenues of Eni Group). Consequently, PriceWaterhouseCoopers will assume in Eni Consolidated Financial Statements Audit, the role and responsibility of Sole Independent Auditor of Eni Group.

To the Shareholders:

You are invited to approve the proposal of the Board of Directors to appoint PricewaterhouseCoopers S.p.A. as Independent Auditors for the three-year period 2004-2006 for:

- |  | the audit, to be executed in the course of the financial year, of the regularity of the accounting procedures applied by the Company and of the correct accounting representation of the business activities, pursuant to Article 155 of Legislative Decree dated February 24, 1998 No. 58;
- |  | the limited review of Eni half-year Report, pursuant to Consob Communication No. 97001574 dated February 20, 1997;

Eni

With a market capitalization amounting to over euro 65 billion as of April 20, 2004, Eni is one of the most important integrated energy companies in the world which operates in the oil and gas industry, power generation and oilfield services, construction and engineering. In these businesses it has a strong edge and leading international market positions.

STRATEGIES

n Develop core business activities; in particular: maintain strong hydrocarbon production growth by internal lines while continuing portfolio rationalization and focusing on reserve replacement

Expand sales on European markets and maintain sale levels in Italy, leveraging on the increase in demand and the expansion of power generation capacity; complete the restructuring of the Italian fuel distribution network and develop in selected areas in Europe; increase the efficiency and flexibility of the refining system

n Pursue the integration of core activities in order to support Eni’s international growth and improve its competitive position

n Continue to focus on core business

n Intensify efficiency and efficacy improvement programs

n Maximize return for shareholders by selecting capital expenditure and maintaining strict financial discipline

Eni intends to maintain strong hydrocarbon production growth by developing on internal lines and continuing its program of rationalisation of its asset portfolio aimed at increasing its value by focusing on strategic areas with sound growth potential and leaving marginal ones. Special attention will be paid to reserve replacement in order to support long-term growth.

In gas activities Eni intends to expand sales on European markets and to maintain sale levels in Italy leveraging on expected natural gas demand growth, the development of integrated gas-electricity supply and the completion in time of the plan of expansion of power generation capacity in its industrial sites. Key growth targets set for 2007 are the following: (i) daily hydrocarbon production of about 1.9 million boe corresponding to a 5% average annual increase in the 2003-2007 period (net of the effects of portfolio rationalization); (ii) the sale of 44 billion cubic meters of gas in European markets; (iii) the reaching of an installed power generation capacity of about 5.3 gigawatts by 2006.

In downstream oil Eni intends to complete the upgrading of its distribution network in Italy and develop/consolidate its presence in selected areas in Europe where it can leverage on operating synergies and a well established brand. In refining Eni will continue to pursue high levels of efficiency and flexibility and the development of high quality fuels anticipating the environmental requirements of new European regulations. In oilfield services, construction and engineering activities Eni intends to concentrate its presence in the strategic segment of large projects for the development of offshore hydrocarbon reserves and construction of industrial plants and infrastructure based on the application of technologies for hydrocarbon production, treatment and transmission and natural gas and heavy crudes upgrading.

Eni intends to reduce capital employed in non core businesses and to pursue the integration among its core activities in order to support international growth by means of integrated projects and to improve its competitive positioning. Eni will continue to improve operational efficiency and efficacy targeting cost savings of about euro 3.4 billion at 2006 (over 65% of which already achieved in the 1999-2003 period).

Strong attention will be devoted to R&D, the key factor for the future development of the oil industry. Financial resources dedicated to this activity will be increased significantly; in addition, expenditure will be more and more focused on those strategic projects through which Eni can achieve competitive advantages in the medium to long-term, in particular in the areas of exploration and recovery of hydrocarbons and of upgrading of heavy crudes and natural gas.

Eni intends to pursue its growth strategy by implementing a four year capital expenditure plan of euro 25.5 billion, about 90% of which will be concentrated in the Exploration & Production, Gas & Power and Refining & Marketing segments. Cash flow from operations will allow to satisfy financial requirements related to new capital expenditure and the payment of dividends, assuming an average Brent price of 16 dollars/barrel in the 2004-2007 period in real terms (base year 2000) and a dollar/euro exchange rate at parity.

integration

Eni’s business portfolio is characterized by a strong vertical integration, which guarantees greater stability in short-term results and allows for efficient long-term planning.

This advantage is essential in the uncertain scenario of international oil prices and reduces the impact of price volatility on Eni’s results.

n Continue to pursue efficiency improvement

Eni operates in the exploration and production of hydrocarbons in Italy, North Africa, West Africa, the North Sea and the Gulf of Mexico. It also operates in areas with great exploration and production potential such as the Caspian Sea, Australia, the Middle and Far East and Latin America. In 2003, Eni produced 1,562,000 boe per day and, at December 31, 2003, it reached estimated proved reserves of 7,272 million boe. Eni is pursuing an aggressive production growth strategy aimed at achieving a daily production target of about 1.9 million boe by 2007, which corresponds to an average annual growth rate of 5% over the next four years. Production growth will be pursued by developing in areas where Eni has a consolidated presence and through the start-up of important projects in Libya, Angola, Nigeria, Iran and Kazakhstan. Eni intends to continue the rationalization of its asset portfolio, started after the purchase of British-Borneo and Lasmo, in order to increase its value by focusing on strategic areas with the highest growth potential and leaving marginal areas with limited development prospects. Exploration efforts will be selected by concentrating in areas with high mineral potential. In 2003, beside the successful continuation of exploration activities in the northern Caspian Sea, Eni made interesting discoveries in Italy, Angola, Nigeria, the North Sea, Indonesia, Algeria, Tunisia, Pakistan and the Gulf of Mexico.

Eni will continue to improve its performance by searching for operating solutions with lower operating costs and synergies.

MAIN RESULTS

In 2003 hydrocarbon production reached the record level of 1.56 million boe/day with a 6.1% increase. Eni intends to maintain a strong production growth in the near future leveraging on the development of assets in portfolio and targeting about 1.9 million boe/day in 2007, equal to an annual average growth rate of 5%

Eni’s proved hydrocarbon reserves reached 7,272 million boe with a replacement rate of 142% (118% excluding the effects of purchase and sale of property). In the medium term production growth and reserve replacement will be supported by the relevant mineral potential of Eni’s assets located in core areas of North and West Africa with the contribution of new fields in Australasia and higher oil production in Italy. The average reserve life index was 12.7 years

Among the major start-ups of 2003 are: the Abo oil field (Eni operator with a 50.19% interest) offshore Nigeria; the Balal (Eni’s interest 38.25%) and Darquain (Eni operator with a 60% interest) oil fields in Iran; the Woollybutt oil field (Eni operator with a 65% interest) offshore Australia; the Bhit (Eni operator with a 40% interest) and Sawan (Eni’s interest 23.68%) gas fields in Pakistan; the Ourhoud (Eni’s interest 4.59%) and ROM Est (Eni operator with a 50% interest) oil fields in Algeria; the gas and condensate Mikkel field (Eni’s interest 14.9%) offshore Norway; the Medusa gas field (Eni’s interest 25%) in the Gulf of Mexico; the Xikomba oil field (Eni’s interest 20%) offshore Angola

Within the North Caspian Sea PSA (Eni is single operator with a 16.67% interest) the importance of the Kashagan oil field discovery in the Kazakh offshore of the Caspian Sea was confirmed by the appraisal activities performed in the area. The field’s recoverable reserves, estimated at 13 billion barrels by employing gas reinjection techniques, make Kashagan the world’s most relevant oil discovery of the past thirty years. Production is expected to start in 2008. Appraisal activities of the field and the survey of the area under contract continued successfully in 2003 with the drilling of the fourth and fifth commitment wells out of six wells planned. At the beginning of the winter work on the sixth and last commitment well, which already reached its final depth, was suspended and is going to be completed in the first half of 2004

In Saudi Arabia, an exploration licence for the extraction of natural gas in the so called C area covering about 52,000 square kilometers in the Rub al Khali basin at the border with Qatar and the United Arab Emirates was awarded to a consortium formed by Eni with an international oil company and Saudi Aramco (Eni operator with a 50% interest). The project marks Eni’s return to upstream activities in this country where it had operated in the early 1970s

In Kazakhstan, within the development of the Karachaganak field (Eni co-operator with a 32.5% interest), a condensate treatment plant (Karachaganak Processing Complex - KPC) with a 150,000 barrels/day capacity and transmission infrastructure for the export of liquids produced to western markets were started-up. The latter consist mainly of a 635-kilometer long pipeline with a 24 inch diameter linking the Karachaganak field to Atyrau, point of connection with the Caspian Pipeline Consortium pipeline in which Eni holds transportation rights up to 65,000 barrels/day. In 2004, these new production facilities and transmission infrastructure will lead to an increase in Eni’s share of daily production of liquids to about 65,000 boe

In Libya, the joint development (Eni’s interest 50%) of the natural gas, oil and condensate fields of

Wafa, located in onshore permit NC-169 A and Bahr Essalam, located in the NC-41 offshore permit, with recoverable reserves amounting to approximately 950 million boe net to Eni, is underway. Within the onshore development, over 80% of the planned development wells were drilled: within the offshore development, the Sabratha platform and its infrastructure as well as the Mellitah treatment plant are under construction. The Wafa field is expected to start production in the fourth quarter of 2004 at an initial level of 65,000 boe/day net to Eni. The Bahr Essalam field is expected to start production in June 2005 at an initial level of 61,000 boe/day net to Eni

In Angola in Block 15 (Eni’s interest 20%) development activities of the A and B phases continued in the Kizomba area. Phase A is finalized to starting production at the Hungo and Chocalho fields with recoverable reserves of 1 billion barrels (145 million net to Eni). Production is expected to start in the second half of 2004. Peak production of 39,000 boe/day net to Eni is expected in 2006. In phase B, concerning the development and start-up of production of the Kissanje and Dikanza fields, with recoverable reserves of 910 million barrels (141 million barrels net to Eni), four EPC contracts were awarded for the completion of the project. Production start-up is scheduled for 2006

Eni was awarded five exploration licences: (i)two in Egypt as operator, Ras el Ush and South Ferain located in the Gulf of Suez (Eni’s interests 75 and 70%, respectively); (ii) two in Norway in Blocks 34/12 and 35/10 (Eni’s interest 60%) and in Block 31/4 East of Brage (Eni’s interest 12.26%); (iii) one in Pakistan as operator (Eni’s interest 92.5%) in Block 2667-6 located in the provinces of Dadu and Balochistan. Eni is waiting for the Egyptian Parliament to confirm the conferral of licences in Blocks 24 and 26 Offshore Mediterranean and Block 10 Western Desert

A total of 105 new exploratory wells were drilled (43 of which represented Eni’s share). Overall success rate was 46.7% (45.7% representing Eni’s share)

Streamlining measures and synergies obtained through the integration of purchased companies allowed for cost reductions amounting to about euro 240 million

Italy

In 2003, Eni’s hydrocarbon production in Italy totaled 300,000 boe/day and represented 19% of Eni’s total production. Eni’s exploration and development interests in Italy are concentrated in the Po Valley, the Adriatic Sea, the Central Southern Apennines, Sicily and the Sicilian offshore. Natural gas production totaled 216,000 boe/day and represented approximately 72% of Eni’s hydrocarbon production in Italy. Eni’s principal natural gas fields are located in the Adriatic Sea (Barbara, Porto Garibaldi/Agostino, Angela/Angelina, Cervia/Arianna and Porto Corsini Mare Ovest which collectively accounted for 43.5% of Eni’s natural gas production in Italy in 2003) and in the Ionian Sea (Luna, which accounted for 8.2%). In early 2005 the Tea, Arnica and Lavanda gas wells, located 60 kilometers off the Adriatic coast are expected to start production at the final level of 0.73 million cubic meters/day (about 5,000 boe/day) net to Eni.

Daily production of oil in Italy totaled 84,000 barrels. Eni’s three major fields, Val d’Agri in Southern Italy, Villafortuna in the Po Valley and Aquila in the southern Adriatic offshore, represented 73.6% of Eni’s total oil production in Italy in 2003. Other oil fields are Rospo in the Adriatic Sea, Vega offshore southern Sicily, Gela and Ragusa in Sicily.

In Val d’Agri development activities continued (see “Development Projects” below).

Within its portfolio rationalization process Eni defined the sale of the entire capital of Stargas SpA (Eni’s interest 100%), the company to which the assets in exploration and production of natural gas of Società Petrolifera Italiana pA (Eni’s interest 99%) were transferred. In 2003 Stargas production amounted to about 5,000 boe/day, consisting mainly of natural gas.

In the medium term, the achievement of full production of the Val d’Agri fields and the development initiatives in natural gas will partly offset declines of mature fields.

deviated to a collection platform in the EA field from which it will be sent to the Offshore Gas Gathering System (OGGS) pipeline that in turn will carry it to the Bonny liquefaction plant. 16 development wells have been drilled and completed, which confirmed the results of the forecast model. The construction of the FPSO and relevant topsides is underway. Recoverable reserves net to Eni amount to about 75 million barrels. Production is scheduled to begin in 2005 at a peak flow of about 20,000 barrels/day net to Eni. Eni’s share of the development expenditure amounts to over dollar 350 million.

Kazakhstan – North Caspian Sea

Eni is operator of the North Caspian Sea PSA (Eni’s interest 16.67%) in joint venture with seven international oil companies. In May the partners in the project, except for one, exercised their pre-emptive rights and purchased in proportional shares the interest of British Gas that left the project. A Sale and Purchase Agreement with effect from January 1, 2003 was agreed among the partners, subject to authorization by the Kazakh authorities. Under the agreement, Eni’s share in the project will go from 16.67% to 20.372%.

The area under contract is made up of 11 blocks covering a total of over 5,500 square kilometers at a water depth of 2 to 10 meters. This project, due to the mineral potential of existing structures and to the operating and technological challenges it poses, resulting from the shallow waters which are frozen for about six months a year, represents an extremely important industrial feat in the oil industry. Eni intends to apply the most advanced technologies and methods in order to provide maximum environmental protection to the North Caspian area. In this area in July 2000 the Kashagan field was discovered and subsequent appraisal allowed to define the amount of recoverable reserves of oil in the 7 to 9 billion barrels range, that could reach 13 billion barrels with gas reinjection techniques, thus making this field the most important discovery in the world in the past thirty years. On June 30, 2002 the Eni led consortium and the Kazakh authorities declared the saleability of the Kashagan field. At the end of 2002 the consortium presented a development plan for the field. At the end of June 2003 the front end engineering of the first development phase was completed. After the signing of a Supplemental Agreement and related deeds, on February 25, 2004 the development plan for Kashagan was approved. The plan, which will be implemented in multiple phases, aims at the production of the recoverable reserves up to 13 billion barrels through partial reinjection of gas and a total expenditure of 29 billion dollars (5 billion being Eni’s share). Production is expected to start in 2008 at a level of 75,000 barrels/day and to increase to 450,000 barrels/day at the end of the first development phase. Target production plateau is expected at 1.2 million barrels/day.

Iran – The South Pars Project phases 4 and 5

In 2000 Eni entered a buy-back contract with the National Iranian Oil Company (NIOC) for the development of Phases 4 and 5 of the South Pars gas and condensate field, an eastern extension of the North Field (Qatar), the largest natural gas field in the world in the offshore of the Persian Gulf. The project, in which Eni is operator with a 60% interest, involves the construction of two offshore platforms in waters of a depth of around 70 meters, the drilling of 24 production wells and the construction of two gas pipelines, each approximately 105-kilometer long, to connect the platforms to the onshore gas center to be built at Assaluyeh. The gas center will have a treatment capacity of 20 billion cubic meters/year and will be able to produce 47.6 million cubic meters/day of natural gas, one million tonnes/year of LPG and 80,000 barrels/day of condensates. Construction work is underway for completing the platforms and building the treatment plant, as well as drilling of development wells. Capital expenditure for the development of the project is estimated at about dollar 2 billion (Eni’s share dollar 1.4 billion) and will be incurred in the 2000-2005 period. Eni will act as operator for the development phase and will supply technologies, know-how and resources. The contract foresees that the production of liquids from the field over a period of 8 years will repay costs incurred and ensure return on capital employed. Recoverable reserves amount to 170 million boe net to Eni. Production is scheduled to begin in the last quarter of 2004 at an initial level of 8,000 boe/day net to Eni.

Australia – The Bayu Undan Integrated Project

The offshore Bayu Undan field (Eni’s interest 12.04%) is located in Block Zoca 91/12-13 in the international cooperation area between Australia and East Timor, about 500 kilometers north west of Darwin at a water depth of 80 meters.

The project includes two phases. The first one for the development of liquids(Propane butane and condensates) and the second one for the development of LNG. Phase 1, aimed at producing liquids by means of three drilling, production and treatment platforms, relevant facilities and an FPSO for the storage of liquids, has been completed. Production started in February 2004. The second phase entails the construction of a 26-inch diameter 500-kilometer long sealine that will link the field to Darwin where an onshore LNG plant with a 3.5 million tonnes/year capacity is under construction. The first LNG shipment is scheduled for the first quarter of 2006.

Under a 17-year long contract, gas produced will be sold to two Japanese companies, Tokyo Electric and Tokyo Gas, that bought a 10.08% interest in the integrated project.

Recoverable reserves amount to 434 million barrels of liquids and 79 billion cubic meters of natural gas (Eni’s total share is 88 million boe). Production is scheduled to peak at about 160,000 boe/day (18,000 net to Eni) in 2009. The total investment will be dollar 3.5 billion, of which 396 million is Eni’s share, of these 206 for the upstream portion.

Norway – Kristin Project

In the offshore oil and gas Kristin field (Eni’s interest 9%) located in the Haltenbanken area in the Norwegian Sea, the Norne and Aasgard fields are in production. The development plan foresees the drilling of 12 underwater wells, the installation of a semi-submersible platform with treatment facilities and the laying of a gas pipeline connecting it with the Aasgard Transport Pipeline, 10-kilometer off Kristin, and of a 20-kilometer long oil pipeline to carry condensates to the Aasgard C storage vessel. Recoverable reserves of this field amount to 527 million boe (48 million net to Eni). Production is scheduled to start in October 2005 with a production peak of 20,000 boe/day net to Eni expected in 2006. Eni’s expenditure in this project amounts to dollar 240 million.

STRATEGIES

n Develop natural gas sales in target markets

n Maintain volumes sold in Italy within regulatory limits leveraging on the integration of natural gas and electricity generation and on the expected increase in demand

n Implement effective marketing actions developing an integrated commercial supply of gas and electricity

n Develop the LNG segment in order to give value to available natural gas production volumes

natural gas

Eni operates in the supply, transmission, distribution and sale of natural gas. In 2003, Eni sold 71.5 billion cubic meters of natural gas (including volumes consumed in operations). Eni’s transmission network in Italy through medium and high pressure pipelines is about 30,000-kilometer long. Outside Italy Eni owns transportation rights on approximately 3,800 kilometers of pipelines.

Eni is pursuing the development of sales on European markets in order to compensate the lower growth opportunities on the domestic market, due to the limits imposed to operators by the sector regulations. In Italy, Eni intends to maintain sales volumes within the regulatory limits through the optimal allocation of supplies between direct sales in Italy and in the rest of Europe and by using natural gas at its own electricity generation plants and, at the same time, leveraging on the expected consumption growth, in particular for electricity generation. Eni’s marketing policy will tend to customer satisfaction by means of market segmentation, the development of commercial offers based on the gas-electricity integration and the expansion and customization of services offered to customers.

Outside Italy development will be focused on the European gas market, in particular in countries with interesting growth and profitability prospects (Iberian Peninsula, Turkey, Germany and Northern Europe) where Eni can make optimal use of its diversified portfolio of supply contracts and its extensive gas pipeline network which allows the supply of natural gas from several sources. Eni completed its entry into those markets by means of acquisitions and construction of infrastructure and, in 2003, it started the operational and commercial phase of this plan. Eni also intends to expand its presence in LNG in order to increase the value of the natural gas it produces in West and North Africa and the Far East. Based on contracts signed and actions defined, Eni expects to sell about 44 billion cubic meters of natural gas on European markets in 2007. Eni will also intensify its cost reduction actions especially in transmission activities in Italy and in secondary distribution.

MAIN RESULTS

In August the laying of the Greenstream underwater gasline, a new route for natural gas import into Italy, started. This infrastructure will link Mellitah on the Libyan coast to Gela in Sicily covering about 520 kilometers at a maximum depth of about 1,130 meters and when fully operational will carry 8 billion cubic meters/year (of which 4 billion net to Eni) of natural gas from the Libyan fields of Wafa and Bahr Essalam. Volumes available have been already booked under long term contracts and will allow a further opening of the Italian natural gas market. Laying is expected to be completed on September 30, 2004

Within its strategy of international expansion in natural gas in the Iberian Peninsula, Eni purchased 50% of Spanish company Unión Fenosa Gas with an expenditure of euro 442 million. Operating in all segments of the natural gas business and LNG, Unión Fenosa Gas is a relevant partner that can contribute to Eni’s reaching its objective of developing its presence on the Spanish natural gas market which shows interesting growth prospects. In Portugal Eni signed an agreement with the Portuguese Government for the reorganization of Galp Energia within the restructuring process of the Portuguese energy sector. Eni will concentrate in the natural gas sector through a 49% interest in Gas de Portugal and by exiting the segment of refining and marketing of refined products in Portugal where Eni operated through Galp Energia. This transaction entails cash proceeds of euro 667 million

In February supplies of natural gas from Russia to the Turkish national company Botas started via the Blue Stream underwater gasline across the Black Sea. In 2003 Botas withdrew 1.3 billion cubic meters (of which 0.6 billion were Eni’s share). Volumes transported and marketed will progressively increase in future years and are targeted to about 16 billion cubic meters per year (8 billion net to Eni) in 2010

Eni continued its program for developing its electricity generation capacity targeted at about 5.3 gigawatts of installed power by 2006 with total capital expenditure amounting to approximately euro 2.3 billion (of which 1.2 were already expensed). In 2003 the construction of combined cycle power stations fired with natural gas with installed capacity of 3.8 gigawatts at Eni’s sites in Brindisi, Ferrera Erbognone, Mantova and Ravenna started. The commercial start-up of other units under construction is expected by stages between 2004 and early 2006. When fully operational, volumes of natural gas destined to electricity generation will reach 6-7 billion cubic meters per year

Rationalizations and efficiency improvement actions generated cost savings of approximately euro 50 million

the Italian natural gas system

In the next decade world consumption of natural gas is expected to increase, due to the continuous improvement in technologies applicable to all phases of natural gas production, the higher environmental compatibility of natural gas as compared to other hydrocarbons, the expected demographic, economic and social developments and the steady increase in natural gas reserves. Europe represents one of the areas with the highest development rate, where the average increase in consumption is expected to be about 3% per year.

Given the recent regulatory and organizational developments, the Italian national natural gas system takes part in the structural change ongoing in Europe with the prospect of a single market for energy. In this context Italy will be able to make good use of its geographical position and its double integration with the European internal market and the Mediterranean area. Eni has the know-how and experience necessary for becoming a leader in this process of European development.

One of the new features of the development process ongoing in Europe is the importance acquired by international hubs, whose development can be attributed to the new regulations on third party access to transmission networks, to increased gas availability in markets and to the progressive cancellation of the territorial destination clause in supply contracts (see specific paragraph below). Hubs represent the major interconnection points in international transmission networks where volumes of natural gas are traded on spot markets and not under long term contracts. The development of European hubs, located in Great Britain, Belgium and Germany, represents an opportunity for Eni for selling increasing gas volumes, as Eni can take advantage from its diversified supply portfolio and the flexibility provided by long term contracts.

The demand for natural gas in Italy

With consumption amounting to about 77 billion cubic meters in 2003 (increasing by 9.4% over 2002) Italy is the third European market for natural gas after Great Britain and Germany. In 2003, about 20% of natural gas requirements were met through domestic production (including natural gas volumes withdrawn from storage), while imports covered 80%.

Eni expects natural gas consumption in Italy to reach about 90 billion cubic meters in 2010, corresponding to an annual average increase of about 2.5%. The share of natural gas on total domestic energy requirements is expected to reach nearly 37% as compared to the present 33%.

Most of this increase will concern natural gas used in electricity generation, because of the significant advantages of the use of natural gas in combined cycle plants, thanks to its lower investment cost, higher yields and reduced polluting emissions as compared to other fuels. Demand is expected to increase also from residential and commercial users, due to the further expansion of the natural gas distribution network in Southern Italy and the increased use of natural gas in residential space heating in households and services, in large tertiary firms and as vehicle fuel.

Transmission, dispatching and regasification

Transmission, dispatching and regasification activities in Italy are carried out by Snam Rete Gas, a company listed on the Italian Stock Exchange (in which Eni holds a 50.07% interest). Eni’s primary transmission network was conferred to Snam Rete Gas in July 2001 in implementation of Legislative Decree No. 164/2000 concerning the Italian natural gas market, which provides for the separation of transmission, dispatching and regasification activities from all other activities in the natural gas segment.

The Italian natural gas transmission system is made up of a national pipeline network and a regional pipeline network for a total length of 31,220 kilometers, of which 30,120 owned by Eni.

The Italian national transmission network is made up of high pressure trunklines, mainly with a large diameter, which carry natural gas from the entry points to the system – import lines, storage sites and main Italian natural gas fields – to the linking points with the regional transmission network. The national network includes also some interregional lines reaching important markets.

The regional transmission network is made up of the remaining lines and allows the transmission of natural gas to industries, power stations and local distribution companies of the various local areas served.

At December 31, 2003 the national pipeline network owned by Eni extended for 7,993 kilometers. Underground pipelines have a maximum diameter1 of 48 inches and carry natural gas at pressures of 24 to 75 bars. The underwater pipeline crossing the Messina Strait has a diameter of 20 to 26 inches and carries natural gas at a pressure equal to or higher than 115 bars.

The major pipelines interconnected with import trunklines that are part of Eni’s national network are:

for natural gas imported from Algeria:

• |  | two lines with a 48/42-inch diameter, each approximately 1,500-kilometer long, including the smaller pipes that cross underwater the Messina strait, which link Mazara del Vallo (on the Southern coast of Sicily) to Minerbio (near Bologna). These lines are linked to the import pipelines that carry natural gas from Algeria through the Sicily Channel. The pipeline transmission capacity amounts to 87 million cubic meters/day;

for natural gas imported from Russia:

• |  | two lines with 48/42/36/34-inch diameters extending for a total length of approximately 900 kilometers that are linked to the Austrian network in Tarvisio and cross the Po Valley reaching Sergnano (near Cremona) and Minerbio. The pipeline transmission capacity amounts to 84.4 million cubic meters/day;

for natural gas imported from the Netherlands and Norway:

• |  | two lines, with a 48-inch diameter, 177-kilometer long extending from the Italian border at Passo Gries (Verbania), point of connection with the Swiss network, to the node of Mortara, in the Po Valley. The pipeline transmission capacity amounts to 60.7 million cubic meters/day.

In 2003 Eni’s national network increased by 50 kilometers due to the entry into service of lines: (i) from Istrana to Camisano (37 kilometers); (ii) from Bernalda to Brindisi (7 kilometers); (iii) from Malborghetto to Bordano (6 kilometers).

The national transmission network will be upgraded by means of:

• |  | the laying of a third line with a 48-inch diameter over 264 kilometers (124 of which already operational as of December 2002) from Tarvisio to Zimella (Verona) on the pipeline carrying natural gas imported from Russia and the upgrade of the Malborghetto compression station. Works are expected to be completed by 2007;

(1) |  | The diameter of lines varies according to the route’s carrying requirements or according to their different construction or upgrading date.

n |  | the laying of a pipeline (66-kilometer long with a 36-inch diameter, 24 million cubic meters/day transmission capacity) from Gela (point of connection with the Greenstream pipeline importing gas from Libya. See international gaslines below) to Enna (point of interconnection with the national network). This pipeline is expected to start operations in 2004;

n |  | the laying a 70-kilometer long pipeline with a 30-inch diameter (39 already operating in 2003 and 31 from 2004) from Pontremoli to Parma for upgrading the connection of the Panigaglia LNG terminal with the national network and local markets.

Eni’s regional transmission network is made up of pipes with smaller diameter than the national lines for a total length 22,127 kilometers. These pipes carry natural gas at pressures lower than 5 bars, between 5 and 24 bars and between 24 and 75 bars. In 2003, Eni’s regional network increased by 275 kilometers due to the entry into service of the Sannicola-Ugento-Tricase pipeline in Southern Italy, of the connection with the EniPower Ferrera-Erbognone power station and of various connections to end users.

Eni’s system is completed by: (i) 11 compressor stations with a total power of about 620 megawatts; (ii) 4 marine terminals linking underwater pipelines with the on-land network at Mazara del Vallo and Messina in Sicily and Favazzina and Palmi in Calabria.

The control room of the dispatching system is located in San Donato Milanese and oversees and monitors the whole transmission network in cooperation with local units. In 2003 this system obtained the ISO 9000 certification. Peripheral units are represented by 8 districts that monitor the transmission network through 69 centers that guarantee operation, maintenance and control of the whole system. Each unit is responsible for operations in accordance with technical specifications and applicable laws and regulations. With the aim of rationalizing maintenance activities in 2003 various interventions were performed: (i) extension of remote control/remote monitoring by installing 74 new remote control units (valves, reduction plants and network terminals) which allow to reduce the time necessary for interventions aimed at restoring normal functioning and at increasing safety and reliability of operations; (ii) rationalization of local units and reduction of their number from 74 to 69; (iii) the entry into service on 90% of all maintenance units of a new IT system for the optimization of monitoring and periodic supervision; (iv) extension of new remote diagnostic systems of gas compressor units that allow for a constant monitoring of the system’s efficiency and for the optimization of costs and intervention times.

In addition to the international pipeline transmission system, natural gas enters Eni’s system also through the Panigaglia (Liguria) LNG terminal, which receives liquefied natural gas (LNG) carried by tanker ships. This terminal is the only one in Italy, at its maximum it can input approximately 3.5 billion cubic meters/year into the transmission network. LNG is downloaded from tanker ships and stored, then vaporized in a regasification plant made up of cryogenic pumps and submerged flame vaporizers. When it has recovered the gaseous state, natural gas is input in the transmission network. This terminal also regasifies LNG

bought by Enel. In 2003, volumes of LNG regasified amounted to the equivalent of approximately 3.5 billion cubic meters of natural gas. Upgrading of this terminal is underway by means of an enhancement of the boil-off gas recovery system.

In 2003 approximately 76.4 billion cubic meters of natural gas were input in the national network, of these approximately 33% were owned by third parties.

The Italian natural gas system is supplied for about 80% with imported gas, transmitted to Italy through a network of international high pressure pipelines for a total of about 3,800 kilometers; in which Eni owns transportation rights, in particular:

n |  | the TENP PIPELINE, 968-kilometer long (a 500-kilometer long single line and a 468-kilometer long doubling line) with transit capacity of 44 million cubic meters/day and four compression stations, transports natural gas from the Netherlands through Germany, from the German-Dutch border of Bocholtz to Wallbach at the German-Swiss border. In 2003 the upgrading of this pipeline was completed with the entry into service of 44 kilometers of doubling line and a 3.7 million cubic meters/day increase in transit capacity;

n |  | the TRANSITGAS PIPELINE, 291-kilometer long, with one compression station, which transports natural gas from the Netherlands and from Norway crossing Switzerland with its 165-kilometer long main line and a 71-kilometer long doubling line, from Wallbach where it joins the TENP pipeline to Passo Gries at the Italian border. It has a transit capacity of 61 million cubic meters/day. A new 55-kilometer long line from Rodersdorf at the French-Swiss border to Lostorf, an interconnection point with the line coming from Wallbach was built for the transport of Norwegian gas;

n |  | the TAG PIPELINE, 1,018-kilometer long, made up of two lines, each about 380-kilometer long and a third line 258-kilometer long, with a transit capacity of 81 million cubic meters/day and three compression stations, which transports natural gas from Russia across Austria from Baumgarten, the delivery point at the border of Austria and Slovakia, to Tarvisio, point of entry in Italy. This pipeline is being upgraded with the laying of a third 380-kilometer long line (258 already operating);

n |  | the TTPC PIPELINE, 742-kilometer long, made up of two lines each 371-kilometer long with a transit capacity of 78 million cubic meters/day and three compression stations, which

|  | transports natural gas from Algeria across Tunisia from Oued Saf Saf at the Algerian border to Cap Bon on the Mediterranean coast where it links with the TMPC pipeline;

n |  | the TMPC PIPELINE for the import of Algerian gas, 775-kilometer long, made up of five lines each 155-kilometer long with a transit capacity of 101 million cubic meters/day which crosses underwater the Sicily Channel from Cap Bon to Mazara del Vallo in Sicily, the point of entry into Italy.

In August 2003 works started for the laying of the Greenstream pipeline, an underwater 520-kilometer long pipeline with a 32-inch diameter for the transport of natural gas from Mellitah in Libya to Gela in Sicily for the transmission of natural gas from Libyan fields (targeted at 8 billion cubic meters/year, of which 4 billion is Eni’s share, with a transmission capacity of 24.4 million cubic meters/day, and laid at a maximum depth of 1,130 meters by the Saipem Castoro 6 vessel. This project is scheduled to be completed by September 30, 2004 with an expenditure of dollar 953 million, corresponding to euro 0.8 billion (dollar 715 million corresponding to euro 0.6 billion is Eni’s share) including the link to the national network.

At the end of 2002 the Blue Stream underwater pipeline started operating. This 774-kilometer long (on two 24-inch diameter lines) pipeline with a transmission capacity of 49 million cubic meters/day, linking the Russian and Turkish coast of the Black Sea, will transport approximately 16 billion cubic meters (Eni’s share 8 billion) of natural gas to be sold on the Turkish market (see “Development Projects” below). Supplies to the Turkish national company Botas started in February 2003.

Sales in Italy

In 2003, Eni’s natural gas sales in primary distribution in Italy amounted to 52.8 billion cubic meters (including volumes consumed in operations). The Italian natural gas market is made up of three main segments: residential and commercial, industrial and thermoelectric. Customers can be divided into two groups: final users directly consuming natural gas and wholesalers (mainly local distribution companies) purchasing natural gas to sell it to final customers (mainly small industries and residential and commercial users). According to the types of distribution, natural gas sales are divided into: (i) large distribution (primary distribution) which includes sales to wholesalers and large customers; (ii) local distribution (secondary distribution) represented almost exclusively by sales made by local distribution companies to commercial and residential customers, the tertiary sector and small industries located in urban areas, receiving natural gas from low pressure networks. From January 1, 2003 with the complete opening of the natural gas market, as per Legislative Decree No. 164/2000, all customers are allowed to purchase natural gas at any source and to enter contracts with transmission companies on the national network and with distribution companies on local networks for the transmission to the delivery points.

In 2003 wholesalers, including local distribution companies and automotive natural gas sellers, sold over 34 billion cubic meters to final users (44% of total natural gas consumption), with an 8% increase over 2002. In 2003, Eni’s natural gas sales to wholesalers amounted to 24.1 billion cubic meters.

Natural gas consumption in the industrial segment (linked to the national and regional networks) amounted to over 16 billion cubic meters (22% of total consumption), with a 1% increase over 2002. In 2003, Eni’s sales of natural gas to industrial users amounted to about 13 billion cubic meters (including volumes consumed in operations).

Natural gas consumption in the thermoelectric segment amounted to over 26 billion cubic meters (34% of total consumption), with a 17% increase over 2002. This segment includes electricity producers and distributors (Enel and some municipal utilities) and industrial

##### Table of Contents

producers of electricity. In 2003, Eni’s sales of natural gas to thermoelectric users amounted to 15.7 billion cubic meters (including volumes consumed in operations).

In 2002 Eni reorganized its activities by creating six new branches in Italy in order to react promptly and efficiently to market requirements and applying the home working model to all its sales personnel. The new marketing strategy is aimed at market segmentation and customer satisfaction, through offers tailored on customers needs and the integration of gas and electricity. In particular the customized commercial offer includes a range of elements such as, for example, various price formulas and types of indexes aimed at controlling price volatility, availability of services and technical assistance. In 2003 Eni’s commercial strategy was focused on contact channels: sales persons, contact centers, technical assistance, a new customer portal, which was completed in the year.

Eni, through its 100% subsidiary Italgas, is the Italian leader in the retail sale of natural gas to residential and commercial users with 5.8 million customers in 2003 (about a third of the market). In 2003, Eni’s retail sales in Italy amounted to 8.4 billion cubic meters (approximately 25% of the retail market). Eni owns a low pressure urban network in Italy consisting of 46,780 kilometers of pipelines at December 31, 2003, and serving 1,228 municipalities, among which Rome, Naples, Venice, Florence and Turin (the latter through an affiliate).

Sales activities and customer management are performed by Italgas Più SpA, established in 2002 by Italgas SpA in implementation of the regulations contained in Legislative Decree No. 164/2000, which provided for the separation of retail sales from all other activities in secondary distribution of natural gas; the new company was conferred the relevant business and is now present on the market with a new and wider supply of services; in particular:

n |  | a post-counter service for extraordinary and planned maintenance interventions on autonomous household heating systems, offered in two forms: (i) “Assistenza Italgas Più” concerning the planned maintenance of heaters fired with any fuel that need to be periodically monitored and subjected to combustion analysis; (ii) “Pronto Assistenza” concerning fast interventions of skilled technicians for repairing damages or checking heaters and other parts of the heating plant;
n |  | a service of energy management addressed mainly to the public administration, condominiums, the tertiary sector and industrial enterprises supplying heat instead of just natural gas, design of heating systems and consultancy services. It provides immediate solutions to problems of management, design and upgrade of plants and frees customers from technical and organizational tasks as wells as from responsibilities and administrative tasks.

Italgas Più also improved its tools for getting in contact with customers adding to the traditional access point other specific channels:

n |  | an integrated toll-free call center system (located in Turin, Rome, Florence, Naples, Chiavari) which customers can access for any information concerning services provided: payment of bills, information on consumption, requests for service and all technicalities related to it;
n |  | a network of franchisors made up of 94 “shops” with flexible opening hours available to customers for any request concerning services provided. Italgas Più targets the establishment of 460 franchised shops by 2005.

The interactive web site www.italgaspiu.it represents a true online shop where customers can: (i) find all information concerning services; (ii) check their accounts; (iii) simulate consumption; (iv) change personal data; (v) organize payments through their bank account. This business will be developed by entering new areas and by promoting new services such as air conditioning and co-generation for small enterprises, in order to foster new forms of consumption.

Sales in the rest of Europe

On European markets Eni signed seven long-term supply contracts with operators in the natural gas sector. These contracts, when fully operational, will enable Eni to supply about 15 billion cubic meters of natural gas per year, including 8 billion cubic meters (Eni’s share 4 billion) from the Libyan fields. Until the production from Libyan fields comes on stream, these supplies will be covered with gas derived from Eni’s wide and diversified portfolio of supply contracts.

In 2003 sales in Europe amounted to 25 billion cubic meters, including sales through affiliates (about 7.5 billion cubic meters); in particular: (i) about 14 billion related to sales in target markets, among which Turkey (0.6 billion to Botas), Germany and Northern Europe (a total of 6.2 billion), the Iberian Peninsula (3.2 billion, of which 1.1 billion to the Spanish electric company Iberdrola), Hungary (3.3 billion); (ii) over 9 billion related to supply contracts with operators in the natural gas sector in Italy.

Outside Italy Eni is present in natural gas secondary distribution in the rest of Europe and Latin America as follows:

n |  | Hungary through Tigaz (controlled by Eni with a 50% interest), the largest regional gas distribution company in the country. In 2003 Tigaz consolidated its market share by purchasing a majority stake in three natural gas distribution companies: Mol-Gàz (now Tigaz 2), Zsàmbèrkgàz and Turulgàz. In 2003, natural gas sales in Hungary amounted to 3.3 billion cubic meters. In 2003 customers supplied were approximately 1.1 million in 1,120 municipalities through an about 24,000-kilometer long network;
n |  | Argentina, through Distribuidora de Gas Cuyana SA (Eni’s interest 45.6%), which operates in the urban area of Mendoza, serving about 371,000 customers through a network of about 9,000 kilometers of pipelines. In 2003, it handled 1.8 billion cubic meters of natural gas; about 1 billion was sold to end users, while the rest was transported on behalf of third parties;
n |  | Slovenia, through Adriaplin Doo (Eni’s interest 51%), which distributes natural gas to about 8,000 customers in 17 urban centers through a network of about 363 kilometers of pipelines. In 2003, it sold 37 million cubic meters.

Supply

Eni’s natural gas requirements are met for about 82% with imports (mainly from Algeria, Russia, the Netherlands and Norway) under long-term contracts, and for the remaining part by purchases of gas produced in Italy by Eni’s Exploration & Production segment. Eni is a party in import contracts with an average residual duration of about 17 years which will provide a total of approximately 67.3 billion cubic meters of natural gas per year (28.5 from Russia, 21.5 from Algeria, 9.8 from the Netherlands, 6 from Norway and 1.5 from Nigeria) from 2008. Overall natural gas volumes under contract amount to approximately 1,088 billion cubic meters.

The so called territory destination clause for gas imported from Russia was cancelled: an agreement signed by Eni and Gazexport (Gazprom) allows Eni to sell the gas it purchases from Gazexport in countries other than Italy; Gazexport in turn can sell its gas to other Italian operators. This agreement was filed for approval to the European Commission, which concluded its exam of the contract, started when Eni and Gazexport agreed on the destination clause. The Commission requested Eni to assume additional obligations favoring competition, in particular: (i) Eni should make volumes of natural gas purchased from Gazexport available outside Italy; (ii) Eni shall promote the upgrading of the TAG gasline (from Austria into Italy) with deadlines consistent with the decision of third parties to build LNG terminals in Italy.

development projects

Eni is engaged in various development projects concerning the sale of natural gas in the rest of Europe in order to compensate the growth potential that cannot be developed in the domestic market, due to the limits set to operators. In Europe Eni can leverage on a positive competitive positioning as concerns gas availability, access to infrastructure, relations with producing countries and knowledge of markets. Based on the contracts and projects defined to date, Eni expects to sell 44 billion cubic meters of natural gas outside Italy by 2007.

GERMANY

Eni is present on the German natural gas market since late 2002 through GVS (Gasversorgung Süddeutschland GmbH) in which it acquired a 97.81% interest in joint venture with the German electricity operator EnBW. GVS is the fourth operator in the German gas market where it transports and markets about 7 billion cubic meters of gas per year to local distribution companies serving about 750 municipalities in the south-western areas of the country through an approximately 1,880-kilometer long gas pipeline network. Through GVS and the development of direct sales, Eni expects to sell about 4 billion cubic meters/year, of which 3.4 billion cubic meters of natural gas through GVS, corresponding to 4% of German consumption in 2007.

energy sector. Eni will concentrate in the natural gas sector through a 49% interest in Gas de Portugal (indirectly owned through Galp Energia) and will exit the segment of refining and marketing of refined products in Portugal where Eni operated through Galp Energia. Gas de Portugal will be managed jointly with Electricidade de Portugal, the other shareholder with a 51% interest; the natural gas transmission network owned by Gas de Portugal will be sold to a state-owned Portuguese company. This transaction entails cash proceeds of euro 667 million. The finalization of the agreement is subject to authorization from relevant antitrust authorities. In 2003 Galp sold about 3.8 billion cubic meters of natural gas to about 600,000 customers through a network of high, medium and low pressure pipelines about 9,000-kilometer long. Galp’s asset include interest two import infrastructures, the Transmaghreb pipeline and the Sines LNG terminal, that started operations in the fourth quarter of 2003, which provide Eni with a basis to access the Iberian market.

Spain

After obtaining the relevant authorizations from European antitrust authorities and the Spanish Government, in July 2003 Eni finalized the purchase of a 50% interest in Unió n Fenosa Gas (the remaining 50% being held by Unión Fenosa SA) with an outlay of euro 442 million. Unión Fenosa Gas is active in natural gas supply and sale to final users and to power generation companies. It holds a 25-year supply contract, with an option for a 25 year extension, involving 4 billion cubic meters per year with the Egyptian Natural Gas Holding Company (EGAS). It is active in LNG through a liquefaction plant with a capacity of over 7 billion cubic meters per year under construction near Damietta, on the Egyptian coast and through an 8% interest in a liquefaction plant under construction in Oman, which is expected to start operations in 2006. In addition, it holds a 19% and a 50% interest in the Reganosa and Sagunto regasification plants under construction, expected to start operations in 2005.

Through Unión Fenosa Gas, Gas de Portugal and the development of direct sales, Eni targets to sell about 6.7 billion cubic meters by 2007 in the Iberian Peninsula.

TURKEY - BLUE STREAM

Eni and Gazprom hold equal shares in Blue Stream Pipeline Company BV, which operates the Blue Stream transport system, that links the Russian (Beregovaya) to the Turkish (Samsun) coast of the Black Sea. The gasline transports natural gas produced in Russia which is sold jointly by Eni and Gazprom in Turkey to the Turkish company Botas under a long-term contract. Supplies to Botas started in February 2003, by year-end Botas had withdrawn approximately 1.3 billion cubic meters of natural gas (of which 633 million were Eni’s share). Volumes transported and marketed will increase progressively in future years and are targeted to about 16 billion cubic meters per year (8 billion net to Eni) in 2010.

GREECE

Eni holds a 49% interest in the natural gas secondary distribution companies EPA Thessalonica and EPA Thessaly. The two companies hold a 30-year licence for natural gas distribution to residential and commercial users as well as the right to use distribution networks. The two companies, whose operations are managed by Eni, are extending the distribution network in their areas covering about 2 million inhabitants. Natural gas sales of the two companies are targeted at 800 million cubic meters of natural gas per year.

LNG

Eni is a party in various initiatives in the area of LNG. In particular Eni holds a 10.4% interest in Nigeria LNG Co that manages the Bonny liquefaction plant. The plant, made up of three treatment trains with an overall capacity of 11.4 billion cubic meters/year of liquefied natural gas is undergoing an upgrade by means of the installation of two further trains which will increase its capacity to 21.8 billion cubic meters/year and are expected to be completed by the end of 2005.

power generation

Eni, through EniPower, is one of the major operators in electricity generation on the Italian market. Operating since 2000, EniPower owns power stations located at Eni’s sites in Brindisi, Ferrera Erbognone, Livorno, Mantova, Ravenna and Taranto with installed capacity in operation of approximately 1.9 gigawatts at December 31, 2003.

In 2003, Eni sold 8.7 terawatthour of electricity, of which about 5.6 produced by EniPower, corresponding to approximately 3% of the Italian market, and 9.3 million tonnes of steam. Eni intends to develop its electricity generation capacity and sales by exploiting the advantages provided by the integration of natural gas and electricity, targeting in 2006 an installed capacity of 5.3 gigawatts, corresponding about 11% of electricity generation planned in Italy at that date. Planned expenditure amounts to euro 2.3 billion, of this 1.2 already expensed. This objective will be pursued by building new capacity at Eni’s industrial sites. In particular work is underway at Ferrera Erbognone, Brindisi, Ravenna, and Mantova with total installed capacity of about 3.8 gigawatts (including the units started in 2003 at Ferrera Erbognone and Ravenna each with a capacity of 0.39 gigawatt) while authorizations are awaited for the new units (0.8 gigawatt) to be installed at Ferrara. High efficiency, low environmental impact, reduced expenditure and construction times are the main features of these plants, which show interesting profitability prospects due to the expected increase in demand for electricity and the ability to operate in co-generation (combined electricity and steam generation). The co-generation mode has been acknowledged by the Authority for Electricity and Gas as a production mode that entails priority on the national dispatching network and the exemption from the purchase of “green certificates”2. Eni estimates that EniPower power stations will allow to reduce total emissions of carbon dioxide by 8%, with negligible amounts of particulate and sulphur oxides as well as very low emissions of nitric oxides as compared to emissions caused by electricity generation in Italy in 2000. EniPower intends to become a cost leader in the Italian electricity industry thanks to the high technology content and optimal size the plants it is building. When fully operational, consumption of natural gas of Eni’s plants will reach about 6-7 billion cubic meters/year, supplied by Eni.

(2) |  | Article 11 of Legislative Decree No. 79/1999 concerning the opening up of the Italian electricity market obliges importers and producers of electricity from non renewable sources to input into the national electricity system a share of electricity produced from renewable sources set at 2% of electricity produced from non renewable sources exceeding 100 gigawatt. This obligation can be met also by purchasing volumes or rights from other producers employing renewable sources (the so called “green certificates”) to cover all or part of such 2% share. This obligation applies to import or production of electricity net of, among others, co-generation and volumes consumed in questions.

ROACE

Eni is engaged in the refining and sale of refined products mainly in Italy, the rest of Europe and Latin America. In distribution, with its Agip and IP brands, Eni is market leader in Italy. In 2003, Eni’s sales of refined products amounted to 49.9 million tonnes, of which 30.6 million tonnes in Italy. The processing capacity of Eni’s wholly-owned refineries was 25.2 million tonnes (equal to 504,000 barrels/day) at December 31, 2003.

In refining interventions are planned for rationalizing refining capacity by balancing production and demand and increasing refinery efficiency and flexibility. These actions will allow to increase conversion rates from the 60% average of the 2000-2003 period to 64% by 2007. Eni also intends to adjust the characteristics of its refined products to the evolution of fuel specifications in Europe focusing on fuels dedicated to specific market segments by leveraging on its integrated refining-logistics-distribution system.

In logistics Eni aims at increasing flexibility in order to allow the distribution of different high quality fuels and reducing costs by means of joint ventures with qualified partners. Eni intends to continue the process of requalification and strategic repositioning of the distribution network. In Italy by focusing on Agip branded service stations with high throughput and high non oil potential; in the rest of Europe by developing in selected areas. Eni’s objective in Italy is to reach European standards in terms of average throughput, services to customers and automation. In the rest of Europe Eni intends to strengthen its position in selected areas, in particular eastern Spain, southern France and Germany where it can obtain logistical and operating synergies and exploit the well-known Agip brand. Market shares will be increased by buying modern and well equipped services stations. Eni will intensify its efforts for efficiency improvements in all its business lines.

MAIN RESULTS

In 2003 Eni substantially completed the restructuring of its distribution network in Italy, aimed at reaching European standards in terms of average throughput and services to customers. The average throughput of Agip branded service stations in Italy increased by 26% (from 1.9 to 2.4 million liters)

The BluDiesel and High Fidelity initiatives confirmed their market success. BluDiesel, a low environmental impact gasoil, reached sales of 850 million liters, corresponding to 16% of all gasoil sales in Agip branded service stations. The High Fidelity campaign, which offers discounts to customers through personal cards, distributed 3.5 million cards, increasing by 30% over 2002; approximately 25% of Agip service stations’ throughput was sold via these cards

Sales of refined products on Eni’s network in the rest of Europe exceeded 3 million tonnes, with an 18% increase over 2002 as a consequence of a selective development strategy in markets with interesting growth prospects where Eni can leverage on the well known Agip brand and on logistic and operational synergies. In 2003 Eni purchased 410 services stations in Spain, Germany and France

Within the policy of specific focus on environmental protection and product quality, the construction of a tar gasification plant was started at the Sannazzaro refinery. This plant will produce synthesis gas from heavy fractions for the supply of the nearby EniPower electricity plant

Rationalizations and efficiency improvement actions generated cost savings by approximately euro 85 million

refining

Eni is engaged in refining activities in Italy and owns interests in refineries in Germany and the Czech Republic with a total refining capacity (balanced with conversion capacity) of 34 million tonnes (equal to 681,000 barrels/day), at December 31, 2003, with 29.2 million tonnes capacity in Italy.

Italy

Eni’s refining system in Italy is made up of five wholly owned refineries and a 50% and 28% interest in the Milazzo and Priolo refineries in Sicily, respectively. At December 31, 2003, Eni’s wholly owned refineries in Italy had a balanced capacity of 25.2 million tonnes (equal to 504,000 barrels/day), corresponding to over a fourth of Italian capacity and a conversion capacity of over 16.3 million tonnes, with a 58.8% conversion equivalent rate, one of the highest in Europe.

In 2003 total intake processing on own account amounted to 31.8 million tonnes (of these 8.4 million tonnes on refineries belonging to third parties, in particular Milazzo, Priolo and Saras). Total intake processing on wholly owned refineries amounted to 25.1 million tonnes with a nearly 100% utilization rate.

Eni confirms its strategy aimed at reducing Fob refining capacity in order to reach a total capacity of 30 million tonnes by 2007, increasing the share of Cif capacity from 65% of total capacity in 1999 to 83% in 2007. Eni also intends to improve refinery performance by means of: (i) creating more flexible operating structures, optimizing maintenance and reducing energy consumption; (ii) increasing the conversion index from 60% in the 2000-2003 period to about 64% by 2007, in order to improve its supply system and to adjust the characteristics of its refined products to the evolution of fuel specifications in Europe. Each of Eni’s Italian refineries is specialized based on its logistical configuration, geographic location and integration with other Eni business segments.

SANNAZZARO, with a balanced primary refining capacity of 160,000 barrels/day is one of the most efficient refineries in Europe. Located in the south-west of the Po Valley, at the confluence of the rivers Po and Ticino, it produces mainly gasolines, gasoil and other light products for the supply of markets in north-western Italy, Switzerland and Bavaria. Besides its primary distillation plants, this refinery contains two catalytic reforming plants used to increase the octane number of gasolines, an isomerization plant and three desulfurization plants, which allow a high degree of flexibility of production related to market and environmental conditions. The conversion plants are: a fluid catalytic cracker (FCC), an HDCK middle distillate conversion, and a Visbreaking thermal conversion. This refinery processes mainly oil from Russia, Africa and the North Sea incoming at the Genoa harbor and oil from Eni’s nearby Villafortuna field. From a logistical standpoint this refinery is located along the route of the Central Europe Pipeline, which links the Genoa terminal with French speaking Switzerland and Bavaria. In 2003 expenditure was dedicated to the upgrade of diesel fuel manufacture in line with new European regulations in force from 2005 and to the construction of a new tar (heavy residue from visbreaking) gasification plant that will produce syngas from fuel oil and will be used to fire the nearby EniPower power station.

GELA, with a balanced primary refining capacity of 100,000 barrels/day represents an upstream integrated pole with the production of heavy crudes obtained from nearby Eni fields offshore Sicily, while downstream it is integrated with Eni’s nearby petrochemical plants. Located on the southern coast of Sicily, it manufactures fuels for automotive use and residential heating purposes, as well as petrochemical feedstocks. Its high conversion level allows it to minimize the yield of fuel oil and semi-finished products. Besides its primary distillation plants, this refinery contains the following plants: an FCC reactor with advanced technology and two coking plants for the conversion of low grade feedstocks and vacuum conversion of heavy residues. All these plants are integrated in order to process heavy residues and manufacture valuable products and electricity. This refinery also contains modern residue and exhaust fume treatment plants which allow the complex to comply with the most exacting environmental standards. Oil and oil products are handled on land and by sea.

TARANTO, with a balanced primary refining capacity of 90,000 barrels/day, can process a wide range of crudes and semi-finished products with great operational flexibility. It mainly produces fuel for automotive use and residential heating purposes for the southeastern Italian markets. Besides its primary distillation plants, this refinery contains desulfurization plants and conversions plants such as: a two-stage thermal conversion plant (Visbreaking/thermal cracking) and an RHU conversion plant, one of the most advanced plants in the world with high yield of valuable products and low environmental impact. It processes most of the oil produced in Eni’s Val d’Agri fields carried to Taranto through the Monte Alpi pipeline; in 2003 a total of 2.1 million tonnes of this oil were processed. In 2003 the topping unit was upgraded in order to respond to the increasing availability of oil from the Val d’Agri fields.

LIVORNO, with a balanced primary refining capacity of 84,000 barrels/day, manufactures mainly gasolines, specialty products and lubricant bases. Besides its primary distillation plants, this refinery contains two gasoline treatment plants, an isomerization plant and an octanization plant for the manufacture of highly environmental friendly gasolines, as well an advanced solvex cycle for lubricant manufacture. Its pipeline links with the local harbor and with the Florence storage sites allow the Livorno facility to operate with great efficiency as concerns reception, handling and distribution of products. In 2003 plants were upgraded for the manufacture of higher viscosity lubricants (Group II bases) and the desulfurization of gasoil provided for by the new 2005 specifications.

PORTO MARGHERA, with a balanced primary refining capacity of 70,000 barrels/day, produces mainly gasolines and other light products for the supply of markets in north-eastern Italy, Austria, Slovenia and Croatia. Besides its primary distillation plants, this refinery contains a gasoline treatment plant, octanization plants and a two-stage thermal conversion plant (Visbreaking/thermal cracking) for increasing yields of valuable products. At year end the desulfurization plant was upgraded in order to comply with the new 2005 specifications.

Outside Italy

In Germany Eni holds an 8.3% interest in the SCHWEDT refinery and a 20% interest in BAYERNOIL, an integrated industrial pole including the Ingolstadt, Vohburg and Neustadt refineries. Eni’s refining capacity in Germany amounts to approximately 70,000 barrels/day. Eni’s share of the production of the three integrated refineries and of the Schwedt refinery is mainly used to supply Eni’s distribution network in Bavaria and Eastern Germany.

Eni holds a 16.33% interest in CESKA RAFINERSKA (CRC) which owns and manages two refineries, Kralupy and Litvinov, in the Czech Republic. In 2002 the CRC partners approved a plan under which the refinery provides a service of oil processing on account of its partners in proportion to their respective interests. This plan started up in the second half of 2003. Under this new arrangement Eni overall balanced conversion capacity increased by 27,000 barrels/day over 2002.

ITALY

At December 31, 2003, Eni’s retail distribution network consisted of 7,290 service stations (60% of which under the Agip brand), a 420 unit decrease over December 31, 2002, due to the sale of 281 service stations, the closure of 66 marginal stations and the negative balance of acquisitions and expirations of lease contracts (104 units), whose effects were offset in part by the purchase/construction of 31 new service stations.

Eni is implementing a process of requalification and strategic repositioning of its distribution network in Italy and in the rest of Europe. In Italy Eni continues the upgrading process of its retail network by developing its core network (stations with high throughput and high non oil retail potential), while the rationalization process is in its final phase. Eni’s objective is to reach European standards in terms of throughput, services provided to customers and automation. Eni targets an Agip branded network consisting of 4,180 service stations, a 30% market share and average throughput of about 2.8 million liters by 2007.

In this context the newly established IP company (operational since May 2002) consolidated its activity. The IP network consists of mainly leased service stations devoted to satisfying local markets, with an average throughput of 900,000 liters.
In 2003 markets confirmed the success of BluDiesel, a new diesel fuel with low environmental impact, sold in Agip branded service stations from the end of 2002. This environmentally advanced product was introduced into the market earlier than the regulation imposed by the European Union and was appreciated by motorists because it increases efficiency, reduces consumption and leaves the engine cleaner than traditional diesel fuel. This initiative gives value to the potential of the refining and marketing integrated system (refining-logistics-distribution) and launched a well identified product capable of meeting the requirements of more environmentally sensitive and technically exacting customers on a market that was considered undifferentiated.

In 2003 a total of 850 million liters of BluDiesel were sold, corresponding to 16% of total diesel fuel volumes sold on the Agip branded network on ordinary roads and highways and to 5.2% of all diesel fuel sales on the Italian market. At the end of 2003 about 3,700 Agip branded service stations were selling BluDiesel (about 1,500 at December 31, 2002).

In 2003 sales of refined products on retail markets amounted to 11 million tonnes, average throughput to 1,813,000 liters and market share was 36.6% (37.5% in 2002). In particular sales of Agip branded service stations amounted to 8.99 million tonnes with an average throughput of 2,418,000 liters. Market share of Agip branded service stations increased by 0.6 percentage points (from 29.4 in 2002 to 30% in 2003) also due to the success of BluDiesel. In view of improving fuel quality and services to customers, in 2003 on IP branded service stations sales of Plus 98 started. This new high quality gasoline with better performance in terms of efficiency and engine cleanliness was sold in about 800 service stations at December 31, 2003 (see “New technologies” below).

n Do it yourself campaign

Eni’s “Do-it-yourself” program allows motorists to obtain relevant savings by paying a price 0.021 and 0.026 euro per liter lower than the reference price, in about 3,000 Agip and IP branded service stations located on the ordinary network and highways respectively. In March 2002 Eni launched the “high fidelity” campaign in its self service stations, whereby customers provided with a special free card receive further discounts as a function of the total amount of purchased fuel with additional savings (1 cent/liter for the first 200 liters, 2 cents for the following 200 and 4 cents for volumes from 400 to 500 liters) which can be discounted at any time.

Within the process of upgrading its service station network by promoting customized services in 2003 Eni built: (i) three service stations dedicated to heavy transport, so called “Agip Truck Points”, strategically located on highways with the highest lorry traffic and provided with wide parking space, dedicated runways, personal services active 24 hours a day. In these service stations lorries can be washed and convenience stores are equipped with internet services; (ii) the first “Agip Multienergy” service station where all kinds of fuel are on sale (including also LPG and methane) which obtains part of the energy necessary for servicing from solar panels installed on its roof.

In 2003 Eni continued its “high fidelity” campaign which allows customers accessing self-service outlets provided with an electronic card to obtain price discounts as a function of the total amount of purchased fuel. The number of cards distributed exceeded 3.5 million (up 30% over 2002). The amount of fuel purchased with the card was about 25% of all fuel sold on Agip branded service stations.

The improvement in the quality of service to customers led to a further expansion of the automation process of the domestic network. At December 31, 2003 nearly all Agip branded service stations were provided with a corporate credit card system (94% in 2002). Eni continued the development of its non oil retail activities (retailing and catering) aimed at promoting the development of its network in line with European standards, such as the diffusion of self-service and innovative commercial outlets. To this end Eni owns master franchisor rights with exclusive rights for the oil sector for some international brands of the restaurant and catering sector.

In particular in 2003 the new Agip Caf# outlets were launched, and by year end 104 franchises were opened, while 8 new Pans & Co outlets were opened and convenience stores were reorganized under the new “SpazioAgip” brand name.

Eni intends to continue the development of its non oil activities and expects to provide 66% of its Agip branded network with these structures in the next four years.

In 2003 Eni continued the development of its Multicard paying card which covered 1.25 billion liters (up 7.2% over 2002), while the number of customers provided with this card increased from about 41,000 to 42,000. Multicard is used also by international fleets and is part of the international Routex consortium.

OFFSHORE CONSTRUCTION

Eni intends to consolidate its competitive positioning in the segment of large EPIC/EPC projects for the development of offshore and deep offshore hydrocarbon fields by integrating its technological and operational skills with engineering and project management capabilities acquired on the market (among which Bouygues Offshore, Moss Maritime, Petromarine, Idpe). The demand for these services is expected to increase, given the objective constraints to the expansion of hydrocarbon reserves in conventional environments. The development of deep offshore fields in the future will be performed more and more frequently by means of floating hydrocarbon production systems1, among which FPSOs are the most important due to their storage capacity which allows to develop fields remote from transmission infrastructure and to their versatility which allows to relocate vessels on nearby fields thus expanding their useful life. On the other hand the demand for fixed platforms for the development of offshore fields is slowly declining. Eni intends to increase its know-how in both floating oil production and storage systems and in LNG floating production systems that integrate production, storage, transport and regasification of natural gas.

Eni is recognized as one of the leading international companies for the design, procurement and installation of fixed platforms, in particular in the segment of ultra heavy lifting, thanks to the technical features of its vessels. It is a world leader in the laying of subsea pipelines and large diameter transmission infrastructure both in conventional

(1) Other floating production units are semisubmersible platforms, tension leg platforms and submersible pipe alignment rigs.

ONSHORE CONSTRUCTION

Eni operates in the construction of hydrocarbon treatment plants (separation, stabilization, collection of liquids and treatment of natural gas) and in the installation of large onshore transmission systems (pipelines, pumping and compression stations, terminals). Its main operation areas in the production/transmission area (upstream/midstream) are Central Asia, Africa and the Middle East. Eni intends to consolidate its competitive positioning in this segment by exploiting in particular the opportunities provided by frontier areas, characterized by the lack of infrastructure, where it can leverage on its distinctive ability to operate in difficult areas and to manage complex projects. Eni is also capable of providing onshore services complementary to offshore operations, which represents a competitive advantage for the development of projects in areas such as the Caspian Sea.

The downstream segment (refining, petrochemical, LPG plants and power stations), although providing less opportunities than the upstream segment, benefits from the expected expansion of the demand for services in the area of power generation.

ONSHORE DRILLING

Eni operates in this area as main contractor for the major international oil companies. Onshore drilling is conducted through 47 facilities located in Italy, Saudi Arabia, North Africa, Nigeria, Kazakhstan, Venezuela and Russia. Some of these facilities can drill to 10,000-meter depths in high pressure and high temperature environments. Eni intends to focus its activities in areas where it has been present for a long time and to search opportunities in areas with proved development prospects such as Central Asia, the Middle East and Russia.

In onshore drilling Eni developed extremely advanced technologies with a high degree of automation, which allow it to exploit the opportunities provided by the emergence of new logistically demanding remote areas lacking infrastructure that require the ability to operate in extreme environmental conditions.

LNG

Eni operates in the LNG market following its purchase of Bouygues Offshore which contributed its excellent competence in the area of liquefaction (in particular tanks) and regasification, complementary to the onshore and offshore transmission of natural gas. The markets offering the highest potential are the United States and Europe.

Energy and the Environment. Eni is active in the design and construction of combined cycle power stations. In 2003 combined cycle units were started-up for a total capacity of 1,200 megawatts at EniPower’s Ravenna and Ferrera Erbognone power stations. In the field of waste disposal Eni built 10 facilities for the incineration of industrial, noxious and solid urban waste. In particular, Eni holds a new proprietary technology for the total abatement of noxious elements present in fumes from combustion.

FIELD UPSTREAM FACILITIES AND PIPELINES

Eni holds relevant competitive positions in the area of design and construction of pipelines for the transmission of hydrocarbons, for collection networks and upstream plants (construction of primary separation plants, gas and water injection systems, compression and pumping stations), the demand for which is expected to grow. Eni has new advanced technologies for the construction of high pressure pipelines in deep waters for long distance transmission of large volumes of natural gas and intends to strengthen its competitive positioning in this area by leveraging its know-how and expertise.

INFRASTRUCTURE

Eni is active in the field of design and construction of great infrastructure in Italy. The Italian market for great infrastructure shows interesting prospects after the approval of a 10-year plan for the construction of large infrastructure by the Italian Government. The types of works, their size, the introduction of simpler and faster authorization procedures, the modes of implementation of projects based on their critical variables (time, cost, quality) and the acknowledgement of the role of General Contractors are the elements on which Eni bases its efforts to win orders in this area.

n Project high speed/high capacity train tracks from Milan to Bologna and from Milan to Verona

In 1991, Snamprogetti, through its interest in Cepav Uno and Cepav Due consortia, signed two conventions with TAV SpA to participate in the construction of the tracks for high speed trains from Milan to Bologna and from Milan to Verona. Eni holds a majority stake in both Cepav Uno (50.36%) building the track from Milan to Bologna (under construction) and Cepav Due (52%), building the track from Milan to Verona (still in the design phase).

Within the project for the construction of the tracks for high speed/high capacity trains from Milan to Bologna, an addendum to the contract between Cepav Uno and TAV SpA was signed in June. Major changes concern the continuation of works, the division of works into five functional stages that are expected to be completed between the spring of 2006 and late 2008, a lump sum payment related to the new 30 changes.

Works completed at the end of 2003 correspond to 40% of the total.

As concerns the Milan to Verona section, on December 5, 2003 the Government approved the preliminary project; the further step is the signing of an integration deed.

new technologies

Eni is aware of the key role innovative technologies play in the future development of the hydrocarbon industry, it therefore intends to integrate R&D expertise and its industrial application, focusing on innovative strategic projects capable of creating competitive advantages. Research projects are going to be selected according to a strict evaluation of their return; ongoing projects are going to be monitored in light of the maximization of the value of Eni’s project portfolio. In the next four years Eni intends to significantly increase the resources it deploys in R&D and will focus on lines that can respond to expected market trends in the long- to medium-term; in particular: (i) reduction of mineral risk; (ii) enhanced recovery of hydrocarbons; (iii) optimal management of reserves with high acid gas content (e.g. sulphur); (iv) upgrading of heavy and ultra heavy crudes; (v) high pressure transmission of natural gas; (vi) conversion of natural gas to liquids in order to give value to associated gas or natural gas produced in remote locations; (vii) manufacture of high quality fuels and alternative fuels with better engine and environmental performance; (viii) hydrogen as energy vector.

Eni intends to search global alliances in order to participate in research projects that have a longer horizon than the four-year plan. Follows a brief description of the main techniques applied or under development.

Hydrocarbon exploration and production

INNOVATIVE TECHNOLOGIES FOR SUBSOIL SURVEY

In order to prepare a geological model of fields as near as possible to reality and therefore to reduce exploration risks and uncertainties related to fields, Eni developed significant industrial applications of highly innovative technologies. In particular, the so called CRS Stack (Common Reflection Surface Stack) is able to process seismic imaging and to obtain information on the Òvelocity modelÓ with significantly higher results than conventional technologies. This allowed to improve the final seismic image of the Elephant field in Libya. Significant developments derived also from the development and/or application of advanced technologies for modelling and monitoring fields: innovative technologies for studying fractured fields, cross-well seismics, 4D time lapse seismics to monitor the behaviour of producing fields over time.

DRILLING OF “ADVANCED WELLS”

Eni developed and applied at industrial level a series of technologies that allow to drill highly complex wells with greater operating efficiency. “Lean profile” drilling, developed and patented by Eni, is applied in deep vertical and deviated wells especially in high pressure and high temperature environments allowing a reduction in time and costs as wells as the final environmental impact as it reduces the volume of rock handled. Wells obtained with this technique are high quality and low risk. It basically consists in reducing to a minimum the tolerance between the diameter of wells and their lining columns while keeping the production casing unchanged. The verticality and direction of the hole are guaranteed by innovative tools such as “Vertitrack” (former SDD, straight-hole drilling device) and “Autotrack” developed and applied by Eni in cooperation with Baker-Hughes. Lean drilling was successfully applied both in Italy (Val d’Agri, Trecate) and outside Italy (Tunisia, Algeria, Egypt and Russia) and entailed significant benefits such as higher safety and higher savings of costs and time. The ultra deep HP/HT well recently drilled in Russia represents a world record for this technology with its 6,826 meters of total depth and the use of a 13”3/8 casing at 4,016 meters lowered in a 14”3/4 hole. The application

##### Table of Contents

in Val d’Agri is a record lean drilling in highly deviated wells (a 13”3/8 casing in a 14”3/4 hole with inclination up to 60º).

In deep water drilling Eni’s innovative proprietary technology is the dual casing running which allows for simultaneous drilling of the first two superficial holes of a deep water well, the simultaneous lowering of the superficial casings and the cementing. The application of this technology allows for a significant reduction in time and costs and a perfect verticality of the two casings and the well head.

INNOVATIVE TECHNOLOGIES FOR THE TREATMENT OF LIQUIDS

In the field of transmission and treatment of hydrocarbons Eni developed and applied innovative technologies with particular attention to multi-phase fluids (water, oil and/or gas) in order to optimize production and reduce its environmental impact.

In particular, Eni successfully tested at its Cavone oil center a pilot plant for the removal of oils from layer waters which allows to reduce the residual concentration of hydrocarbons in water to less than 10 ppm, starting from an initial content of 1,000 ppm. The system is based on the use of adsorbing polymers capable first to capture oil particles and then to release them favoring their coalescence and making them easier to separate. The system is currently being engineered in order to make it useable on platforms. Another ongoing project aims at optimizing new design centrifugal systems for the separation of water from oil and for the confirmation of innovative technologies for removing soluble organic compounds.

Also in the field of multiphase pumping Eni is applying innovative technologies as an alternative to traditional production systems in marginal fields, fields located in frontier areas or difficult areas such as deep waters. The multiphase technology becomes extremely useful, in terms of economic benefits, in offshore applications where the possibility to transport production from the wells over long distances allows to transfer processing activities on existing facilities and infrastructure, thus significantly reducing technical costs for the development of fields. Infield applications of multiphase pumping have been recently installed offshore and onshore in the United Kingdom and Tunisia with other partners in order to obtain a higher recovery of hydrocarbons.

MANAGEMENT OF HYDROGEN SULPHIDE AND SULPHUR

In 2003 Eni started an important R&D project for the optimal management of reserves with high content of hydrogen sulphide and sulphur. The project aimed at developing innovative technologies and/or advanced processes able to manage the disposal and possible exploitation of high amounts of acid gas and sulphur that are produced with hydrocarbons, while respecting safety and the environment. In particular the study concerns innovative processes for the separation of hydrogen sulphide and its conversion into plain sulphur and the storage and/or use of this sulphur. In parallel innovative processes are being studied for the reinjection of hydrogen sulphide into the field and its monitoring.

Eni Slurry Technology

Eni Slurry Technology (EST) is a strategically relevant technique that is being developed for meeting the growing need for the upgrading of heavy crudes and non conventional crudes (asphalt sands) and for the transformation and enhancement of refining residues. EST is a hydrogenating treatment technique which acts on heavy residues from extra-heavy crudes with high content of polluting substances (sulphur, metals, nitrogen compounds and with high Conradson Carbon Residue - CCR). The strategic interest of upgrading heavy crudes derives from the need felt by the oil industry: (i) to enhance relevant reserves of heavy crudes thus increasing proved reserves without recourse to new exploration expenditure; (ii) to requalify the productive structure of most refineries by turning refining residues into valuable products without building additional capacity; (iii) to reduce the environmental impact of refining by eliminating fuel oil which is turned into valuable products and indirectly contributing to the increase in natural gas demand and

to the reduction of carbon dioxide emissions. At present this technology is characterized by: (i) feedstock flexibility; (ii) high quality of finished products; (iii) total conversion of processing residues; (iv) no production of fuel oil and coke. Within the development and the pre-marketing phases, a Commercial Demonstration Plant (CDP) is nearing completion at Eni’s Taranto refinery with a 1,200 barrels/day capacity and is expected to start operations at the end of 2004.

Transmission: TAP Project

The TAP Project (High Pressure Transmission) aims at developing reliable technologies for making the transmission via pipeline of relevant amounts of natural gas from production areas to the most promising markets economically viable (gas-to-market). This project was started in May 2003 and is expected to last for three years. Activity is aimed at developing the most advanced long distance, high capacity, high pressure and high grade solutions with relevant targets related to: (i) distances over 3,000 kilometers; (ii) natural gas volumes to be transported of about 20-30 billion cubic meters/year; (iii) pressure equal to or higher than 15 Mpa and (iv) use of high and very high grade steel (e.g. X100). The project phases are: (i) evaluation of the viability of alternative solutions in frontier initiatives; (ii) technological upgrading within the Eni Group and by participating in international R&D projects; (iii) technical-economic evaluation of transport along strategic routes and comparison with LNG solutions; (iv) construction of a portion of pipeline type DN 1200 10-kilometer long in X80 steel along an Italian transport route; (v) construction of a portion of pipe DN 1200 in X100 steel operated under high pressure in a testing area in order to evaluate the various design, construction and operation options over time.

Conversion of natural gas into liquids

At Eni’s Sannazzaro refinery a pilot plant for the conversion of syngas to a mixture of paraffin hydrocarbons (wax) is operating. Aim of the project is to exploit the enormous volumes of natural gas that are not extracted because too far from end markets and of volumes of natural gas associated to oil for which the only option is reinjection into wells and that could negatively affect liquid production. The conversion of gas allows to manufacture of high quality refined products such as naphtha, kerosene and diesel fuel, totally sulphur and aromatic free. This plant produces 20 barrels/day of wax by means of an advanced technology (Fischer-Tropsch) studied in cooperation with the Institut Francais du Pétrole (IFP) and EniTecnologie (100% Eni). The project was started in 1996 and allowed for the filing of 44 patents. Along with the completion of the second test phase in the pilot plant (to be completed by the autumn of 2004), which will consolidate the process book of the hydrocarbon synthesis section, the feasibility study for the commercial developments of the project is underway.

Eni and IFP are also cooperating to the development of a specific hydrocracking process for the conversion of wax into liquid hydrocarbons with maximization of yields of middle distillates (diesel fuel and kerosene).

Innovative fuels: Plus 98

In July 2003 on IP branded service stations sales of Plus 98 started. This new high quality gasoline with better performance in terms of efficiency than conventional gasoline has its major advantages in: (i) an octane number (over 98) three points higher than conventional gasoline which allows a more regular burning, optimizing the process of transformation of available energy into mechanical energy; (ii) easier vaporization, i.e the fuel’s ability to turn from liquid into vapour, which allows Plus 98 to mix faster with air and produce faster combustion, thus increasing the engine’s response; (iii) detergent power: Plus 98 contains a special additive that prevents the formation of deposits in the engine

feeding system, in particular in valves, allowing the engine to maintain its performance over time.

With Plus 98 Eni confirms its constant attention for the quality of its fuels and the optimization of engine performance and its protection.

Hydrogen and Syngas System

The first phase of the Hydrogen and Syngas System research program was completed. The project aimed at increasing the utilization rate and the environmental sustainability of fossil energy sources and, based on the indications emerged, a new project was started for the industrial development of a new kind of multi-fuel reforming based on catalytic oxidation with low contact time (SCT-CPO) of various kinds of hydrocarbon feedstocks, in particular low value and marginal feedstocks produced in the refinery with high content of polyaromatic and sulphur compounds. If this project is successful it will be possible to meet the demand for hydrogen required for the hydrotreatment units manufacturing clean fuels at a reasonable cost. This technology will be tested in a pilot plant that will be built at the Centro Ricerche Sud in Milazzo in the spring of 2005.

Technologies for the development of hydrogen as energy vector

Oil and natural gas reserves

Proved oil and gas reserves are the estimated quantities of crude oil, natural gas and natural gas liquids which geological and engineering data demonstrate with reasonable certainty to be recoverable in future years from known reservoirs under technical, contractual, economic and operating conditions existing at the time. Prices include consideration of changes in existing prices provided only by contractual arrangements, but not on escalations based upon future conditions. Proved reserves exclude royalties and interests owned by others.

Proved developed reserves are proved reserves that can be estimated to be recovered through existing wells with existing equipment and operating methods.

Proved undeveloped oil and gas reserves are reserves that are expected to be recovered from new wells on undrilled acreage, or from existing wells where a relatively major expenditure is required for completion.

Additional oil and gas reserves expected to be obtained through the application of fluid injection or other improved recovery techniques for supplementing natural forces and mechanisms of primary recovery are included as proved developed reserves only after testing by a pilot project or after the operation of an installed program has confirmed through production response that increased recovery will be achieved.

The estimates of Eni’s reserve quantities have been prepared in accordance with applicable U.S. Securities and Exchange Commission regulation. The estimates of proved reserves, developed and undeveloped are based on data prepared by Eni.

Eni operates under PSAs in several of the foreign jurisdictions where it has oil and gas exploration and production activities. In countries where Eni operates under PSAs, proved reserves are shown in accordance with Eni’s economic interest (pursuant to PSA contract terms) in the oil and gas reserve quantities estimated to be recoverable in future years. Such reserves include estimated quantities allocated to Eni for recovery of costs, income taxes owed by Eni but settled by its joint venture partners (which are state-owned entities) out of Eni’s share of production, and Eni’s net equity share after cost recovery.

Proved reserves include the volume of natural gas used for own consumption and volumes of natural gas held in certain Eni storage fields in Italy. Proved reserves attributable to these fields include: (i) the residual natural gas volumes of the reservoirs; (ii) natural gas volumes from other Eni fields input into these reservoirs in subsequent periods. Proved reserves do not include volumes owned by or acquired from third parties. Gas withdrawn from storage is produced and thereby detracted from proved reserves when it is sold to third parties.

Numerous uncertainties are inherent in estimating quantities of proved reserves and in projecting future rates of production and timing of development expenditures. The accuracy of any reserve estimate is a function of the quality of available data and engineering and geological interpretation and judgement. Results of drilling, testing and production after the date of the estimate may require substantial upward and downward revision. In addition, changes in oil and natural gas prices could have an effect on the quantities of Eni’s proved reserves because the estimates of reserves are based on prices and costs at the date when such estimates are made. Reserves estimates are also subject to revision as prices fluctuate due to the cost recovery feature under certain PSAs.

The following table presents yearly changes in estimated proved reserves, developed and undeveloped, of crude oil (including condensate and natural gas liquids) and natural gas.

(1) |  | Results of operations from oil and gas producing activities including services for the modulation of gas supply due to seasonal swings in demand, represent only those revenues and expenses directly associated with Eni’s oil and gas production. These amounts do not include any allocation of interest expense or corporate overhead and, therefore, are not necessarily indicative of the contributions to consolidated net earnings of Eni. Revenues and income taxes include taxes due in PSA’s where Eni’s tax liability is paid by the State Company on behalf of Eni. Such income taxes have been calculated by applying the tax rate of the country where Eni operates to the pretax income from exploration and production activities.

SUPPLEMENTAL OIL AND GAS INFORMATION

##### Table of Contents

Standardized measure of discounted future net cash flows

Estimated future cash inflows represent the revenues that would be received from production and are determined by applying year-end prices of oil and gas to the estimated future production of proved reserves. Future price changes are considered only to extent provided by contractual arrangements. Estimated future development and production costs are determined by estimating the expenditures to be incurred in developing and producing the proved reserves at the end of the year. Neither the effects of price and cost escalations nor expected future changes in technology and operating practices have been considered.

The standardized measure is calculated as the excess of future cash inflows from proved reserves less future costs of producing and developing the reserves, future income taxes and a yearly 10% discount factor.

Future cash flows as of December 31, 2001, 2002 and 2003 include annual revenue payments from Eni’s Gas & Power segment and other transport and distribution gas companies which represent payments for modulation services to support demand delivery capability. Such capability is provided through utilization of gas withdrawn from producing fields and injected into depleted gas fields as storage.

Future production costs include the estimated expenditures related to the production of proved reserves plus any production taxes without consideration of future inflation. Future development costs include the estimated costs of drilling development wells and installation of production facilities, plus the net costs associated with dismantlement and abandonment of wells and facilities, under the assumption that year-end costs continue without considering future inflation. Future income taxes were calculated in accordance with the tax laws of the countries in which Eni operates. The standardized measure of discounted future net cash flows, related to the preceding proved oil and gas reserves, is calculated in accordance with the requirements of Statement of Financial Accounting Standard No. 69. The standardized measure does not purport to reflect realizable values or fair market value of Eni’s proved reserves. An estimate of fair value would also take into account, among other things, the expected recovery of reserves in excess of proved reserves, anticipated changes in future prices and costs and a discount factor representative of the risks inherent in producing oil and gas.
