NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)
1. Summary of Significant Accounting Policies
General. The condensed consolidated financial statements of EOG Resources, Inc., together with its subsidiaries (collectively, EOG), included herein have been prepared by management without audit pursuant to the rules and regulations of the United States Securities and Exchange Commission (SEC). Accordingly, they reflect all normal recurring adjustments which are, in the opinion of management, necessary for a fair presentation of the financial results for the interim periods presented. Certain information and notes normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP) have been condensed or omitted pursuant to such rules and regulations. However, management believes that the disclosures included either on the face of the financial statements or in these notes are sufficient to make the interim information presented not misleading. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto included in EOG's Annual Report on Form 10-K for the year ended December 31, 2018, filed on February 26, 2019 (EOG's 2018 Annual Report).
The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The operating results for the three and six months ended June 30, 2019, are not necessarily indicative of the results to be expected for the full year.
Effective January 1, 2019, EOG adopted the provisions of Accounting Standards Update (ASU) 2016-02, "Leases (Topic 842)" (ASU 2016-02). ASU 2016-02 and other related ASUs require that lessees recognize a right-of-use (ROU) asset and related lease liability, representing the obligation to make lease payments for certain lease transactions, on the Condensed Consolidated Balance Sheets and disclose additional leasing information.
EOG elected to adopt ASU 2016-02 and other related ASUs using the modified retrospective approach with a cumulative-effect adjustment to the opening balance of retained earnings as of the effective date. Financial results reported in periods prior to January 1, 2019, are unchanged. Additionally, EOG elected the package of practical expedients within ASU 2016-02 that allows an entity to not reassess prior to the effective date (i) whether any expired or existing contracts are or contain leases, (ii) the lease classification for any expired or existing leases, or (iii) initial direct costs for any existing leases, but did not elect the practical expedient of hindsight when determining the lease term of existing contracts at the effective date. EOG also elected the practical expedient under ASU 2018-01, "Leases (Topic 842) - Land Easement Practical Expedient for Transition to Topic 842," and did not evaluate existing or expired land easements not previously accounted for as leases prior to the January 1, 2019 effective date. There was no impact to retained earnings upon adoption of ASU 2016-02 and other related ASUs. See Note 14.
2. Stock-Based Compensation
As more fully discussed in Note 7 to the Consolidated Financial Statements included in EOG's 2018 Annual Report, EOG maintains various stock-based compensation plans. Stock-based compensation expense is included on the Condensed Consolidated Statements of Income and Comprehensive Income based upon the job function of the employees receiving the grants as follows (in millions):

| Three Months Ended June 30, |  | Six Months Ended June 30,
| 2019 |  | 2018 |  | 2019 |  | 2018
Lease and Well | $ | 13.6 |  |  | $ | 11.4 |  |  | $ | 27.3 |  |  | $ | 24.2 |
Gathering and Processing Costs | 0.3 |  |  | 0.1 |  |  | 0.5 |  |  | 0.2 |
Exploration Costs | 6.5 |  |  | 5.7 |  |  | 13.0 |  |  | 12.6 |
General and Administrative | 18.2 |  |  | 14.6 |  |  | 36.9 |  |  | 30.3 |
Total | $ | 38.6 |  |  | $ | 31.8 |  |  | $ | 77.7 |  |  | $ | 67.3 |

The Amended and Restated EOG Resources, Inc. 2008 Omnibus Equity Compensation Plan (2008 Plan) provides for grants of stock options, stock-settled stock appreciation rights (SARs), restricted stock and restricted stock units, performance units and other stock-based awards.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS – (Continued)
(Unaudited)
At June 30, 2019, approximately 13.0 million common shares remained available for grant under the 2008 Plan. EOG's policy is to issue shares related to 2008 Plan grants from previously authorized unissued shares or treasury shares to the extent treasury shares are available.
Stock Options and Stock-Settled Stock Appreciation Rights and Employee Stock Purchase Plan. The fair value of stock option grants and SAR grants is estimated using the Hull-White II binomial option pricing model. The fair value of Employee Stock Purchase Plan (ESPP) grants is estimated using the Black-Scholes-Merton model. Stock-based compensation expense related to stock option, SAR and ESPP grants totaled $13.6 million and $11.7 million during the three months ended June 30, 2019 and 2018, respectively, and $27.5 million and $23.7 million during the six months ended June 30, 2019 and 2018, respectively.
Weighted average fair values and valuation assumptions used to value stock option, SAR and ESPP grants during the six-month periods ended June 30, 2019 and 2018 are as follows:

| Stock Options/SARs |  | ESPP
| Six Months Ended June 30, |  | Six Months Ended June 30,
| 2019 |  | 2018 |  | 2019 |  | 2018
Weighted Average Fair Value of Grants | $ | 25.68 |  |  | $ | 29.18 |  |  | $ | 22.98 |  |  | $ | 23.27 |
Expected Volatility | 31.50 | % |  | 28.88 | % |  | 36.31 | % |  | 22.04 | %
Risk-Free Interest Rate | 2.38 | % |  | 2.23 | % |  | 2.48 | % |  | 1.60 | %
Dividend Yield | 0.96 | % |  | 0.67 | % |  | 0.83 | % |  | 0.66 | %
Expected Life | 5.1 years |  | 5.0 years |  |  | 0.5 years |  |  | 0.5 years |

Expected volatility is based on an equal weighting of historical volatility and implied volatility from traded options in EOG's common stock. The risk-free interest rate is based upon United States Treasury yields in effect at the time of grant. The expected life is based upon historical experience and contractual terms of stock option, SAR and ESPP grants.
The following table sets forth stock option and SAR transactions for the six-month periods ended June 30, 2019 and 2018 (stock options and SARs in thousands):

| Six Months Ended June 30, 2019 |  | Six Months Ended June 30, 2018

Exercisable at June 30 (4) | 3,905 |  |  | $ | 86.71 |  |  | 2,938 |  |  | $ | 78.74 |

(1) | The total intrinsic value of stock options/SARs exercised during the six months ended June 30, 2019 and 2018 was $3.9 million and $74.5 million, respectively. The intrinsic value is based upon the difference between the market price of EOG's common stock on the date of exercise and the grant price of the stock options/SARs.

(2) | The total intrinsic value of stock options/SARs outstanding at June 30, 2019 and 2018 was $45.0 million and $277.2 million, respectively. At June 30, 2019 and 2018, the weighted average remaining contractual life was 4.0 years and 4.3 years, respectively.

(1) | The total intrinsic value of restricted stock and restricted stock units released during the six months ended June 30, 2019 and 2018 was $35.7 million and $34.9 million, respectively. The intrinsic value is based upon the closing price of EOG's common stock on the date the restricted stock and restricted stock units are released.

(2) | The total intrinsic value of restricted stock and restricted stock units outstanding at June 30, 2019 and 2018 was $347.5 million and $468.2 million, respectively.

At June 30, 2019, unrecognized compensation expense related to restricted stock and restricted stock units totaled $158.2 million. Such unrecognized expense will be amortized on a straight-line basis over a weighted average period of 1.7 years.
Performance Units. EOG grants performance units annually to its executive officers without cost to them. As more fully discussed in the grant agreements, the performance metric applicable to the performance units is EOG's total shareholder return over a three-year performance period relative to the total shareholder return of a designated group of peer companies (Performance Period). Upon the application of the performance multiple at the completion of the Performance Period, a minimum of 0% and a maximum of 200% of the performance units granted could be outstanding. The fair value of the performance units is estimated using a Monte Carlo simulation. Stock-based compensation expense related to the performance unit grants totaled $1.9 million and $1.1 million for the three months ended June 30, 2019 and 2018, respectively, and $3.8 million and $2.3 million for the six months ended June 30, 2019 and 2018, respectively.

8. Commitments and Contingencies
There are currently various suits and claims pending against EOG that have arisen in the ordinary course of EOG's business, including contract disputes, personal injury and property damage claims and title disputes. While the ultimate outcome and impact on EOG cannot be predicted, management believes that the resolution of these suits and claims will not, individually or in the aggregate, have a material adverse effect on EOG's consolidated financial position, results of operations or cash flow. EOG records reserves for contingencies when information available indicates that a loss is probable and the amount of the loss can be reasonably estimated.
9. Pension and Postretirement Benefits
EOG has defined contribution pension plans in place for most of its employees in the United States, and a defined benefit pension plan covering certain of its employees in Trinidad. For the six months ended June 30, 2019 and 2018, EOG's total costs recognized for these pension plans were $23.0 million and $20.2 million, respectively. EOG also has postretirement medical and dental plans in place for eligible employees and their dependents in the United States and Trinidad, the costs of which are not material.
10. Long-Term Debt and Common Stock
Long-Term Debt. EOG had no outstanding commercial paper borrowings or uncommitted credit facility borrowings at June 30, 2019 and December 31, 2018, and did not utilize any such borrowings during the six months ended June 30, 2019. During the six months ended June 30, 2018, EOG utilized commercial paper borrowings, bearing market interest rates, for various corporate financing purposes. The average borrowings outstanding under the commercial paper program was $17 million during the six months ended June 30, 2018. The weighted average interest rate for commercial paper borrowings during the six months ended June 30, 2018, was 1.97%.
On June 3, 2019, EOG repaid upon maturity the $900 million aggregate principal amount of its 5.625% Senior Notes due 2019.
On June 27, 2019, EOG entered into a new $2.0 billion senior unsecured Revolving Credit Agreement (New Facility) with domestic and foreign lenders (Banks). The New Facility replaces EOG’s $2.0 billion senior unsecured Revolving Credit Agreement, dated as of July 21, 2015, with domestic and foreign lenders (2015 Facility), which had a scheduled maturity date of July 21, 2020 and which was terminated by EOG (without penalty), effective as of June 27, 2019, in connection with the completion of the New Facility.
The New Facility has a scheduled maturity date of June 27, 2024, and includes an option for EOG to extend, on up to two occasions, the term for successive one-year periods subject to certain terms and conditions. The New Facility (i) commits the Banks to provide advances up to an aggregate principal amount of $2.0 billion at any one time outstanding, with an option for EOG to request increases in the aggregate commitments to an amount not to exceed $3.0 billion, subject to certain terms and conditions, and (ii) includes a swingline subfacility and a letter of credit subfacility. Advances under the New Facility will accrue interest based, at EOG’s option, on either the London InterBank Offered Rate plus an applicable margin (Eurodollar Rate) or the Base Rate (as defined in the New Facility) plus an applicable margin. The applicable margin used in connection with interest rates and fees will be based on EOG’s credit rating for its senior unsecured long-term debt at the applicable time.
Consistent with the terms of the 2015 Facility, the New Facility contains representations, warranties, covenants and events of default that we believe are customary for investment grade, senior unsecured commercial bank credit agreements, including a financial covenant for the maintenance of a ratio of total debt-to-total capitalization (as such terms are defined in the New Facility) of no greater than 65%. At June 30, 2019, EOG was in compliance with this financial covenant.
There were no borrowings or letters of credit outstanding under the 2015 Facility as of (i) December 31, 2018 or (ii) the June 27, 2019 effective date of the closing of the New Facility and termination of the 2015 Facility. Further, at June 30, 2019, there were no borrowings or letters of credit outstanding under the New Facility. The Eurodollar Rate and Base Rate (inclusive of the applicable margin), had there been any amounts borrowed under the New Facility at June 30, 2019, would have been 3.30% and 5.50%, respectively.

11. Fair Value Measurements
As more fully discussed in Note 13 to the Consolidated Financial Statements included in EOG's 2018 Annual Report, certain of EOG's financial and nonfinancial assets and liabilities are reported at fair value on the Condensed Consolidated Balance Sheets. The following table provides fair value measurement information within the fair value hierarchy for certain of EOG's financial assets and liabilities carried at fair value on a recurring basis at June 30, 2019 and December 31, 2018 (in thousands):

| Fair Value Measurements Using:

The estimated fair value of commodity derivative contracts was based upon forward commodity price curves based on quoted market prices. Commodity derivative contracts were valued by utilizing an independent third-party derivative valuation provider who uses various types of valuation models, as applicable.
The initial measurement of asset retirement obligations at fair value is calculated using discounted cash flow techniques and based on internal estimates of future retirement costs associated with property, plant and equipment. Significant Level 3 inputs used in the calculation of asset retirement obligations include plugging costs and reserve lives. A reconciliation of EOG's asset retirement obligations is presented in Note 6.
Proved oil and gas properties and other assets with a carrying amount of $413 million were written down to their fair value of $322 million, resulting in pretax impairment charges of $91 million for the six months ended June 30, 2019. Included in the $91 million pretax impairment charges are $89 million for a commodity price-related write-down of other assets.
EOG utilized average prices per acre from comparable market transactions and estimated discounted cash flows as the basis for determining the fair value of unproved and proved properties, respectively, received in non-cash property exchanges. See Note 4.
Fair Value of Debt. At June 30, 2019 and December 31, 2018, respectively, EOG had outstanding $5,140 million and $6,040 million aggregate principal amount of senior notes, which had estimated fair values at such dates of approximately $5,387 million and $6,027 million, respectively. The estimated fair value of debt was based upon quoted market prices and, where such prices were not available, other observable (Level 2) inputs regarding interest rates available to EOG at the end of each respective period.

12. Risk Management Activities
Commodity Price Risk. As more fully discussed in Note 12 to the Consolidated Financial Statements included in EOG's 2018 Annual Report, EOG engages in price risk management activities from time to time. These activities are intended to manage EOG's exposure to fluctuations in commodity prices for crude oil and natural gas. EOG utilizes financial commodity derivative instruments, primarily price swap, option, swaption, collar and basis swap contracts, as a means to manage this price risk. EOG has not designated any of its financial commodity derivative contracts as accounting hedges and, accordingly, accounts for financial commodity derivative contracts using the mark-to-market accounting method.
Commodity Derivative Contracts. Prices received by EOG for its crude oil production generally vary from U.S. New York Mercantile Exchange (NYMEX) West Texas Intermediate prices due to adjustments for delivery location (basis) and other factors. EOG has entered into crude oil basis swap contracts in order to fix the differential between pricing in Midland, Texas, and Cushing, Oklahoma (Midland Differential). Presented below is a comprehensive summary of EOG's Midland Differential basis swap contracts for the six months ended June 30, 2019. The weighted average price differential expressed in dollars per barrel ($/Bbl) represents the amount of reduction to Cushing, Oklahoma, prices for the notional volumes expressed in barrels per day (Bbld) covered by the basis swap contracts.

EOG has also entered into crude oil basis swap contracts in order to fix the differential between pricing in the U.S. Gulf Coast and Cushing, Oklahoma (Gulf Coast Differential). Presented below is a comprehensive summary of EOG's Gulf Coast Differential basis swap contracts for the six months ended June 30, 2019. The weighted average price differential expressed in $/Bbl represents the amount of addition to Cushing, Oklahoma, prices for the notional volumes expressed in Bbld covered by the basis swap contracts.

(1) | The current portion of Assets from Price Risk Management Activities consists of gross assets of $138 million, partially offset by gross liabilities of $3 million at June 30, 2019.

Credit Risk. Notional contract amounts are used to express the magnitude of a financial derivative. The amounts potentially subject to credit risk, in the event of nonperformance by the counterparties, are equal to the fair value of such contracts (see Note 11). EOG evaluates its exposure to significant counterparties on an ongoing basis, including those arising from physical and financial transactions. In some instances, EOG renegotiates payment terms and/or requires collateral, parent guarantees or letters of credit to minimize credit risk.
All of EOG's derivative instruments are covered by International Swap Dealers Association Master Agreements (ISDAs) with counterparties. The ISDAs may contain provisions that require EOG, if it is the party in a net liability position, to post collateral when the amount of the net liability exceeds the threshold level specified for EOG's then-current credit ratings. In addition, the ISDAs may also provide that as a result of certain circumstances, including certain events that cause EOG's credit ratings to become materially weaker than its then-current ratings, the counterparty may require all outstanding derivatives under the ISDAs to be settled immediately. See Note 11 for the aggregate fair value of all derivative instruments that were in a net asset position at June 30, 2019 and December 31, 2018. EOG had no collateral posted and held collateral of $4 million at June 30, 2019. EOG had no collateral posted or held at December 31, 2018.

13. Acquisitions and Divestitures
During the six months ended June 30, 2019, EOG paid cash for property acquisitions of $304 million in the United States. Additionally, during the six months ended June 30, 2019, EOG recognized net gains on asset dispositions of $4 million and received proceeds of approximately $18 million. During the six months ended June 30, 2018, EOG recognized net losses on asset dispositions of $(21) million, primarily due to non-cash exchanges of unproved leasehold in New Mexico and Wyoming as well as the disposition of inventory and other assets, and received proceeds of approximately $8 million.
14. Leases
In the ordinary course of business, EOG enters into contracts for drilling, fracturing, compression, real estate and other services which contain equipment and other assets that meet the definition of a lease under ASU 2016-02. The lease term for these contracts, which includes any renewals at EOG's option that are reasonably certain to be exercised, ranges from one month to 30 years. ROU assets and related liabilities are recognized on commencement date on the Condensed Consolidated Balance Sheets based on future lease payments, discounted based on the rate implicit in the contract, if readily determinable, or EOG's incremental borrowing rate commensurate with the lease term of the contract. Contracts with lease terms less than 12 months are not recorded on the Condensed Consolidated Balance Sheets, but instead are disclosed as short-term lease cost.
EOG has elected not to separate non-lease components from all leases, excluding those for fracturing services, real estate and salt water disposal, as lease payments for these contracts contain significant non-lease components, such as labor and operating costs.
Lease costs are classified by the function of the ROU asset. The lease costs related to exploration and development activities are initially included in the Oil and Gas Properties line on the Condensed Consolidated Balance Sheets and subsequently accounted for in accordance with the Extractive Industries - Oil and Gas Topic of the Accounting Standards Codification. Variable lease cost represents costs incurred above the contractual minimum payments for operating and finance leases. The components of lease cost for the three month and six month periods ended June 30, 2019, were as follows (in millions):

PART I. FINANCIAL INFORMATION
ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF
FINANCIAL CONDITION AND RESULTS OF OPERATIONS
EOG RESOURCES, INC.
Overview
EOG Resources, Inc., together with its subsidiaries (collectively, EOG), is one of the largest independent (non-integrated) crude oil and natural gas companies in the United States with proved reserves in the United States, Trinidad and China. EOG operates under a consistent business and operational strategy that focuses predominantly on maximizing the rate of return on investment of capital by controlling operating and capital costs and maximizing reserve recoveries. Each prospective drilling location is evaluated by its estimated rate of return. This strategy is intended to enhance the generation of cash flow and earnings from each unit of production on a cost-effective basis, allowing EOG to deliver long-term production growth while maintaining a strong balance sheet. EOG implements its strategy primarily by emphasizing the drilling of internally generated prospects in order to find and develop low-cost reserves. Maintaining the lowest possible operating cost structure that is consistent with efficient, safe and environmentally responsible operations is also an important goal in the implementation of EOG's strategy.
United States. EOG's efforts to identify plays with large reserve potential have proven to be successful. EOG continues to drill numerous wells in large acreage plays, which in the aggregate have contributed substantially to, and are expected to continue to contribute substantially to, EOG's crude oil and liquids-rich natural gas production. EOG has placed an emphasis on applying its horizontal drilling and completion expertise to unconventional crude oil and liquids-rich reservoirs.
Crude oil, natural gas liquids (NGLs) and natural gas prices have been volatile, and this volatility is expected to continue. As a result of the many uncertainties associated with the world political environment, worldwide supplies of, and demand for, crude oil and condensate, NGLs and natural gas and the availability of other energy supplies, EOG is unable to predict what changes may occur in crude oil and condensate, NGLs, and natural gas prices in the future. The market prices of crude oil and condensate, NGLs and natural gas in 2019 will continue to impact the amount of cash generated from EOG's operating activities, which will in turn impact EOG's financial position and results of operations. For the first six months of 2019, the average U.S. New York Mercantile Exchange (NYMEX) crude oil and natural gas prices were $57.38 per barrel and $2.87 per million British thermal units (MMBtu), respectively, representing a decrease of 12% and an increase of 1%, respectively, from the average NYMEX prices for the same period in 2018. Market prices for NGLs are influenced by crude oil prices and the composition of NGL production, including ethane, propane and butane, among others. Based on its 2019 drilling and completion plans, EOG expects its 2019 total production and total crude oil production to increase as compared to 2018.
During the first half of 2019, EOG continued to focus on increasing drilling, completion and operating efficiencies gained in prior years. In addition, EOG continued to evaluate certain potential crude oil and liquids-rich natural gas exploration and development prospects and to look for opportunities to add drilling inventory through leasehold acquisitions, farm-ins, exchanges or tactical acquisitions. On a volumetric basis, as calculated using the ratio of 1.0 barrel of crude oil and condensate or NGLs to 6.0 thousand cubic feet of natural gas, crude oil and condensate and NGL production accounted for approximately 77% and 76% of EOG's United States production during the first half of 2019 and 2018, respectively. During the first half of 2019, EOG's drilling and completion activities occurred primarily in the Eagle Ford play, Delaware Basin play and Rocky Mountain area. EOG's major producing areas in the United States are in New Mexico, North Dakota, Texas and Wyoming.
Trinidad. In Trinidad, EOG continues to deliver natural gas under existing supply contracts. Several fields in the South East Coast Consortium (SECC) Block, Modified U(a) Block, Block 4(a), Modified U(b) Block, the Banyan Field and the Sercan Area have been developed and are producing natural gas which is sold to the National Gas Company of Trinidad and Tobago Limited and its subsidiary, and crude oil and condensate which is sold to Heritage Petroleum Company Limited. During the second half of 2019, EOG plans to drill three net wells.
Other International. In the Sichuan Basin, Sichuan Province, China, EOG drilled two wells in the first half of 2019 to complete the drilling program started in 2018. EOG completed one drilled uncompleted well from the 2018 drilling program in 2019. All natural gas produced from the Baijaochang Field is sold under a long-term contract to PetroChina.
EOG continues to evaluate other select crude oil and natural gas opportunities outside the United States, primarily by pursuing exploitation opportunities in countries where indigenous crude oil and natural gas reserves have been identified.

Capital Structure. One of management's key strategies is to maintain a strong balance sheet with a consistently below average debt-to-total capitalization ratio as compared to those in EOG's peer group. EOG's debt-to-total capitalization ratio was 20% at June 30, 2019 and 24% at December 31, 2018. As used in this calculation, total capitalization represents the sum of total current and long-term debt and total stockholders' equity.
On June 3, 2019, EOG repaid upon maturity the $900 million aggregate principal amount of its 5.625% Senior Notes due 2019.
On June 27, 2019, EOG entered into a new $2.0 billion senior unsecured Revolving Credit Agreement (New Facility) with domestic and foreign lenders. The New Facility replaces EOG's $2.0 billion senior unsecured Revolving Credit Agreement, dated as of July 21, 2015, which had a scheduled maturity date of July 21, 2020. The New Facility has a scheduled maturity date of June 27, 2024, and includes an option for EOG to extend, on up to two occasions, the term for successive one-year periods subject to certain terms and conditions. The New Facility (i) commits the Banks to provide advances up to an aggregate principal amount of $2.0 billion at any one time outstanding, with an option for EOG to request increases in the aggregate commitments to an amount not to exceed $3.0 billion, subject to certain terms and conditions, and (ii) includes a swingline subfacility and a letter of credit subfacility.
Effective January 1, 2019, EOG adopted the provisions of Accounting Standards Update (ASU) 2016-02, "Leases (Topic 842)" (ASU 2016-02). ASU 2016-02 and other related ASUs resulted in the recognition of right-of-use assets and related lease liabilities representing the obligation to make lease payments for certain lease transactions and the disclosure of additional leasing information. The adoption of ASU 2016-02 and other related ASUs resulted in a significant increase to assets and liabilities related to operating leases on the Condensed Consolidated Balance Sheet at June 30, 2019. Financial results prior to January 1, 2019, are unchanged. See Note 1 "Summary of Significant Accounting Policies" and Note 14 "Leases" to EOG's Condensed Consolidated Financial Statements in this Quarterly Report on Form 10-Q.
Total anticipated 2019 capital expenditures are estimated to range from approximately $6.1 billion to $6.5 billion, excluding acquisitions and non-cash transactions. The majority of 2019 expenditures will be focused on United States crude oil drilling activities. EOG has significant flexibility with respect to financing alternatives, including borrowings under its commercial paper program and other uncommitted credit facilities, bank borrowings, borrowings under its $2.0 billion senior unsecured revolving credit facility, joint development agreements and similar agreements and equity and debt offerings.
Management continues to believe EOG has one of the strongest prospect inventories in EOG's history. When it fits EOG's strategy, EOG will make acquisitions that bolster existing drilling programs or offer incremental exploration and/or production opportunities.

Wellhead crude oil and condensate revenues for the second quarter of 2019 increased $151 million, or 6%, to $2,529 million from $2,378 million for the same period of 2018. The increase was due to an increase of 71 MBbld, or 18%, in wellhead crude oil and condensate production ($439 million), partially offset by a lower composite average price ($288 million). Increased production was primarily due to increases in the Permian Basin and the Eagle Ford. EOG's composite wellhead crude oil and condensate price for the second quarter of 2019 decreased 10% to $60.99 per barrel compared to $67.93 per barrel for the same period of 2018.
NGL revenues for the second quarter of 2019 decreased $100 million, or 35%, to $186 million from $286 million for the same period of 2018 due to a lower composite average price ($146 million), partially offset by an increase of 18 MBbld, or 16%, in production ($46 million). Increased production was primarily in the Permian Basin. EOG's composite NGL price for the second quarter of 2019 decreased 44% to $15.63 per barrel compared to $27.86 per barrel for the same period of 2018.
Wellhead natural gas revenues for the second quarter of 2019 decreased $31 million, or 10%, to $270 million from $301 million for the same period of 2018. The decrease was due to a lower average composite price ($63 million), partially offset by an increase in natural gas deliveries ($32 million). Natural gas deliveries for the second quarter of 2019 increased 128 MMcfd, or 10%, compared to the same period of 2018 due primarily to higher deliveries in the United States primarily resulting from increased production of associated natural gas from the Permian Basin and higher natural gas volumes in South Texas. EOG's composite wellhead natural gas price for the second quarter of 2019 decreased 19% to $2.19 per Mcf compared to $2.69 per Mcf for the same period of 2018.
During the second quarter of 2019, EOG recognized net gains on the mark-to-market of financial commodity derivative contracts of $177 million compared to net losses of $186 million for the same period of 2018. During the second quarter of 2019, net cash received from settlements of financial commodity derivative contracts was $10 million compared to net cash paid of $66 million for the same period of 2018.
Gathering, processing and marketing revenues are revenues generated from sales of third-party crude oil, NGLs and natural gas, as well as gathering fees associated with gathering third-party natural gas and revenues from sales of EOG-owned sand. Purchases and sales of third-party crude oil and natural gas may be utilized in order to balance firm transportation capacity with production in certain areas and to utilize excess capacity at EOG-owned facilities. EOG sells sand in order to balance the timing of firm purchase agreements with completion operations and to utilize excess capacity at EOG-owned facilities. Marketing costs represent the costs to purchase third-party crude oil, natural gas and sand and the associated transportation costs, as well as costs associated with EOG-owned sand sold to third parties.
Gathering, processing and marketing revenues less marketing costs for the second quarter of 2019 decreased $15 million as compared to the same period of 2018 primarily due to lower margins on crude oil marketing activities, partially offset by higher margins on natural gas marketing activities.
Operating and Other Expenses. For the second quarter of 2019, operating expenses of $3,567 million were $294 million higher than the $3,273 million incurred during the second quarter of 2018. The following table presents the costs per barrel of oil equivalent (Boe) for the three-month periods ended June 30, 2019 and 2018:

| Three Months Ended June 30,
| 2019 |  | 2018

The primary factors impacting the cost components of per-unit rates of lease and well, transportation costs, DD&A, G&A and net interest expense for the three months ended June 30, 2019, compared to the same period of 2018, are set forth below. See "Operating Revenues" above for a discussion of wellhead volumes.
Lease and well expenses include expenses for EOG-operated properties, as well as expenses billed to EOG from other operators where EOG is not the operator of a property. Lease and well expenses can be divided into the following categories: costs to operate and maintain crude oil and natural gas wells, the cost of workovers and lease and well administrative expenses. Operating and maintenance costs include, among other things, pumping services, salt water disposal, equipment repair and maintenance, compression expense, lease upkeep and fuel and power. Workovers are operations to restore or maintain production from existing wells.
Each of these categories of costs individually fluctuates from time to time as EOG attempts to maintain and increase production while maintaining efficient, safe and environmentally responsible operations. EOG continues to increase its operating activities by drilling new wells in existing and new areas. Operating and maintenance costs within these existing and new areas, as well as the costs of services charged to EOG by vendors, fluctuate over time.
Lease and well expenses of $347 million for the second quarter of 2019 increased $32 million from $315 million for the same prior year period primarily due to increased operating and maintenance costs ($24 million), lease and well administrative expenses ($8 million) and workover expenditures ($4 million), all in the United States, partially offset by decreased operating and maintenance costs in the United Kingdom ($3 million) due to the sale of operations in the fourth quarter of 2018. Lease and well expenses increased in the United States primarily due to increased operating activities resulting in increased production.
Transportation costs represent costs associated with the delivery of hydrocarbon products from the lease to a downstream point of sale. Transportation costs include transportation fees, the cost of compression (the cost of compressing natural gas to meet pipeline pressure requirements), the cost of dehydration (the cost associated with removing water from natural gas to meet pipeline requirements), gathering fees and fuel costs.
Transportation costs of $174 million for the second quarter of 2019 decreased $4 million from $178 million for the same prior year period primarily due to decreased transportation costs in the Eagle Ford ($24 million), partially offset by increased transportation costs in the Permian Basin ($17 million) and Rocky Mountain area ($4 million).
DD&A of the cost of proved oil and gas properties is calculated using the unit-of-production method. EOG's DD&A rate and expense are the composite of numerous individual DD&A group calculations. There are several factors that can impact EOG's composite DD&A rate and expense, such as field production profiles, drilling or acquisition of new wells, disposition of existing wells and reserve revisions (upward or downward) primarily related to well performance, economic factors and impairments. Changes to these factors may cause EOG's composite DD&A rate and expense to fluctuate from period to period. DD&A of the cost of other property, plant and equipment is generally calculated using the straight-line depreciation method over the useful lives of the assets.
DD&A expenses for the second quarter of 2019 increased $108 million to $957 million from $849 million for the same prior year period. DD&A expenses associated with oil and gas properties for the second quarter of 2019 were $108 million higher than the same prior year period. The increase primarily reflects increased production in the United States.
G&A expenses of $122 million for the second quarter of 2019 increased $18 million from $104 million for the same prior year period primarily due to increased employee-related expenses resulting from expanded operations.
Interest expense, net of $50 million for the second quarter of 2019 decreased $14 million compared to the same prior year period primarily due to repayment in October 2018 of the $350 million aggregate principal amount of 6.875% Senior Notes due 2018 ($6 million), repayment in June 2019 of the $900 million aggregate principal amount of 5.625% Senior Notes due 2019 ($4 million) and higher capitalized interest ($4 million).
Exploration costs of $33 million for the second quarter of 2019 decreased $14 million from $47 million for the same prior year period primarily due to decreased geological and geophysical costs in Trinidad.

Impairments include amortization of unproved oil and gas property costs as well as impairments of proved oil and gas properties; other property, plant and equipment; and other assets. Unproved properties with acquisition costs that are not individually significant are aggregated, and the portion of such costs estimated to be nonproductive is amortized over the remaining lease term. Unproved properties with individually significant acquisition costs are reviewed individually for impairment. When circumstances indicate that a proved property may be impaired, EOG compares expected undiscounted future cash flows at a DD&A group level to the unamortized capitalized cost of the asset. If the expected undiscounted future cash flows are lower than the unamortized capitalized cost, the capitalized cost is reduced to fair value. Fair value is generally calculated by using the Income Approach described in the Fair Value Measurement Topic of the Financial Accounting Standards Board's Accounting Standards Codification. In certain instances, EOG utilizes accepted offers from third-party purchasers as the basis for determining fair value.
Impairments of $112 million for the second quarter of 2019 were $60 million higher than impairments for the same prior year period primarily due to increased impairments of other assets in the United States. EOG recorded impairments of proved properties, other property, plant and equipment and other assets of $65 million and $10 million for the second quarter of 2019 and 2018, respectively.
Taxes other than income include severance/production taxes, ad valorem/property taxes, payroll taxes, franchise taxes and other miscellaneous taxes. Severance/production taxes are generally determined based on wellhead revenues, and ad valorem/property taxes are generally determined based on the valuation of the underlying assets.
Taxes other than income for the second quarter of 2019 increased $10 million to $204 million (6.8% of wellhead revenues) compared to $194 million (6.6% of wellhead revenues) for the same prior year period. The increase in taxes other than income was primarily due to increased ad valorem/property taxes ($16 million) primarily as a result of increased valuation of the underlying assets, partially offset by decreases in severance/production taxes ($3 million), both in the United States, and an increase in credits available to EOG in the second quarter of 2019 for Texas high-cost gas severance tax rate reductions ($2 million).
Other income, net of $9 million for the second quarter of 2019 increased $17 million compared to the same prior year period primarily due to higher foreign currency exchange gains ($7 million), an increase in interest income ($6 million) and a decrease in deferred compensation expense ($5 million).
EOG recognized an income tax provision of $242 million for the second quarter of 2019 compared to an income tax provision of $196 million for the second quarter of 2018, primarily due to an increase in pretax income. The net effective tax rate of 22% for the second quarter of 2019 was unchanged from the second quarter of 2018.
Six Months Ended June 30, 2019 vs. Six Months Ended June 30, 2018
Operating Revenues. During the first six months of 2019, operating revenues increased $837 million, or 11%, to $8,756 million from $7,919 million for the same period of 2018. Total wellhead revenues for the first six months of 2019 increased $152 million, or 3%, to $5,739 million from $5,587 million for the same period of 2018. During the first six months of 2019, EOG recognized net gains on the mark-to-market of financial commodity derivative contracts of $157 million compared to net losses of $246 million for the same period of 2018. Gathering, processing and marketing revenues for the first six months of 2019 increased $249 million, or 10%, to $2,787 million from $2,538 million for the same period of 2018. Net gains on asset dispositions were $4 million for the first six months of 2019 compared to net losses of $21 million for the same period of 2018.

Wellhead crude oil and condensate revenues for the first six months of 2019 increased $250 million, or 6%, to $4,729 million from $4,479 million for the same period of 2018 due to an increase of 72 MBbld, or 19%, in wellhead crude oil and condensate production ($859 million), partially offset by a lower composite average price ($609 million). Increased production was primarily due to increases in the Permian Basin and the Eagle Ford. EOG's composite wellhead crude oil and condensate price for the first six months of 2019 decreased 11% to $58.61 per barrel compared to $66.16 per barrel for the same period of 2018.
NGL revenues for the first six months of 2019 decreased $103 million, or 20%, to $405 million from $508 million for the same period of 2018 due to a lower composite average price ($192 million), partially offset by an increase of 19 MBbld, or 17%, in NGL deliveries ($89 million). Increased production was primarily in the Permian Basin. EOG's composite NGL price for the first six months of 2019 decreased 32% to $17.84 per barrel compared to $26.27 per barrel for the same period of 2018.
Wellhead natural gas revenues for the first six months of 2019 increased $4 million, or 1%, to $605 million from $601 million for the same period of 2018. The increase was due to an increase in natural gas deliveries ($59 million), partially offset by a lower composite wellhead natural gas price ($55 million). Natural gas deliveries for the first six months of 2019 increased 130 MMcfd, or 11%, compared to the same period of 2018 due primarily to higher deliveries in the United States resulting from increased production of associated natural gas from the Permian Basin and higher natural gas volumes from South Texas, partially offset by lower production of associated natural gas in the Rocky Mountain area and lower natural gas deliveries in Trinidad. EOG's composite wellhead natural gas price for the first six months of 2019 decreased 9% to $2.51 per Mcf compared to $2.76 per Mcf for the same period of 2018.
During the first six months of 2019, EOG recognized net gains on the mark-to-market of financial commodity derivative contracts of $157 million compared to net losses of $246 million for the same period of 2018. During the first six months of 2019, net cash received from settlements of financial commodity derivative contracts was $31 million compared to net cash paid for settlements of financial commodity derivative contracts of $88 million for the same period of 2018.
Gathering, processing and marketing revenues less marketing costs for the first six months of 2019 increased $5 million as compared to the same period of 2018 primarily due to higher margins on natural gas marketing activities.
Operating and Other Expenses. For the first six months of 2019, operating expenses of $6,749 million were $669 million higher than the $6,080 million incurred during the same period of 2018. The following table presents the costs per Boe for the six-month periods ended June 30, 2019 and 2018:

Lease and well expenses of $684 million for the first six months of 2019 increased $69 million from $615 million for the same prior year period primarily due to higher operating and maintenance costs ($48 million), higher workover expenditures ($17 million) and higher lease and well administrative costs ($12 million), all in the United States, partially offset by lower operating and maintenance costs in the United Kingdom ($8 million) due to the sale of operations in the fourth quarter of 2018. Lease and well expenses increased in the United States primarily due to increased operating activities resulting in increased production.
-29-

Transportation costs of $351 million for the first six months of 2019 decreased $4 million from $355 million for the same prior year period primarily due to decreased transportation costs in the Eagle Ford ($40 million), partially offset by increased transportation costs in the Permian Basin ($38 million).
DD&A expenses for the first six months of 2019 increased $240 million to $1,837 million from $1,597 million for the same prior year period. DD&A expenses associated with oil and gas properties for the first six months of 2019 were $241 million higher than the same prior year period. The increase primarily reflects increased production in the United States.
G&A expenses of $228 million for the first six months of 2019 increased $29 million from $199 million for the same prior year period primarily due to increased employee-related expenses resulting from expanded operations.
Interest expense, net of $105 million for the first six months of 2019 decreased $21 million compared to the same prior year period primarily due to repayment in October 2018 of the $350 million aggregate principal amount of 6.875% Senior Notes due 2018 ($12 million), higher capitalized interest ($6 million) and repayment in June 2019 of the $900 million aggregate principal amount of 5.625% Senior Notes due 2019 ($4 million).
Gathering and processing costs represent operating and maintenance expenses and administrative expenses associated with operating EOG's gathering and processing assets as well as natural gas processing fees from third parties. EOG pays third parties to process the majority of its natural gas production to extract NGLs.
Gathering and processing costs of $224 million for the first six months of 2019 increased $13 million compared to the same prior year period primarily due to increased operating costs in the Permian Basin ($28 million) and the Rocky Mountain area ($5 million), partially offset by decreased operating costs in the United Kingdom ($19 million) due to the sale of operations in the fourth quarter of 2018.
Exploration costs of $69 million for the first six months of 2019 decreased $13 million from $82 million for the same prior year period primarily due to decreased geological and geophysical costs in Trinidad.
Impairments of $184 million for the first six months of 2019 were $68 million higher than impairments for the same prior year period primarily due to increased impairments of other assets in the United States. EOG recorded impairments of proved properties, other property, plant and equipment and other assets of $91 million and $32 million for the first six months of 2019 and 2018, respectively.
Taxes other than income for the first six months of 2019 increased $24 million to $397 million (6.9% of wellhead revenues) from $373 million (6.7% of wellhead revenues) for the same prior year period. The increase in taxes other than income was primarily due to increased ad valorem/property taxes in the United States ($37 million) primarily as a result of increased valuation of the underlying assets, partially offset by decreases in severance/production taxes in the United States ($6 million) and Trinidad ($3 million), and an increase in credits available to EOG in the second quarter of 2019 for Texas high-cost severance tax rate reductions ($4 million).
Other income, net of $14 million for the first six months of 2019 increased $22 million compared to the same prior year period primarily due to an increase in interest income ($11 million) and higher foreign currency exchange gains ($8 million).
EOG recognized an income tax provision of $433 million for the first six months of 2019 compared to an income tax provision of $371 million for the same period in 2018, primarily due to an increase in pretax income. The net effective tax rate for the first six months of 2019 increased to 23% from 22% for the first six months of 2018.

Capital Resources and Liquidity
Cash Flow. The primary sources of cash for EOG during the six months ended June 30, 2019, were funds generated from operations. The primary uses of cash were funds used in operations; exploration and development expenditures; long-term debt repayments; dividend payments to stockholders; and other property, plant and equipment expenditures. During the first six months of 2019, EOG's cash balance decreased $396 million to $1,160 million from $1,556 million at December 31, 2018.
Net cash provided by operating activities of $4,294 million for the first six months of 2019 increased $801 million compared to the same period of 2018 primarily due to a decrease in net cash paid for income taxes ($395 million), a favorable change in working capital ($252 million), an increase in wellhead revenues ($152 million) and an increase in cash received for settlements of commodity derivative contracts ($120 million), partially offset by an increase in cash operating expenses ($104 million).
Net cash used in investing activities of $3,524 million for the first six months of 2019 increased by $434 million compared to the same period of 2018 due to an increase in additions to oil and gas properties ($466 million) and an unfavorable change in components of working capital associated with investing activities ($5 million), partially offset by a decrease in additions to other property, plant and equipment ($28 million) and an increase in proceeds from the sale of assets ($9 million).
Net cash used in financing activities of $1,166 million for the first six months of 2019 included repayments of long-term debt ($900 million) and cash dividend payments ($255 million). Net cash used in financing activities of $228 million for the first six months of 2018 included cash dividend payments ($204 million) and purchases of treasury stock in connection with stock compensation plans ($32 million).
Total Expenditures. For the year 2019, EOG's budget for exploration and development and other property, plant and equipment expenditures is approximately $6.1 billion to $6.5 billion, excluding acquisitions and non-cash transactions. The table below sets out components of total expenditures for the six-month periods ended June 30, 2019 and 2018 (in millions):

| Six Months Ended June 30,
| 2019 |  | 2018
Expenditure Category |  |  |
Capital |  |  |
Exploration and Development Drilling | $ | 2,692 |  |  | $ | 2,503 |
Facilities | 338 |  |  | 340 |
Leasehold Acquisitions (1) | 145 |  |  | 172 |
Property Acquisitions (2) | 322 |  |  | 37 |
Capitalized Interest | 18 |  |  | 11 |
Subtotal | 3,515 |  |  | 3,063 |
Exploration Costs | 69 |  |  | 82 |
Dry Hole Costs | 4 |  |  | 5 |
Exploration and Development Expenditures | 3,588 |  |  | 3,150 |
Asset Retirement Costs | 60 |  |  | 31 |
Total Exploration and Development Expenditures | 3,648 |  |  | 3,181 |
Other Property, Plant and Equipment (3) | 117 |  |  | 193 |
Total Expenditures | $ | 3,765 |  |  | $ | 3,374 |

(1) | Leasehold acquisitions included $54 million and $60 million for the six-month periods ended June 30, 2019 and 2018, respectively, related to non-cash property exchanges.

(2) | Property acquisitions included $18 million and $23 million for the six-month periods ended June 30, 2019 and 2018, respectively, related to non-cash property exchanges.

(3) | Other property, plant and equipment included $48 million of non-cash additions for the six-month period ended June 30, 2018 made in connection with a finance lease transaction in the Permian Basin.

-31-

Exploration and development expenditures of $3,588 million for the first six months of 2019 were $438 million higher than the same period of 2018 primarily due to increased property acquisitions ($285 million) and increased exploration and drilling expenditures in the United States ($181 million), partially offset by decreased leasehold acquisitions ($27 million). Exploration and development expenditures for the first six months of 2019 of $3,588 million consisted of $3,010 million in development drilling and facilities, $322 million in property acquisitions, $238 million in exploration and $18 million in capitalized interest. Exploration and development expenditures for the first six months of 2018 of $3,150 million consisted of $2,839 million in development drilling and facilities, $263 million in exploration, $37 million in property acquisitions and $11 million in capitalized interest.
The level of exploration and development expenditures, including acquisitions, will vary in future periods depending on energy market conditions and other economic factors. EOG has significant flexibility with respect to financing alternatives and the ability to adjust its exploration and development expenditure budget as circumstances warrant. While EOG has certain continuing commitments associated with expenditure plans related to its operations, such commitments are not expected to be material when considered in relation to the total financial capacity of EOG.
Commodity Derivative Transactions. As more fully discussed in Note 12 to the Consolidated Financial Statements included in EOG's Annual Report on Form 10-K for the year ended December 31, 2018, filed on February 26, 2019, EOG engages in price risk management activities from time to time. These activities are intended to manage EOG's exposure to fluctuations in commodity prices for crude oil and natural gas. EOG utilizes financial commodity derivative instruments, primarily price swap, option, swaption, collar and basis swap contracts, as a means to manage this price risk. EOG has not designated any of its financial commodity derivative contracts as accounting hedges and, accordingly, accounts for financial commodity derivative contracts using the mark-to-market accounting method. Under this accounting method, changes in the fair value of outstanding financial instruments are recognized as gains or losses in the period of change and are recorded as Gains (Losses) on Mark-to-Market Commodity Derivative Contracts on the Condensed Consolidated Statements of Income and Comprehensive Income. The related cash flow impact is reflected in Cash Flows from Operating Activities on the Condensed Consolidated Statements of Cash Flows.
The total fair value of EOG's commodity derivative contracts was reflected on the Condensed Consolidated Balance Sheets at June 30, 2019, as a net asset of $135 million.
Prices received by EOG for its crude oil production generally vary from NYMEX West Texas Intermediate prices due to adjustments for delivery location (basis) and other factors. EOG has entered into crude oil basis swap contracts in order to fix the differential between pricing in Midland, Texas, and Cushing, Oklahoma (Midland Differential). Presented below is a comprehensive summary of EOG's Midland Differential basis swap contracts through July 29, 2019. The weighted average price differential expressed in dollars per barrel ($/Bbl) represents the amount of reduction to Cushing, Oklahoma, prices for the notional volumes expressed in barrels per day (Bbld) covered by the basis swap contracts.

| Midland Differential Basis Swap Contracts
|  |  | Volume (Bbld) |  | Weighted Average Price Differential ($/Bbl)
| 2019 |  |  |  |
| January 1, 2019 through August 31, 2019 (closed) |  | 20,000 |  |  | $ | 1.075 |
| September 1, 2019 through December 31, 2019 |  | 20,000 |  |  | 1.075 |

EOG has also entered into crude oil basis swap contracts in order to fix the differential between pricing in the U.S. Gulf Coast and Cushing, Oklahoma (Gulf Coast Differential). Presented below is a comprehensive summary of EOG's Gulf Coast Differential basis swap contracts through July 29, 2019. The weighted average price differential expressed in $/Bbl represents the amount of addition to Cushing, Oklahoma, prices for the notional volumes expressed in Bbld covered by the basis swap contracts.

Information Regarding Forward-Looking Statements
This Quarterly Report on Form 10-Q includes forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. All statements, other than statements of historical facts, including, among others, statements and projections regarding EOG's future financial position, operations, performance, business strategy, returns, budgets, reserves, levels of production, capital expenditures, costs and asset sales, statements regarding future commodity prices and statements regarding the plans and objectives of EOG's management for future operations, are forward-looking statements. EOG typically uses words such as "expect," "anticipate," "estimate," "project," "strategy," "intend," "plan," "target," "aims," "goal," "may," "will," "should" and "believe" or the negative of those terms or other variations or comparable terminology to identify its forward-looking statements. In particular, statements, express or implied, concerning EOG's future operating results and returns or EOG's ability to replace or increase reserves, increase production, generate returns, replace or increase drilling locations, reduce or otherwise control operating costs and capital expenditures, generate cash flows, pay down or refinance indebtedness or pay and/or increase dividends are forward-looking statements. Forward-looking statements are not guarantees of performance. Although EOG believes the expectations reflected in its forward-looking statements are reasonable and are based on reasonable assumptions, no assurance can be given that these assumptions are accurate or that any of these expectations will be achieved (in full or at all) or will prove to have been correct. Moreover, EOG's forward-looking statements may be affected by known, unknown or currently unforeseen risks, events or circumstances that may be outside EOG's control. Important factors that could cause EOG's actual results to differ materially from the expectations reflected in EOG's forward-looking statements include, among others:

• | the timing, extent and duration of changes in prices for, supplies of, and demand for, crude oil and condensate, natural gas liquids, natural gas and related commodities;

• | the extent to which EOG is successful in its efforts to acquire or discover additional reserves;

• | the extent to which EOG is successful in its efforts to economically develop its acreage in, produce reserves and achieve anticipated production levels from, and maximize reserve recovery from, its existing and future crude oil and natural gas exploration and development projects;

• | the extent to which EOG is successful in its efforts to market its crude oil and condensate, natural gas liquids, natural gas and related commodity production;

• | the availability, proximity and capacity of, and costs associated with, appropriate gathering, processing, compression, storage, transportation and refining facilities;

• | the availability, cost, terms and timing of issuance or execution of, and competition for, mineral licenses and leases and governmental and other permits and rights-of-way, and EOG’s ability to retain mineral licenses and leases;

• | the impact of, and changes in, government policies, laws and regulations, including tax laws and regulations; climate change and other environmental, health and safety laws and regulations relating to air emissions, disposal of produced water, drilling fluids and other wastes, hydraulic fracturing and access to and use of water; laws and regulations imposing conditions or restrictions on drilling and completion operations and on the transportation of crude oil and natural gas; laws and regulations with respect to derivatives and hedging activities; and laws and regulations with respect to the import and export of crude oil, natural gas and related commodities;

• | EOG's ability to effectively integrate acquired crude oil and natural gas properties into its operations, fully identify existing and potential problems with respect to such properties and accurately estimate reserves, production and costs with respect to such properties;

• | the extent to which EOG's third-party-operated crude oil and natural gas properties are operated successfully and economically;

• | competition in the oil and gas exploration and production industry for the acquisition of licenses, leases and properties, employees and other personnel, facilities, equipment, materials and services;

• | the availability and cost of employees and other personnel, facilities, equipment, materials (such as water and tubulars) and services;

• | the accuracy of reserve estimates, which by their nature involve the exercise of professional judgment and may therefore be imprecise;

• | weather, including its impact on crude oil and natural gas demand, and weather-related delays in drilling and in the installation and operation (by EOG or third parties) of production, gathering, processing, refining, compression, storage and transportation facilities;

• | the ability of EOG's customers and other contractual counterparties to satisfy their obligations to EOG and, related thereto, to access the credit and capital markets to obtain financing needed to satisfy their obligations to EOG;

• | EOG's ability to access the commercial paper market and other credit and capital markets to obtain financing on terms it deems acceptable, if at all, and to otherwise satisfy its capital expenditure requirements;

• | the extent to which EOG is successful in its completion of planned asset dispositions;

• | the extent and effect of any hedging activities engaged in by EOG;

-34-

• | the timing and extent of changes in foreign currency exchange rates, interest rates, inflation rates, global and domestic financial market conditions and global and domestic general economic conditions;

• | geopolitical factors and political conditions and developments around the world (such as the imposition of tariffs or trade or other economic sanctions, political instability and armed conflict), including in the areas in which EOG operates;

• | the use of competing energy sources and the development of alternative energy sources;

• | the extent to which EOG incurs uninsured losses and liabilities or losses and liabilities in excess of its insurance coverage;

• | acts of war and terrorism and responses to these acts;

• | physical, electronic and cybersecurity breaches; and

• | the other factors described under ITEM 1A, Risk Factors, on pages 13 through 22 of EOG's Annual Report on Form 10-K for the fiscal year ended December 31, 2018, and any updates to those factors set forth in EOG's subsequent Quarterly Reports on Form 10-Q or Current Reports on Form 8-K.

In light of these risks, uncertainties and assumptions, the events anticipated by EOG's forward-looking statements may not occur, and, if any of such events do, we may not have anticipated the timing of their occurrence or the duration or extent of their impact on our actual results. Accordingly, you should not place any undue reliance on any of EOG's forward-looking statements. EOG's forward-looking statements speak only as of the date made, and EOG undertakes no obligation, other than as required by applicable law, to update or revise its forward-looking statements, whether as a result of new information, subsequent events, anticipated or unanticipated circumstances or otherwise.
