Crude Oil Characteristics Crude oils are blends of hydrocarbon molecules Classified and priced by density, sulfur content, and acidity Density is commonly measured in API gravity (relative density of crude oil to water) API > 10: lighter, floats on water API < 10: heavier, sinks in water Sulfur content is measured in weight percent Less than 0.7% sulfur content = sweet Greater than 0.7% sulfur content = sour Acidity is measured by Total Acid Number (TAN) High acid crudes are those with TAN greater than 0.7 Acidic crudes are corrosive to refinery equipment, require greater investment to process significant volumes or higher TAN levels Higher API crudes generally have lower sulfur and are easier to process whereas lower API crudes typically have higher sulfur and require additional downstream processing to produce fuels that meet regulatory specs 5 Heavier, higher sulfur, more acidic crudes tend to trade at discounts relative to the light, sweet, low TAN benchmarks WTI, Brent, or LLS (unless logistically constrained)

Maximizing Refinery Profit Relationship between variables modeled in series of linear equations Linear program used to find combination of feed and product slates, operating rates and parameters that delivers highest profit 17 Prices Qualities Availabilities (purchase volumes) Prices Specifications Market demand (sales volumes) 10 - 25+ individual process units Unit hardware constraints Operating parameters (severity/conversion, cutpoints, stream disposition) Operating costs (energy, catalysts, process chemicals) Refinery Feedstocks (100+) Products (30+)

Growth in Light Sweet Crude Oil Production Is Changing How Refineries Are Optimized Growing supply of domestic light sweet crude is outpacing demand closest to areas where the crude is produced New pipeline capacity and rail facilities are enabling the movement of inland crude to coastal refineries Crude supply length in the USGC is leading to structural discounts for light sweet crudes and incentivizing refiners to process increasing volumes Refiners pursue no-capital options first to optimize crude slate Back out foreign imports from existing light sweet capacity Fill previously uneconomic light crude capacity Displace less economic, heavier crude oil from the feed slate 18

Growth in Light Sweet Crude Oil Production Is Changing How Refineries Are Optimized Refinery configuration plays a large part in determining the suitability of crudes and feedstocks Each refinery is designed to process a specific range of feedstocks Otherwise construction costs would be prohibitively high to accommodate all types Running feedstocks that fall outside of that range may cause constraints to be hit before the design capacity is reached Refiners optimize between maximum rates and maximum profit LP models are used to make crude and feedstock selection decisions based on the relative economics of the available options 19

Further Optimization Requires Capital Investment Capital investments are evaluated for further increases in light crude runs Dependent on medium and long range views for crude pricing Logistics projects require relatively short time frame to permit, engineer, and construct; generally have high return and quick payout Refinery projects require more time to permit, design, and construct; have greater exposure to changing market fundamentals between project initiation and completion Refinery debottlenecks vary in scope and may require multiple constraints to be relieved in the crude unit and/or in downstream units Capital costs can range from $10 million to hundreds of millions, and projects can take months to years to implement 20

Examples of Constraints on Light Crude Runs Distillation tower unable to handle increased vapor traffic from light components Distillation column overhead hydraulic capacity limitations Furnace or heat exchanger design limits turndown flexibility or ability to cool and condense higher volume of light ends Saturated gas plant has insufficient capacity to process additional volume Downstream unit capacities limit volume of intermediates that can be converted into finished products 21

Challenges with Processing Light Crudes Light crudes contain significantly more naphtha and lighter components Bottleneck at top of crude distillation tower or in downstream naphtha and light ends processing units Disposition for incremental straight run gasoline and naphtha production needs to be addressed Crudes are not all created equal; generalizations about crude oil properties and product yield profiles are not necessarily applicable Some light crudes are inherently diesel-rich or gasoline-rich despite having a similar API gravities As Valero's diet shifted to higher API domestic shale crudes (Eagle Ford, Bakken), distillate yields have stayed about the same 22 Gasoline (high octane) Distillation Tower (Crude Unit) Propane, Butane, and lighter hydrocarbons Refinery fuel gas Propane NGLs < 90°F 90-220°F 220-315°F More Intermediates Final Products processing More processing C1 to C4 C5 to C8 C8 to C12 Gasoline (high octane) Jet fuel Straight Run Gasoline (low octane) Naphtha

27 Appendix

28 Major Refining Processes - Crude Processing Definition Separating crude oil into different hydrocarbon groups The most common means is through distillation Process Desalting - Prior to distillation, crude oil is often desalted to remove corrosive salts as well as metals and other suspended solids. Atmospheric Distillation - Used to separate the desalted crude into specific hydrocarbon groups (straight run gasoline, naphtha, light gas oil, etc.) or fractions. Vacuum Distillation - Heavy crude residue ("bottoms") from the atmospheric column is further separated using a lower-pressure distillation process. Means to lower the boiling points of the fractions and permit separation at lower temperatures, without decomposition and excessive coke formation.

Major Refining Processes - Cracking Definition "Cracking" or breaking down large, heavy hydrocarbon molecules into smaller hydrocarbon molecules through application of heat (thermal) or the use of catalysts Process Coking - Thermal non-catalytic cracking process that converts low value oils to higher value gasoline, gas oils and marketable coke. Residual fuel oil from vacuum distillation column is typical feedstock. Visbreaking - Thermal non-catalytic process used to convert large hydrocarbon molecules in heavy feedstocks to lighter products such as fuel gas, gasoline, naphtha and gas oil. Produces sufficient middle distillates to reduce the viscosity of the heavy feed. Catalytic Cracking - A central process in refining where heavy gas oil range feeds are subjected to heat in the presence of catalyst and large molecules crack into smaller molecules in the gasoline and lighter boiling ranges. Catalytic Hydrocracking - Like cracking, used to produce blending stocks for gasoline and other fuels from heavy feedstocks. Introduction of hydrogen in addition to a catalyst allows the cracking reaction to proceed at lower temperatures than in catalytic cracking, although pressures are much higher. 29

30 Major Refining Processes - Combination Definition Linking two or more hydrocarbon molecules together to form a large molecule (e.g. converting gases to liquids) or rearranging to improve the quality of the molecule Process Alkylation - Important process to upgrade light olefins to high-value gasoline components. Used to combine small molecules into large molecules to produce a higher octane product for blending into gasoline. Catalytic Reforming - The process whereby naphthas are changed chemically to increase their octane numbers. Octane numbers are measures of whether a gasoline will knock in an engine. The higher the octane number, the more resistance to pre or self-ignition. Polymerization - Process that combines smaller molecules to produce high octane blendstock. Isomerization - Process used to produce compounds with high octane for blending into the gasoline pool. Also used to produce isobutene, an important feedstock for alkylation.

31 Major Refining Processes - Treating Definition Processing of petroleum products to remove some of the sulfur, nitrogen, heavy metals, and other impurities Process Catalytic Hydrotreating, Hydroprocessing, sulfur/metals removal - Used to remove impurities (e.g. sulfur, nitrogen, oxygen and halides) from petroleum fractions. Hydrotreating further "upgrades" heavy feeds by converting olefins and diolefins to paraffins, which reduces gum formation in fuels. Hydroprocessing also cracks heavier products to lighter, more saleable products.
