THE DYNAMIC OF SUPPLY, DEMAND, AND COMPETITION<br />

2. U.S. refineries have adopted more efficient technologies and business<br />

methods.<br />

U.S. refiners have found processing methods that broaden the range of crude oils that<br />

they can process and allow them to produce more refined product for each barrel of crude<br />

processed. In addition, they have lowered inventory holdings, thereby lowering inventory costs.<br />

a. Downstream processing units have increased refineries’ abilities<br />

to process different kinds of crude and produce more high-value<br />

refined product for each barrel of crude processed.<br />

One way to assess a refiner’s capacity is to measure its capability to process crude oil by<br />

atmospheric distillation, which involves the separation of crude oil fractions by heating and<br />

cooling. This is the most basic and least sophisticated of refinery processes. The capacity of a<br />

refinery’s downstream processing units, which break down, build up, or otherwise treat the<br />

hydrocarbon molecules in crude oil, also influences a refinery’s production capabilities,<br />

however. Nearly all refineries have both atmospheric distillation and downstream processing<br />

units.<br />

Downstream processing units enable a refinery to use a wider array of crude oils,<br />

including lower-quality, lower-priced crude oil. For example, new technology in downstream<br />

processing has given some refineries the ability to make high-value products from sour crude. 41<br />

This enlarges the universe of potential crude oil suppliers. 42 In addition, increased downstream<br />

capabilities generally allow refiners to make a greater amount of higher-valued products, such as<br />

gasoline, from a given barrel of crude oil. Downstream technology also has allowed refiners to<br />

make a broader variety of refined products, including gasoline with more demanding<br />

environmental specifications.<br />

The downstream capabilities of U.S. refineries have increased significantly since the<br />

1980s. For example, Figure 3-8 shows that between 1997 and 2004, total industry downstream<br />

charge capacity increased from 31.6 million barrels per day to 35.9 million barrels per day, an<br />

increase of 6.3 percent. 43 Consumer demand for products such as gasoline and diesel has<br />

motivated investment in downstream processes that can increase the yield of these products from<br />

a given barrel of crude. Downstream processing units also have been important in allowing<br />

refineries to comply with new environmental regulations, as discussed in Section (IV)(B) infra.<br />

Other technological improvements also have permitted refinery operating costs to decrease. 44<br />
