3.4 Petroleum Fuels
Diesel and LPG are produced from crude oil. These fuels, along with gasoline and other refinery products, share the same crude oil feedstock and therefore the same extraction and feedstock distribution paths (LPG, however, can also be produced from natural gas). Table 3-5 summarizes the 8 phases for conversion of crude oil to diesel and reformulated diesel.

3.4.1 Crude Oil Extraction
Crude oil for refineries in the SoCAB is produced from offshore and underground wells in the southern coast and San Joaquin Valley. Heavy crude from Kern County represents a large share of this product. Oil is also imported by tanker from Alaska and overseas. Table 3-6 shows the assumptions used for geographically allocating emissions to petroleum extraction and transport.
