Estimates are given of the production potential from thermal recovery methods, miscible and immiscible gas flooding, and chemical flooding methods. It was assumed that existing EOR technology is conventionally applied requiring a 10% real after tax rate of return similar to that assumed for conventional recovery method. Five alternative price paths for world supplies of crude oil were investigated. Supply possibilities from these enhanced methods are estimated as 0.9 million bbl/d in 1985 and show no variation despite the $6 range in price among the scenarios. By 1995, price increases have an impact as EOR production ranges from 1.3 to 1.7 million bbl/d; this range is almost entirely due to the price response seen in gas flooding (carbon dioxide flooding). Production rates for gas flooding vary from 0.2 million bbl/d in the low price case to 0.5 million bbl/d in the highest price case. In thermal production, most of the shallow, heavy oil resource base in California appears to be economically producible at the lower price path analyzed in the ARC which has a constant $15/bbl world oil price (1978 dollars) through 1992 then increases to $16.50/bbl in 1995. This category contributes between 0.9 and 1.1 million bbl/d during the 1985-1995 time frame. In thermal recovery, production from steam drive peaks around 1990, but the decline is partially offset by production from in situ processes. Chemical flooding appears to hold very little promise in the period from 1985-1995, adding a maximum of 120,000 bbl/d in 1995. Although thermal recovery techniques provide the bulk of production in the 1985-1995, they should decline in importance over time, providing 52 to 57% of ultimate recovery. Gas flooding will increase production over time to account for 37 to 41% of ultimate recovery and chemical flooding accounts for 6 to 7%.
