EOR methods help ultimate recovery

US oil production by enhanced recovery methods was surveyed to determine who is using what methods, where they are being used, and how successful they have been. Results show that enhanced recovery methods produce 4.5% (385,071 bpd) of the total daily US production. The steam share of total enhanced recovery production reported totals 77% (approximately 296,000 bpd). Carbon dioxide and other gases help to produce 74,807 bpd, 19% of the reported enhanced recovery production. The survey shows that active and planned chemical tests have decreased, and that both thermal and gaseous methods are increasing in use. There are more companies adopting enhanced recovery methods, and such projects in Canada are at an all-time high. More money is going into joint company/US Department of Energy tests on enhanced recovery than in 1978. The survey report shows map sites of enhanced recovery projects (both active and planned), and lists projects by type, location, operator, starting date, area involved, number of wells, pay zone, porosity, permeability, depth, oil characteristics, previous production method, residual oil saturation, project maturity, total production, enhanced production, project evaluation, and profits.
