Conoco Inc.'s fracture assisted steamflood technology (fast) has boosted recovery of heavy oil from shallow zones in Loco Field in Stephens County, Oklahoma to 25 to 50% from approxmately 3%. The company plans to use the fast process to increase recovery from Loco's deeper zones to 40% from 7%. In addition, Conoco expects to license the process for use in heavy oil deposits in Texas, Utah, and Wyoming and the Athabasca tar sands in Alberta. Since the Loco Pilot Project went on stream in 1974, Conoco has run 20 fast injection well patterns which boosted recovery by 25 to 50% from pay at 50 to 350 ft. The first fast test at Loco yielded 43,000 bbl of oil in 6 months, or 60% of the trial zones oil in place. Conoco pegs Loco Fields's shallow oil in place at approximately 70 million bbl with a gravity of approximately 23 to 24. Plans call for the fast process to be used to recover an additional 40%, or approximately 30 million bbl of 26 g oil, from Loco's deeper zones at 1000 to 1200 ft. Tests showed fast recovery feasible at 1500 ft and shallower depths.
