This study discusses the initiation and performance of a shallow zone steam-flood project in the Loco field, Stephens County, Oklahoma. The flood has been conducted in 2 thin Permian sands, at depths of 200 ft and 500 ft. The zones are 18 ft and 12 ft thick, respectively. Each sand is 74% oil saturated and has negligible gas saturation. At reservoir conditions, the oil viscosity is over 798 cSt in the 200-ft zone and 254 cSt in the 500-ft zone. The heavy 20' API oil is immobile under natural conditions and earlier enhanced recovery projects have proven unsuccessful. Results indicate that steam flooding in the Loco field is mechanically feasible. Oil recovery from steam flooding has been 90,500 bbl or 645 bbl of oil per acre-ft. This represents an average pattern recovery of 46.4% of the original oil in place. The cumulative producing water/oil ratio was 4.77 to 1.
