AbstractIn the northern part of Erzhong District in Karamay conglomerate oilfield, Xinjiang, China, ASP pilot tests have been conducted in 13 wells in a pilot area of 0.031 square kilometers since September 1994. The pilot area was developed through combining laboratory results in recent years with specific conditions in the field. This testis aimed to verify oil displacement eficiency of ASP and related reservoir behaviors, to improve production techniques necessary to obtain remaining oil from conglomerate reservoirs, and to provide data for economic feasibility evaluation.
