摘要

In 2000,Nations Energy Company initiated Cold Heavy Oil Production with Sand(CHOPS)in new areas on the flanks of the developed central part of Karazhanbas Field(also called Karazhanbasmunai-or"KBM"),a giant,shallow heavy oil field in western Kazakhstan.Progressive Cavity Pumps(PCPs)are used to lift the oil,and sand is allowed to enter perforated zones.Production of 38,000 bpd was reached by January 2004,an increase of over 25,000 bpd within four years.Sand flux is far lower than in Canadian cases because of the field's lower oil viscosities;water flux is higher due to higher water mobility and active flank water.
