The article presents information on Cold Heavy Oil Production with Sand (CHOPS) production technology being used by Nations Energy Co. in 2000. CHOPS was initiated in new areas on the flanks of the developed central part of Karazhanbas Field (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. CHOPS is an economic success at KBM, allowing recovery factors of 8-15% from zones as thin as 10-33 ft, for which thermal technologies are not economically viable.
