AbstractThe wells in the Kenkiak Under-Saltdome (KUS) oilfield in Kazakhstan are difficult to drill and complete due to the complicated geological conditions. Historically, among 42 wells which had been drilled in this area 40 wells were abandoned; only 2 wells are in production. The wells were completed by casing perforation, with low averaged daily rate of production 64 tons per well. After 1997, initially, wells were continuously completed by casing perforation, with averaged daily rate of production around 100 tons per well.
