A large onshore gas-oil-condensate field, the Karachaganak Field is located in northwest Kazakhstan near the city of Aksai, north of the Caspian Sea and south of the Russian border near Orenburg. Reserves in the field are estimated at 1.2 billion tons (8 billion barrels) of oil and gas condensate and 1.35 trillion cubic meters (48 trillion cubic feet) of gas. The KPO consortium – consisting of BG Group, Eni, ChevronTexaco and LUKOIL - has a production sharing agreement with the Kazakh government to enhance production, which in 2001 totaled 3.75 billion cubic meters of gas and 4 million tons of condensate.
The operation is being carried out by BJ PPS personnel, with the support of local staff in Aksai, Baku and Jebel Ali. The three-year contract, which includes two one-year extensions, has an estimated value in excess of US$8 million.
BJ PPS has already begun work under the contract for KPO. “By maintaining a large fleet of equipment in Kazakhstan, we have reduced mobilization costs and time to ensure the contract commenced on time,” said Lindsay Link, general manager of BJ PPS. “In addition to equipment we have modified to withstand harsh winter conditions in the Aksai region, we use high-flow 360,000 scfh nitrogen pumps and large capacity bulk nitrogen storage tankers. As a result, we have succeeded in purging systems both in and out of service, quickly and efficiently. Drawing upon our extensive experience in process services and patented state-of-the-art testing systems, we look forward to safely and effectively accelerating the shutdown process for KPO and ensuring a leak free start-up,” he added.
BJ has been involved with the Karachaganak Field Development Project since the initial construction and commissioning of the plant in 2002. BJ PPS personnel provided nitrogen and helium leak detection testing, and lube oil-flushing services for the company's process facilities, Unit 2 and the Karachaganak Processing Complex (KPC). BJ personnel from the company’s Europe and Africa Region also provided coiled tubing, nitrogen and stimulation services at the well sites that feed the KPO plant.
