ABOUT US
Buzachi Operating Ltd. is a joint venture oil and gas company operating the North Buzachi oil field on Kazakhstan’s Buzachi Peninsula. Formed in 2004, it is equally owned by China National Petroleum Corporation (CNPC) and Sinopec. The North Buzachi field, discovered in 1975, contains heavy, high-sulfur crude oil located 300–550 meters below the surface. This shallow depth facilitates cost-effective directional drilling and water-flooding programs. Production peaked in 2012 at approximately 40,000 barrels per day and currently averages around 20,000 barrels per day, , accounting for about 1% of Kazakhstan’s daily oil output.
As of 2021, the field had an estimated 50 million barrels of remaining recoverable reserves, supporting operations projected until at least 2054. Crude oil from the field is transported via heated pipelines to the port city of Aktau, where it enters the Caspian export system. Associated gas is partially reinjected into the reservoir and partially sold for regional power generation. While Buzachi Operating Ltd. does not own refining facilities, it markets untreated crude under long-term contracts to domestic and international processors.
The company employs approximately 900 staff, primarily from local communities, and invests in vocational training, road repairs, and health clinics through a voluntary social investment plan. Environmental management is guided by ISO 14001-certified procedures. In January 2025, the company was fined ₸8.4 billion for excessive gas flaring, leading to the installation of advanced vapor-recovery units. Waste materials, including drill cuttings and oil sludge, are managed under long-term contracts with licensed recyclers.
Buzachi Operating Ltd. continues to implement enhanced oil recovery techniques, such as polymer flooding and digital well surveillance, to extend the field's productive life while reducing its carbon footprint. The company's board meets quarterly in Aktau to review performance and strategic planning.
