Karachaganak Oil and Gas Field

Operator: ENI
Country: Kazakhstan
Location: Western Kazakhstan
Production start:
Partners: ENI SpA (29.25%), Shell plc (29.25%), Chevron (18%), Lukoil (13.5%) and KazMunaiGas (10%)
Type: Oil / Gas
Estimated Reserves: 5 bboe
Production Volume: In 2010, production of the Karachaganak field averaged 228 kbbl/d of liquids and 812 mmcf/d of natural gas

Situated onshore in the western part of the country, Karachaganak is a giant onshore hydrocarbon deposit that produces oil, condensate and natural gas, with recoverable reserves estimated at 5 billion boe.
The operations carried out by the Karachaganak Petroleum Operating BV (KPO) consortium are regulated by a 40-year Production Sharing Agreement that expires in 2037.
Oil is exported via the Caspian Pipeline Consortium Oil Pipeline
Some of the gas is re-injected and some sold to Gazprom in Russia. It is transported by the Karachaganak Orenburg Transportation System (KOTS) and is processed at the Orenburg Gas Processing Plant which is 130 kilometers away.
The KPC Gas De-bottlenecking (KGDBN) project aimed at increasing the overall KPC gas processing by expanding the gas handling capacity
In addition, the 4th Gas Reinjection Compressor (4IC) project increased the annual daily average volume of gas re-injected into the reservoir and to improve reservoir pressure support and the 5th Trunkline and Gas Reinjection Wells Projects upgrades the injection network capacity downstream of Unit 2 through installation of a new trunk line, and drilling and completion of new gas injection wells.

Approximately two-thirds of the liquids produced are stabilised at the Karachaganak Processing Complex (KPC) – with a capacity of over 150,000 barrels/day – before they are sent to western markets through the Caspian Pipeline Consortium Oil Pipeline and, since 2006, also through the Atyrau-Samara pipeline, which is connected to the Russian export system. The non-stabilised liquids and the gas that is not re-injected into the deposits are sold on the local Russian market through the Orenburg terminal.
