Karachaganak Field

Karachaganak Field is a gas condensate field about 23 kilometres (14 mi) east of Aksay (Ақсай) in northwest Kazakhstan. It was once a massive Permian and Carboniferous reef complex covering an area 30 by 15 square kilometres. At its largest point, the reservoir contains a gas column 1,450 metres (4,760 ft) deep with a 200 metres (660 ft) deep oil rim below it. It is estimated to contain 1.2 trillion cubic metres of gas and one billion tonnes of liquid condensate and crude oil. Discovered in 1979, it began production under Karachaganakgazprom, a subsidiary of Gazprom. In 1992, AGIP and British Gas were awarded sole negotiating rights, forming a partnership company. In 1997, Texaco and Lukoil signed a 40-year production sharing agreement with the original two companies and the Kazakhstan government to develop the field for world markets. The agreement was turned under a partnership company known as Karachaganak Petroleum Operating (KPO) where Royal Dutch Shell and ENI are joint operators with a 29.25% stake each in the company, and with Chevron and Lukoil owning 18% and 13.5% respectively. In September 2009 the KPO filed an arbitration case against Kazakhstan. The Republic of Kazakhstan appointed Maksat Idenov to lead the negotiations, after which the arbitration was suspended towards an amicable settlement of the dispute and KazMunayGas engaged in entrance into the project in 2010. Under the terms of an agreement reached on December 14, 2011, the Republic of Kazakhstan has acquired through KazMunayGas a 10% stake for $2 billion cash and $1 billion non-cash consideration.
