History

Oil and gas operations in the Chinarevskoye Field began during the Soviet era with the drilling of nine wells. Hydrocarbons were discovered in the Biski and Afoninski reservoirs in 1991.

The discovery of the Tournaisian reservoir was made in 1992. In 1997, Zhaikmunai was granted the exploration and production licence and the PSA and commenced exploration activities in the Chinarevskoye Field. Three of the wells that were drilled during Soviet times were reactivated between 2000 and 2002. In 2003, Zhaikmunai discovered the Givetian (Mullinski) accumulation and in 2004 the Lower Permian reservoir was successfully tested.

An oil processing facility was built in 2006. In 2007 gas condensate was discovered in the Givetian (Adatovski) and Southern Tournaisian reservoirs and during the same year, crude oil was discovered in the Bashkirian formation.
