The Kovyktinskoye gas and condensate field has the largest gas reserves in Eastern Siberia. It serves as the foundation for the Irkutsk gas production center and, together with the Chayandinskoye field in Yakutia, as a resource base for the Power of Siberia gas pipeline.
Figures and facts
Kovyktinskoye was discovered in 1987 within the Zhigalovsky and Kazachinsko-Lensky Districts of the Irkutsk Region.
The field is unique in terms of C1+C2 reserves: Gazprom’s licensed blocks (Kovyktinsky, Khandinsky, and Chikansky) contain 2.7 trillion cubic meters of gas and 90.6 million tons of gas condensate (recoverable).
Well drilling at Kovyktinskoye field
It is planned to produce 25 billion cubic meters of gas per year from the field.
Kovyktinskoye’s gas is characterized by a complex composition: in addition to methane, it contains propane, butane, and considerable amounts of helium. The valuable components will be extracted from the gas at the Amur GPP.

Gazprom obtained a subsurface use license for the Kovyktinskoye field in 2011. The field is currently in pilot production, with geological exploration underway, the existing development wells being studied for their potential, and the membrane technology for on-site helium extraction undergoing testing.

Kovyktinskoye has a complex geological structure. Gazprom will use cutting-edge and efficient technologies in developing the field.
