OREANDA-NEWS. October 13, 2011. Gazprom Neft has significantly increased the reserves of its fields in Eastern Siberia. The State Reserve Commission (SRC) approved the decision to increase recoverable reserves in the Chonskaya group of fields (Vakunaysky, Tympuchikansky and Ignyalinsky), which are adjacent to each other and situated on the border between the Irkutsk Region and the Republic of Sakha (Yakutia).

The Chonskaya group's recoverable C1 and C2 oil reserves have grown by over 100 million tonnes, while its gas reserves have risen by more than 175 billion cubic meters. Following the increase, the Chonskaya group's recoverable C1 and C2 reserves will be around 125 million tonnes of oil and 225 billion cubic meters of gas.

Gazprom Neft will continue studying the Chonskaya group of fields with a purpose to develop existing reserves and to discover new ones.

"Further exploration of the Chonsky project areas will enable Gazprom Neft to expand the oil reserves of these fields significantly and to take the necessary investment decisions in order to develop these areas successfully," commented Vadim Yakovlev, First Deputy CEO of Gazprom Neft.
