Company History

The creation of Irkutsk Oil Company was preceded by many years of research and exploration of Eastern Siberia’s oil and gas resources. Eastern Siberia is a relatively new petroleum province. Furthermore, it is considered to have been officially discovered on March 18th, 1962, when the first oil gusher erupted in the village of Verkhnemarkovo in Ust’-Kut district (Irkutsk region). This gave rise to more extensive studies of the region’s hydrocarbon reserves, thanks to which the largest petroleum fields of Eastern Siberia, such as the Yaraktinsky and Danilovsky sites , were discovered.

In 2000, Mikhail Buynov, his son (the current acting President and beneficial owner), Nikolay Buynov, and a few other partners, mostly prominent geologists and specialists formerly employed by the state geological company “VostSibNeftegazGeologiya”, formed Irkutsk Oil Company. That geological company was responsible for the most discoveries in Eastern Siberia, but had fallen apart with the collapse of the Soviet Union. Irkutsk Oil Company acquired shares of two oil-producing units - JSC “Ust’KutNeftegaz” (2001-2007) and LLC “Danilovo” (2001-2004) from various investors on the open market and paid out their outstanding debts.

In 2001, Irkutsk Oil produced its first 30 thousand tons of crude oil and condensate. INK pioneered oil production in Irkutsk region and was the largest local oil producer from 2000 to 2009. This was a difficult period for country’s economy, but the company remained successful due its high performance, efficient management, and innovative approach to looming problems.
