Chernoozerskoye field was discovered by an exploration well in 2007. In-place oil reserves of the deposit amount to more than 3.5 million tons with recoverable reserve exceeding 1 million tons of oil. In situ oil viscosity provides an opportunity to obtain tax benefits.

In accordance with the trial operation program the production of oil from the well was started in January 2008 with application of a sucker rod unit pumping oil to the oil storage section with subsequent removal by oil tank trucks. The initial production rate of the well with this production mode amounted to 20.2 tons of crude oil per day with the water cut of 10%. The pipeline was constructed in January 2009 and the well started continuous production in the amount of 26.8 tons per day with 7% water cut.
