May 17, 2012. West Siberia-focused RusPetro said that it is confident that it will deliver on its target of 24 wells to be drilled by the end of this year, and will achieve its 2012 year-end production target of 10,400 barrels of oil per day – compared to a year-to-date average production of 4,000 bpd. The reason for RusPetro's confidence, it said, was that because it is now drilling wells at a significantly faster pace than during the first quarter of the year and already has four rigs in operation on its license areas in the Khanty-Mansiysk region of the West Siberian basin. Key highlights from RusPetro's update included a 10-percent increase in proved oil reserves from 157 million to 173 million barrels and a 7.5-percent increase in proved and probable reserves from 1,437 million barrels to 1,545 million barrels.
