New field discovered by Rosneft in Siberia

Rosneft geologists discovered a large new oilfield within Mogdinsky and East Sugdinsky license areas in Katangsky District of Irkutsk Region (East Siberia).

 

Rosneft geologists discovered a large new oilfield within Mogdinsky and East Sugdinsky license areas in Katangsky District of Irkutsk Region (East Siberia). Rosneft obtained the licenses for both plots through the auction in 2006. The field was named after Nikolay Savostyanov, who in 1976 – 1990 was in charge of the Principal Division for Oilfield and Site Geophysics (Glavneftegeophysica) of the USSR Ministry of Oil Industry, and in 1993 — 1997 – of Rosneft’ s Department for Geophysical Operations.


The field’ s primary recoverable reserves under С1+С2 categories exceed 160 million tons, being sufficient to take the field as the strategic one. The deposit is in complicated geological setting with a number of other properties that indicate the need for further exploration in order to work out the best development method. The field is located approximately 80 km from Verkhnechonskoye Oil & Condensate Field, where Rosneft takes part in the development, and 150 km from East Siberia – Pacific Ocean trunk pipeline. Exploration in the area started in the 1980-s; however, the first commercial oil was recovered only in 2009 as a result of exploration drilling.


In 2010 the Company intends to continue exploration at the license blocks of Irkutsk Region, particularly to run 2D seismic of 2930 km and resistivity survey of 3700 km. Drilling of four new wells is also scheduled. In general, Rosneft performs exploration in East Siberia (Irkutsk and Krasnoyarsk Regions) in 26 license areas with the attributed available resources of over 2.5 billion tons of oil equivalent. Particularly for 2010 it is planned to run 5325 line km of 2D seismic, 400 sq. km of 3D and to drill 12 exploration wells.
