Results of 2015: Production using high-tech wells (horizontal wells, including multi-stage hydraulic fracturing) exceeded 11 million TOE. The first stage of the study of the Bazhenov formation at the South Priobskoye field was completed and confirmed the existence of mobile oil reserves. After hydraulic fracturing operations were performed at all the wells, a flow of hydrocarbons was obtained with varying intensity. In addition to Gazpromneft-STC, the other participants in the programme are the Engineering Centre of the Moscow Institute of Physics and Technology (State University), Lomonosov Moscow State University, Gubkin Russian State University of Oil and Gas, and Skolkovo Institute of Science and Technology.
At the Priobskoye field, LLC Gazpromneft-Khantos has introduced innovative non-spherical hydraulic fracturing technology that eliminates restrictions on the number of stages in a single bore. This technology will enable the Company to develop additional hard-to-recover reserves.
The drilling of the first horizontal well has been completed at the Novy Port oil and gas condensate field with horizontal shafts of 1,000 metres. This marks the first time a dual well has been drilled in Arctic conditions. The drilling of extra-long dual wells intensifies hydrocarbon production while simultaneously reducing infrastructure costs.
