During four years of cooperation, Naftagaz specialists drilled more than one million meters at the facilities of Gazpromneft-Khantos in the South Territory of the Priobskoye field being a key asset of Gazpromneft as one of the largest fields of the Company.
During the operations under contract, the drilling engineers of Naftagaz has set a production record and drilled a highly sophisticated horizontal well at the depth of 5,472 meters. The Directional Difficulty Index (DDI) achieved was 6.67. This is among the top figures for similar projects in the Western Siberia. For its implementation, Naftagaz specialists, jointly with the Client engineers, developed a new well design. This process solution provides an opportunity to increase the efficiency of horizontal well drilling with borehole length of 2,000 meters by 5 to 8 %.
With RN-Nyaganneftegaz (a subsidiary of NK Rosneft). Naftagaz operates in the Kamennoye oil and gas field in the west of Khanty-Mansiysk Autonomous Okrug. The Kamennoye field is characterized by an extremely complex reservoir structure and low-permeability formation. This decreases the effectiveness of hydraulic fracturing and drilling of horizontal wells.
