OREANDA-NEWS. JSC TATNEFT continues developing advanced technologies for reservoir pressure maintenance (RPM) aimed at reducing energy costs and increasing operations' efficiency. With their help, the Company's professionals ensure protection of injection wells downhole equipment against high pressure and corrosion, as well as provide for all round optimization of the RPM processes.

The injection was started into 99 new injection wells during 6 months of 2015. Implementation of the program to protect production casing strings against high pressure and corrosive destruction was continued with installation of 162 M-1X packers. Overall, 4,740 injection wells of the Company have been equipped with M1-X packers since the beginning of their installation. Totally, more than 65 of the current injection well stock of the Company has been equipped with highly leakproof packers.

The DCI technology (Dual completion and injection) has been implemented in 33 injection wells for the past half a year. Currently, this technology has been applied in 687 wells. Additional production from the introduction of the DCI technology amounted to over 1.6 million tons.

Within the framework of the target-oriented program, anticorrosive performance tubing was run in at 169 wells. To date, the existing protection of the well injection stock operating with effluent and produced water amounts to 89.5%.
