Advances in Dual Completion Technology in OAO TATNEFT

Authors: K.M. Garifov, A.Kh. Kadyrov (TatNIPIneft, RF, Bugulma), N.G. Ibragimov, V.G. Fadeev, R.G. Zabbarov (Tatneft OAO, RF, Almetyevsk)

Key words: dual completion system for production from three layers, dual completion system for operation of slim wells, differential pump, separating piston, mineral extraction tax, pressure, production rate, water cut.

The article presents the newly designed dual completion systems of Tatneft OAO enabling the expansion of dual completion technology applications. These include a dual completion system used to produce from three target zones, a dual completion system with a separating piston and commingled production, a dual completion system for production of viscous fluids and a dual completion system for operation of slim wells.
