OAO Tatneft continues to develop the technology of dual completion and production (DCP) of two or more layers through one borehole. By the beginning of this year appropriate equipment was installed in 564 wells. Incremental oil production from the beginning of the systems operation exceeded 1.1 million tons with the average increase in production rate per well amounting to 3.7 tons per day. In addition, the technology of dual completion and injection (DCI) was implemented at 135 injection wells. In the process of implementation and operation of wells with DCP is continuously being improved in view of the equipment, as well as the technologies applied.
Additional 170 DCP systems have been scheduled for installation in 2010 with introduction of DCI technology at 93 injection wells. The strategic goal is to reach the amount of 1 million tons of oil annual production through application of these technologies.
Application of DCP and DCI technologies allows to:
