Print version
04.03.2010
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:
- produce concurrently from a number of targets with different reservoir parameters and reservoir fluid properties;
- improve profitability of individual wells through the involvement of other development targets or different layers of the same target with varying productivity;
- reduce the amount of drilling through the use of one wellbore and the arrangement of simultaneous (concurrent) production of crude oil from different layers with application of one well spacing pattern;
Manufacturing of the equipment has been arranged at the sites of the service companies OOO TMS-group Management Company and OOO Systema-Service Management Company
* The Company produced 25.85 million tons of crude oil from its fields in 2009. About 45% of the volume produced is accounted for application of various methods oil recovery enhancement. The crude oil production consolidated index of TATNEFT Group for 2009 (including crude oil production by the companies with the participation of OAO TATNEFT) amounted to more than 26.1 million tons.
