OREANDA-NEWS. July 28, 2011. A seminar on the subject "Usage of the drilled well stock to create an optimal system of producing the residual reserves" with participation of chief geological engineers of TATNEFT's structural divisions and service companies was held at TATNEFT on the basis of Aznakaevskneft, which is one of the largest Oil and Gas Producing Boards of the Company, was held, reported the press-centre of TATNEFT.

The information on the status of using the drilled wells stock, as well as the detailed analysis of the operational well stock at TATNEFT's oil fields was presented to the seminar's attendees.

Currently, one of the major challenges facing the geologists of the oil and gas producing divisions of the Company is the maximally efficient usage of the drilled well stock. The ways of solving this problem were proposed by the seminar participants. In particular, they discussed topical issues of the influence of the well spacing density on the rates of producing recoverable oil reserves, the return to service of the earlier disconnected layers, the effectiveness of the wells re-liquidation cases, as well as the results of applying the technology of dual completion and production/injection, etc.

The speakers presented their own experiences, offered their technologies of stimulating the producing formation, as well as the equipment used for the development of hard-to-recover reserves.

The participants of the workshop expressed their confidence that the exchange of views and experience will greatly assist in meeting the production goals.

The seminar was also attended by representatives of scientific and industrial enterprises of Tatarstan and Bashkortostan.
