Tatneft Increases Production of Hard-to-Recover Reserves with "Intelligent Fields"

Use of automation in the development of hard-to-recover reserves offers the oil companies the ability to optimize equipment performance and productivity of the wells at the account of analyzing their data and to predict periods of the wells' exhaustion based on the past data. At the same time the old wells with a rich production history can be used to predict the behavior of new wells. Modern automation systems allow implementing centralized management of a large numbers of wells with application of remote monitoring.
The decision to implement an "Intelligent Field" pilot project was made at the Management Board Meeting of OAO TATNEFT in June 2009. The main task of the project was to perform pilot operations to intensify production of hard-to-recover reserves on the basis of hydrodynamic control with application of automation aids.
Automation of the oilfield facilities, collection of data and creation of a common database of historical information is performed by OOO Tatintek.
Berezovskaya area of NGDU Almetyevneft has been selected as a pilot test site. As of today, a 3-D geological and hydrodynamic model has been built on the third block and the processes of the field development have been fully automated.
In addition to this more than 250 geological and hydrodynamic models have been created, including such major fields of OAO TATNEFT, as Romashkinskoye, Novo-Elhovskoe, Bavlinskoe, etc. The created geological and hydrodynamic models allow us to observe the 60-year history of their development. The number of the wells covered by simulation is more than 23,000. The created models are maintained in current status and are updated on a continuous basis taking into consideration well drilling, production data and results of geological exploration.
