OREANDA-NEWS. June 01, 2011. TATNEFT applies controllers of Lufkin Automation Company with the aim of succeeding in solving industrial and technological problems in oil production, management of the wells operation and its optimization. The controllers help to remotely control downhole pumping equipment operation and set the wells operating mode, thereby increasing the rate of crude oil production and bringing down the operating costs. As of today, there are 2,507 controllers in the operation at the wells of the Company, reported the press-centre of TATNEFT.

Application of Lufkin Automation controllers allows real-time continuous monitoring and diagnosis of the downhole pumping equipment, monitoring of the system parameters; taking dynagraphs with transfer of information to the control panel for prompt actions either from the field control panel or from the wellhead.

The process settings fixed in the controller, give the opportunity to adjust production parameters and control the load on the balancer head of the sucker rod pumping units, thereby preventing breakage of rods. The controller software allows selecting the desired mode of crude oil production and automating this process.

The applied software and hardware packages allow to automatically maintain a dynamic level of the pump intake, and thereby increase the rate of fluid production and reduce the energy required to lift the liquid, reducing the length of the downhole pumping equipment assembly hanger and the number of rods for a given mode of production.

Application of Lufkin Automation controllers is related not only with the monitoring of the downhole pumps and surface equipment, but also to control the process of oil fields’ development. They help monitoring the production rates and downhole pressure values, as well as their interaction in the operation profile of production and injection wells.

Information Reference
TATNEFT has started introduction of Lufkin Automation controllers since 2005. The greater part of the controllers is implemented at newly commissioned wells, dual completion and production wells and high production rate producers in accordance with investment programs.
