TATNEFT Robotized SVN Wells
Monitoring of extra-viscous oil production at the facilities of TATNEFT switched to robotic control.
The tool for monitoring operational data on wells was implemented by the specialists of the Production Department of EHV, Tatneft – Digital Development and STC Automation, Measurements, Engineering. Algorithms for solving this problem were developed jointly with the technologists of the Tatneft-Production division.
The unique system covers 24 raising the stock of EHV deposits. Due to the science-intensive specifics of EHV production, each well is equipped with a variety of specialized sensors. All production data is sent to a web portal accessible to specialists from any device connected to the Internet. TATNEFT specialists have developed algorithms that allow the analysis of telemetric data without human intervention. In case of any deviations in the production process, the system itself “adjusts” to new conditions, choosing the most optimal operating mode. After eliminating the problem, the optimization and automatic control algorithm returns the well to the previous production parameters.
Evaluation of the effectiveness of management of the development of EHV fields is carried out using calculations of technical and economic indicators both for wells and for the field as a whole. Based on the results of the interpretation of the research by artificial intelligence, a digital proxy model of the field is built, which reflects the oil-saturated thicknesses, contours, contours and other characteristics. The placement of wells in the field is carried out in several versions: the rapid placement proposed by the robot, the actual placement, the robotic express placement. Based on the data obtained, predictive calculations of oil and liquid production, steam injection, taking into account the actually achieved values for the entire period of field development, are constructed.
The project of robotization of functions for monitoring and control of wells operating modes for the production of super-viscous oil allows to reduce oil shortages and increase the duration of the operation of downhole pumping equipment.
The new technology covers the processes from well operation control to the economic assessment of field development and allows to significantly reduce losses during the production of EHV.
