Increasing the Efficiency of the Orenburg Oil and Gas Condensate Field Development Through the Introduction of an Intelligent Gas Injection Control System to Optimize the Gaslift Operation of Wells

Gaslift is widely used in the world practice of oil production. At the moment, one of the realizations of this production method is used at the Orenburg oil and gas condensate field - a gas compressorless method of operating wells. The paper presents the experience of Gazpromneft-Orenburg on the introduction of an intelligent gas injection control system.

The advantage of the compressor-free gas-lift mode of operation is a significant reduction in operating costs. A feature of this method of operation is the need for continuous control of injection into each well. A system with automatic control valves was introduced to automate the injection of gas in the Orenburg oil and gas condensate field, which allowed point-setting of the injection, constantly monitoring and measuring the gas injection for each well.

The implementation of the concept of an smart field allowed Gazpromneft-Orenburg not only to optimize the operation of the gas lift wells, but also to optimize the work in the field as a whole, including:

1. the release of the time for personnel to analyze and make decisions by reducing the routine operations;
2. optimization of the operators’ work due to remote control of technological objects, wells;
3. Reducing the risks of labor and personnel safety in conditions of high hydrogen sulphide content.
