UPGRADE OF A CONVENTIONAL PUMPING UNIT WITH A COMPRESSOR FOR PRESSURE REDUCTION IN THE CASING, AIMED AT INCREASING OIL AND GAS PRODUCTION AND REDUCING CO2 EMISSIONS

Abstract

In the paper, the authors are conducing research into designing and upgrading the conventional system of oil production using a compressor for pressure reduction in the casing, aimed at increasing oil and gas production and reducing CO₂ emissions. As oil exploitation progresses, the natural pressure of a reservoir decreases, which results in reduced production from the wells. Therefore, compressor design becomes essential for production optimisation. The paper analyses the methodology of designing a compressor which is integrated into the existing sucker rod pump systems, bearing in mind specific pumping unit dimensions, the annular pressure and the quantity of produced gas. The proposed approach includes precise flow dynamics measurement and analysis, as well as optimisation of the geometry of compressor installation in order to achieve maximum efficiency. Pilot projects at nine wells have shown a significant increase in fluid production and decrease in CO₂ emissions by using a closed casing and directing gas into the production line. The research provides an insight into possible benefits of integrating a compressor with production systems, thus ensuring a more sustainable approach to oil and gas exploitation.
