Production optimization in ABCD wells through backpressure reduction with HPS: a focus on the existing platform

Abstract

The world is currently in a transition stage towards clean energy, however, while this happens, hydrocarbons (crude oil and gas) will contribute approximately 60% of the total demand, with crude oil accounting for 35%. Likewise, the Mexican Energy Secretariat (SENER) states that, at least until 2050, the majority will continue to depend on fossil fuels. Given this situation, innovation in technologies is sought to extract hydrocarbons found in generally mature deposits, when the natural pressure of the deposit is not sufficient to continue producing with its natural energy. Consequently, artificial production systems are a variety of operating principles, specifically designed to increase hydrocarbon production in the well. The most commonly used artificial production systems are: pneumatic pumping, mechanical pumping, hydraulic pumping, electrocentrifugal pumping, progressive cavity pumping, traveling piston, and hybrid systems. The following article presents the case of a backpressure reduction project, which has as its fundamental purpose to provide a decrease in the downwelling pressure of Wells ABCD-36, ABCD-45, ABCD-51 and ABCD-54, by using part of the existing infrastructure on the platform and allowing its potential to be exploited, thereby aiming to reduce the decline in production of these wells.
