Comparative Evaluation between the Pump of Electrical Submersible (ESP) and the Lift of Gas (GL) for Production Optimization

Abstract: The development of hydrocarbon from underground reservoirs to surface production and storage facilities through the wellbore is one of the most important aspects of the exploration and production industry. When a well is drilled, the reservoir fluid flows naturally with the reservoir's primary energy, but when this is not possible, an artificial lift system is built to assist the flow by lowering the hydrostatic pressure within the output tubing. This research compares gas lift (GL) and electrical submersible pump (ESP) for MAJNON 1, well production optimization to determine the best choice for the field. PROSPER software was used to create a natural flowing event, as well as GL and ESP simulations. The results revealed that the ESP system produces 4645.9 STB/day more than the natural flowing case, while the GL produces 785.7 STB/day more than the natural flowing case. ESP also has a higher output rate than GL (3860.2 STB/day, 85.54%). When it comes to the economy, ESP had the highest overall profit (77.46%), with a difference of 22.54% and 26.93% between the GL and natural flowing cases, respectively. However, due to other factors such as water cuts and the replacement of failed pumps, the GL system was chosen for proper field output optimization. Compared to the ESP, which had the highest output capacity, the gas lift was chosen for the MAJNON1 well due to the readily compressed gas availability, higher life expectancy, and lower operating cost
