- Abstract
The oil and gas production rate normally declines due to several parameters, so the artificial lift technique is effective and requires energy to lift the fluid column in the wellbore and optimize production. There are various techniques used recently but the two techniques applicable in the oil and gas industry are gas lift and electrical submersible pumping. Gas lift technique aims to lower flowing bottomhole pressure and decrease the density of the well fluid in the tubing by injecting high-pressure gas from the annulus. Thus, producing a pressure differential that allows flowing the fluid from the wellbore to the surface. On the other hand, ESP lifts the fluid in the wellbore by exposing it to centrifugal force and rotation in each pump stage that changes kinetic energy to potential energy. The design for ESP and gas lift were performed using Prosper software to enhance the production. Prosper is an artificial lift software simulator that troubleshoots, designs and evaluates lifting mechanisms for field optimization and digital oil field system. The analysis of ESP and Gas lift were conducted to choose a suitable method for the determined field. Typical gas injection rates are computed to ensure extreme oil production and sensitivity analysis of water cuts is directed which yields the greatest water cut for upgrading the total oil production. Field data were obtained from existing two wells horizontal and vertical that stopped due to reduction in reservoir pressure, thus required to apply artificial lift methods to lift wellbore fluids to surface and production facilities. The analyzed results showed that, after comparing the maximum oil production rate for both horizontal and vertical wells, the ESP system provided an increase in oil production compared to the gas lift method in this field. Both wells are increasing significantly in terms of production when using ESP systems. Both wells have a total liquid rate, which lies well within the production range of the pump between the minimum and the best efficiency line curve.
