The purpose of this study is to activate the use of Electrical Submersible Pump (ESP) pumps installed in the CP-41 Well and to optimize production for increased production rates properly. The method used in this study is the Inflow Performance Relationship (IPR) analysis curve to determine the well’s potential production, evaluation of the ESP pump’s volumetric efficiency, and redesign including setting the installation depth (Pump Setting Depth/PSD), changing the pump type, and modifying the number of pump stages.

The evaluation results show that the ESP pump installed in the CP-41 Well type IND 750/50 Hz, with 343 stages and a PSD of 5578.455 ft has a volumetric efficiency of 75.65% and a pump efficiency of 45%. The actual production rate (Q gross) of 665 bpd is lower than the theoretical production capacity (Q theoretical) of 732.5 bpd. Therefore, optimization was carried out by maintaining the PSD, but changing the pump type to IND-1000/60 Hz and the number of stages to 191. The optimization results showed an increase in the production rate to 958 bpd with a pump efficiency of 58.44%, an increase of 13.44% from the previous pump.

The relevant innovation is to redesign the ESP pump to increase fluid distribution and well production efficiency according to formation productivity. The new technology applied increasing the pump operating frequency from 50 Hz to 60 Hz. The practical application of this study is to provide recommendations for optimizing production in wells using the Electrical Submersible Pump (ESP) method with artificial lift to achieve optimal production.
