The JTB-89 well has been produced with an artificial lift method, which is the Electrical Submersible Pump, and type DN1100 / 47 Hz / 130 stages has been installed with fluid rate of 716 bfpd, oil production rate of 168 bopd, and 76% water cut with pump setting depth (PSD) of 4910.1 ft [8]. Based on Inflow Performance Relationship (IPR), this well needs to be optimized. If re-design is done, production capability can reach±70% of the maximum production rate. Therefore, it is necessary to increase production rates by evaluating pump setting depth (PSD), frequency, head/stages, and the number of stages on the installed ESP. After evaluating the installed pump, this well does not require to alter the pump type because of pump capacity is still in range. By changing the design of head/stages to 30 ft, increasing frequency to 65 Hz, an increasing number of stages to 160 stages, and increasing PSD to 6750 ft, this design can increase fluid rate production to 1006.85 bfpd
