Evaluation Study of Electric Submersible Pump (ESP) IND-1000 Pump Model with Analysis of the Flow Rate of Crude Oil in Production Well

Abstract

ESP is an artificial lift with the principle of a centrifugal pump, where the production fluid that enters through the intake will be thrown by the impeller into the diffuser which will then be directed to the impeller above it so that this process repeats until the production fluid reaches the surface. The longer the production well is produced, the smaller or weakened the Pwf pressure will be, therefore an evaluation is needed in order to produce optimal production. The data needed include: well production rate (Qo), well flow pressure (Pwf), Pump Intake Pressure (PIP), Total Dynamic Head (TDH), Pump type, namely IND-1000 pump, Number of stages, Type of motor, HP motor, motor voltage, Electric current, OD motor, Total voltage, and Total starting voltage. The evaluation methodology used is to determine the optimum production rate through IPR calculations using the vogel method, Pump Intake Pressure (PIP), Total Dynamic Head (TDH), number of stages, and horse power (HHP). From the results of this evaluation, the optimal production rate (Qopt) value was obtained, which was 988.552 BPD. This optimal production rate value is still included in the capacity range, which is between 600-1260 BFPD. Because the optimal production rate is still within the range capacity, this production well does not require a new pump replacement.
