<![CDATA[This This research was conducted by performing quantitative analysis on data from PT. Pertamina EP Cepu Regional 4 Zone 11 the data included reservoir data, well data, and production data. The objectives of this research are to determine the maximum flow rate and optimum flow rate using the Composite IPR Method in Well KGH 32, evaluate the Volumetric Efficiency of the ESP pump based on the conducted assessment in Well KGH 32, and ascertain the profitability results from the Economic Evaluation in Well KGH 32.The first step in this research was to calculate the Inflow Performance Relationship (IPR) Composite to evaluate the reservoir well's performance. This method was used to predict production rates at specific bottomhole pressures and determine desired production rate targets. Subsequently, ESP Evaluation calculations were performed to determine the effective and efficient pump design considering various aspects, including economic value. The calculation results of the IPR Composite show the IPR Composite curve of Well KGH 32, used to assess well productivity and evaluate ESP pumps. The Q value is 4942 bfpd with a Pwf of 1714.717 bfpd. The optimum Q value is 9730.09 bfpd, derived from 80% of the Qomax value. The optimized Q value is 13,500 bfpd with a Pwf of 779.710, representing 69% of the total Q value. Qomax is 12,162.60871 bfpd with a Pwf of 951.645 bfpd. The Qt max value is 19,564.95 bfpd. Additionally, volumetric efficiency calculations for the installed pump indicate 71% efficiency for pump P-31, indicating suboptimal performance requiring optimization. Economic evaluation of the ESP considers factors such as revenue, electricity costs, water injection, chemical usage, routine expenses, and facility sharing agreements. Daily profit is calculated at Rp. 157,518,753. From this research, it is concluded that the ESP pump at Well KGH 32 needs optimization to enhance efficiency and economic feasibility, potentially achieving greater daily profits. Overall evaluations not only aid in improving operational performance and efficiency but also enable better decision-making based on a deeper understanding of well conditions and potential repair needs. Future steps may involve installing a rotary gas separator to manage excessive gas and adjusting pump designs to enhance overall performance. performance.]]>
