A A petroleum well that has lost the capability to produce fluid above the surface due to a decline in reservoir pressure requires artificial lift to maintain its production rate. One common method of artificial lift used in oil fields is the Electric Submersible Pump (ESP), which is especially effective for boosting production in older wells, such as those in North Sumatra, to ensure optimal output. This research focuses on the RDA field, where two wells were evaluated for the implementation of ESP pumps based on technical and well conditions. To sustain the performance of an ESP pump throughout its lifespan, it is crucial to regularly evaluate and plan its usage. By assessing the ESP pump, one can determine whether it is still operating efficiently and within the productive range by comparing the actual flow rate (q_actual) with the theoretical flow rate (q_theoretical). If the pump is found to be underperforming, a pump optimization plan should be implemented to enhance its efficiency and increase the well\\\'s production rate. This final project utilizes secondary data from wells that have been producing with ESP pumps. While previous optimization efforts have been conducted, this study aims to optimize one well using a different approach. The researcher will analyze well data to evaluate wells that are no longer performing optimally, focusing on those with volumetric efficiency values below the standard pump efficiency average.
