ESP Design Optimization and Sensitivity Analysis for Oil Well (E-05) using Prosper software

الملخص

The natural reservoir pressure is often sufficient to lift the fluids to the surface. However, when excessive water and gas production occurs, the reservoir pressure may no longer be sufficient. In such cases, an artificial lift method is required to lift the fluids to the surface. The objective of this study is to improve the efficiency of the ESP system and to identify the critical parameters that affect the system's performance of oil well E.05 using Prosper software. Results were obtained and analyzed to determine the optimal design for the well. In this paper, we discussed the ESP model and its impact on productivity. The ESP model is designed to optimize parameters such as reservoir pressure, pump sitting depth, operation frequency, and number of stages. Specifically, the model recommends a reservoir pressure of 3100 psi, a pump sitting depth of 5000 ft, an operation frequency of 60 HZ, and number of stages of 225 stages. By implementing these parameters, the ESP model has been shown to significantly improve productivity.  This model boasts best pump and motor efficiency, making it a reliable choice for optimizing production. The oil flow rate for the well has increased from 916 STB / D to 1008 STB / D, indicating a successful current design for the well. Further research is needed to better understand the factors that affect ESP performance, such as wellbore conditions, fluid properties, and pump design.
