The incorporation of Permanent Magnet Motors (PMM) in Electrical Submersible Pump (ESP) systems as a means to increase efficiency and decrease energy consumption has garnered considerable attention. This study examines the integration of PMMs in ESP systems, notably in the context of two wells, TM-025 and TM-027, each of which presents unique production challenges. TM-025 confronts sand production issues, while TM-027 faces gassy oil well troubles. The primary objectives of this study are to design ESP systems with PMMs, compare their performance to that of Induced Motors (IMs), and evaluate the impact of the number of poles in PMMs using sensitivity analysis. To accomplish these objectives, simulation-based sensitivity tests are conducted to analyze nodal behavior and identify optimal operating points along the pump performance curve. This study includes the selection of ESP pumps, a comparison of the use of PMMs and IMs, and an examination of the effect of the number of poles in PMMs on system performance. The study proposes specific ESP pump configurations for each well based on the conducted analyses. Incorporating a PMM with two poles is advantageous for TM-025, which employs an NHV(790-1000)H pump with 73 stages, a frequency of 60 Hz, and a flow rate of 470 BFPD. For TM- 027, however, an NFV230 pump with 268 stages, a frequency of 50 Hz, and a flow rate of 21 BFPD along with a PMM with two poles is recommended. These results contribute to the comprehension of PMM utilization in ESP systems and offer insights for optimizing production efficiency.
