investigation and simulation of parameters affecting the performance of esp well pumps

After drilling wells, operation of oil resources is one of the most important operations. as the production increases or the life of a well increases, the bottomhole pressure and production decreases. various methods are used to increase the lead, such as the use of artificial lift and the installation of various pumps. one of these pumps is electric submersible pumps) esp (, the function of this pump is such that by converting the kinetic energy caused by the movement of the shafts to pressure, it causes the transfer of fluid to the surface. correct operation of esp pump requires investigation of conditions (temperature ...) and properties of the fluid produced (density, viscosity ...). in this paper, some important parameters in the better performance of esp pumps are investigated. then, using pipesim 2020 software, the esp pump was simulated and designed, and the parameters that contribute to its improvement and selection were discussed.
