Proper selection of artificial lift method and its operation is challenging in current era for petroleum industry. Electric submersible pump (ESP) is known as an effective method for optimization of production that requires simulation approach before installation in well for operation. The optimization process consists of selecting the appropriate operational frequency for the ESP system and selection of compactible pump model, number of stages and tubing size. The simulation approach has been utilized for a well located in lower Indus basin, Pakistan to install electrical submersible pump. Prosper software was used to design well deliverability model to analyze well with electrical submersible pump for optimization of production with various sensitivity analysis. Initially simulation is carried out with natural flow, later it was tested with ESP to increase its production. Sensitivity analysis was also carried out with different parameters such as water cut, pump frequency, well head pressure. The simulation model shows that the well has the lowest reservoir pressure of 1140 psi, with solution gas oil ratio 215 SCF/STB. The production rate enhances with increases in reservoir pressure or decrease of water cut. The simulation study has shown that centrilift T100-4 inch is best selection of ESP for this well, similarly operating frequency of 60 Hz has given the best result as well started to flow with 2174 STB/day. It was recommended to use centrilift T100-4 inch with 60 HZ frequency for optimum production of Oil.
