Production from an offshore oil field – named as X – would be under natural depletion mechanism according to development plan of 25 years from 4 horizontal wells. Natural production plateau time of X oil field will be6 years, so in order to preserve production plateau of the filed longer, it should be added some source ofenergy to the wells to compensate pressure drop within the wellbores. One of the practical methods is usingartificial lift and for this purpose Electrical Submersible Pump (ESP) is designed for each of 4 horizontal wellin this reservoir. In this paper all pump features and its designing parameters will be presented. Toaccomplish the sensitivity analysis on design variables, it needs to make the Inflow Performance Relationship(IPR) model, and outflow model is combined with the inflow model to get a solution point on the rate and bottom–hole pressure of the wells. Finally different values of design variables are applied to the model to investigate the possible variations of the production also its impact on reservoir recovery factor. As a result reservoir recovery factor increases to 8.91 and 11.66 percentages in scenarios of production with different type of ESPs in wells, in front of 6.6% recovery in natural depletion.<\div>
