Shadizadeh, M. Zoveidavianpoor∗ Petroleum University of Technology Petroleum Engineering Department, Abadan, Iran Abstract Production optimization ensures that wells and facilities are operating at their peak performance at all times to maximize production. This paper describes a procedure, to develop Inflow Performance Curves, Tubing Performance Curves and Choke Performance Curves, for one of the Iranian southern oil wells, from the results of a multiphase flow simulator (PIPESIM). The goal of this project is to optimize the production from one of the southern Iranian oi l fields. Increasing the choke size leads to maximizing production, and causes an optimum reduction in wellhead pressure and bottomhole flowing pressure. Controlling flow patterns in all sensitivity analysis play a major role in selecting the proper variables. Using 7in. OD tubing size rather than 9 5/8 in. casing size and selecting 9/16 in. choke size rather than 7/16 in., the wellhead pressure between 700 to 1180 psia will be the result and
