  4. Abstract:
  5. Production optimization is defined as the process of maximizing oil production over the long term while minimizing total production costs. The overall goal is to achieve the optimum profitability from the well or field. In this process, the reservoir system can be considered as a multiple input–output system. In this complex system injection and production wells are known as inputs and outputs. The output of the system is often affected by various parameters consisting reservoir conditions, petrophysics, and PVT data. The optimization of the injector rates and number and installation of submersible pumps are the main issues which have been studied in this paper. Determining the factor with the highest influence on production is of great interest and value. The aim of this paper is to develop different scenarios until 2026 in which above factors are considered; therefore, by comparing these scenarios, the best plan can be selected according to these factors as a combination of different separate scenarios along with economical and other related issues. In this paper effect of drilling new wells is also studied. The optimized plan consisted of opening a certain producer after its work-over, performing work-over on two certain producers, installing down-hole pumps in five certain injectors, increasing and reducing the injection rates of two and three certain injectors, respectively, and drilling six new producers. This optimized plan shows a 13.44% increase in recovery factor in comparison with the plan in which there are no injectors in the field. © 2017, The Author(s)
