Abstract
With the start of oil production from wells, the pressure will drop over time. If this pressure reduction is not controlled, it will reach below the bubble point and after some time it will cause problems in optimal production. Solving production problems includes two categories: well-oriented and reservoir-oriented. In the well-centered method, installing gas injection valves or a pump inside the well, will increase the production for a longer period of time. In this study, of one of southwestern fields well of the country was investigated and the optimal conditions were simulated with the help of Prosper software. For simulation, the reservoir fluid conditions and the characteristics of the well are necessary. In this study, the information of the reservoir fluid has been collected through laboratory tests. According to the results of continuous gas injection simulation, this extraction method can increase the current rate of oil production from 695 barrels per day to the desired rate of 1200 barrels per day. The main mechanisms that lead to an increase in oil production include the expansion of gas along the well column and the weight reduction of the oil column and the transfer of oil by gas to the surface.
