Abstract

The characteristics of heavy oil are characterized by high viscosity so that it has its own challenges when it comes to production and requires special techniques to produce it. As is the case with field Y where the hydrocarbon fluid has a high viscosity, to flow and produce it the application of the cyclic steam stimulation (CSS) method is applied to reduce the viscosity of the oil. Then the next challenge is where the reservoir pressure is not able to push the oil naturally to the surface, so it is necessary to install an artificial lift at the beginning of production. It is known that well X uses a type of artificial lift in the form of a sucker rod pump (SRP), but during production there are grains of sand that come along with the fluid. reservoirs. As a result, the performance of the SRP pump is not optimal and is damaged. Therefore, to overcome these problems, a compatible artificial lift is needed. Based on the type and character of the pump that is suitable for application to field Y well X, a progressive cavity pump (PCP) pump can operate properly if the well experiences sand problems and high oil viscosity. To overcome the problem of sandiness, the well is equipped with a screen liner. After analysis, well X still has the potential for development where it is known that the WC is 83% and the maximum flow rate is 250 BFPD. The existing pump (SRP) could not operate due to sand problems. As an alternative, an artificial lift conversion of SRP to PCP was carried out based on a desired flow rate of 200 BFPD, so the Weatherford EDM 200-4100 pump model with a diameter of 3.54 Inch and a PSD of 228 ft was selected. If the pump is applied at 100 RPM, a flow rate of 206 BFPD is obtained. Based on the results of reservoir pressure sensitivity, if there is a decrease in reservoir pressure, well production will decrease and if the pump speed is increased to 200 RPM, the maximum pump flow rate is 210 BFPD.
