Abstract

A decrease in the flow of production in general, a decrease in reservoir pressure strength to push oil and gas to the surface. One of the assistive tools used to overcome this problem is to use artificial lifts such as the sucker rod pump (SRP). It would be better than running when the efficiency of the SRP pump can also improve the reduction. What happens to the problems that occur with the SRP pump is to do a dynagraph chart analysis. Well U, V, W and X are wells that use an SRP pump. To see the performance of the SRP installed in the well, a dynagraph analysis was performed. The dynagraph test is usually done once a month or conditionally, there is a decrease in production. This test is carried out by installing a Horse Shoe Tranducer (HST). Dynagraph graphs for wells U, V, W and X were analyzed by reading the movement of the rod pump during production. Dynagraph is the result of rod pump movement by up stroke and down stroke of each SPM (Stroke Per minute). The results of this analysis indicate the problem of performance problems in well X. This problem occurs due to high friction on the pump, which means that the working pump has decreased performance. This is in line with the incidence of decreasing production flow in the well. To solve this problem, a pump redesign was carried out by changing the value of the step length and speed of the installed pump. Based on the research results using the IPR curve of the Wiggins method, changes in the value of pump speed and step length are obtained where at the time of high friction S = 96 inch and N = 14 SPM and after redesign it changes to, S = 186 inch and N = 6 SPM Efficiency. pump also increased initially 41.58% to 85.05%.
