Abstract

Injection wells X and injection wells Y are one of the waterflood injection wells which are predicted to experience damage which results in a decrease in production flow rate performance. To find out the performance and problems that occur in these wells need to be analyzed. The initial assumption was that there was a problem with injection well X which was identified by a decrease in the water flow rate from the well due to plugging. One of the methods used for injection well analysis is the injectivity test with the Hall Plot method. Therefore, in this study, Hall Plot analysis will be carried out to evaluate the problems that occur in injection wells X and Y injection wells. Based on the analysis on injection wells X, the results show that the injection radius is 109.113 felt, indicating how far the water has been injected. Slope undamaged and slope damaged respectively 0.29 and 2.38. Transmibility undamaged and transmibility damaged respectively 153.40 and 16.498. The skin factor obtained is selbelsar 52.631 which indicates the presence of formation looseness. And the injectivity index selbelsar 0.62 indicates the result of stimulation. Whereas in the Y injection well, based on the Hall Plot curve that was carried out, a good trendline result was obtained which indicated that there was no damage to the Y injection well.
