Abstract

Waterflooding is the injection of water into the formation which functions to push oil into production wells so that it will increase oil production. After the waterflooding is done, surveillance is also needed to determine the results of the waterflooding. The success of waterflooding can be analyzed through Hall Plot analysis, from the analysis results can determine performance and problems that occur. In this study, an analysis was carried out on several injection wells including wells W#108 and W#114 and there were also six production wells including W#170, W#145, W#24, W#87, W#91 and W#52 . From the Hall Plot analysis carried out on the injection well, it can be concluded that the W#108 injection well has a positive skin/plugging problem due to poor quality water, while the W#114 well has a negative skin/injecting above parting pressure indication. And from the results of the connectivity analysis, the W#108 injection well is directly connected to the W#170, W#145, and W#24 production wells. Meanwhile, the W#114 injection well is directly connected to the W#87, W#91 and W#52 production wells. Meanwhile, from the analysis of the prospect of future production wells, the results show that the W#170 production well will reach the economic limit in 2099, the W#145 well in 2090, the W#24 well in 2089, the W#87 well in 2084, well W#91 in 2075 and well W#54 will reach the economic limit in 2076.
