Evaluation of Hydraulic Fracturing Stimulation Based on Engineering and Economic Aspect at “ADN-007” Layer A3

The "ADN-007" is a production well located in the "APS" Field of the South Sumatra Basin, which has been operating since 1959. In 2023, a workover and hydraulic fracturing stimulation were performed at a depth of 1280 meters, precisely in the Talang Akar Formation, which consists of sandstone. The evaluation involved collecting engineering and economic data and performing calculations such as fracture geometry using the PKN 2D (Perkins-Kern-Nordgren) manual method, Fold of Increase using the Cinco-Ley Samaniego Dominique method, production prediction using the IPR Pudjo Sukarno method, and economic analysis. Based on the geometry evaluation calculations, the fracture length (xf) formed is 85.339 m, with a fracture height of 18.9 m, and an average permeability of 56.692 mD. The effective well radius (rw’) is 69.996 ft, and the total skin after hydraulic fracturing stimulation is -3.992. According to the nodal analysis results, “ADN-007” has optimal production after stimulation from 2023 to 2027, producing consecutively 330 b/d, 260 b/d, 198 b/d, 130 b/d, and 79 b/d. However, based on economic aspects, this stimulation is classified as uneconomical because the Profit to Investment Ratio value obtained is only 0.65.
