Abstract

To meet the demand for electricity in the Ungaran area in particular, it is necessary to build geothermal power in the Gedongsongo area, but there are no production facilities, both below and on the surface, so the authors plan production facilities on the surface, regarding the selection of optimum pipe diameters. The goal is to build a power plant with a capacity of 110 MWe based on the optimum diameter, which provides the smallest possible loss of pressure and temperature and the maximum possible mass flow, for this the authors use the pressure loss profiles from Begg and Brill and temperature loss using the 1st law of thermodynamics, With two-dimensional Newton Rapson manipulation, it can be seen that the drop in pressure and temperature at the exit point simultaneously on a pipe segment. In this field, there are 4 clusters, including: cluster 1 (4 wells), cluster 2 (5 wells), cluster 4 (2 wells), each 2 wells served by 1 separator, starting from the pressure of each wellhead 15 Barg, dryness 0.25 and rate 105.5 kg/s, insulation thickness 8 cm, polyurethane type, pipe length from wellhead to separator 150 m, resulting in pipe diameter from 18-24 in, minimum thickness from 30.82-39.62 mm, pressure drop 0.55 Barg, temperature 1.67 oC, from separator to turbine input, pipe 50-1200 m long, yield diameter from 16-48 in, minimum thickness 25.01-61.50 mm, pressure drop 1.61 Barg, temperature 3.11 oC, with a generated power of 154 MWe

Abstract

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.
