| Abstract | Sendangan-4 was a development well of Tompaso Geothermal Prospect located in Minahasa, North Sulawesi. The well had a big-hole configuration with 13-3/8” production casing. Early production test resulted in mass flow of ± 500 ton/hr production with flowing enthalpy of ± 950 kJ/kg. After production test, reservoir temperature dropped from 260°C to 70°C causing well failed to discharge. Downhole well survey indicated that casing break occurred. This study analyzed well data including the possibility of well remedial and prediction of well performance after remedial based on wellbore simulation model. |
