| Abstract | A magnetic survey of the Mt. Rajabasa geothermal system has been conducted and the data were analyzed to determine the reservoir permeability of the study area. Interpretation of magnetic anomalies for the Mt. Rajabasa geothermal system was carried out using the IGRF. Three dimensional modeling was used to interpret the pseudogravity anomaly. The study shows that the demagnetized rock has good correlation with reservoir permeability. Hence, this analysis suggests that demagnetized rocks occur mainly associated with high permeability in the geothermal system. |
