Integrative Analysis of the Geothermal Structure in Kepahiang: Insights from Magnetotelluric, Gravity, and Remote Sensing Techniques

This research was conducted to determine the structure and depth of reservoir using remote sensing as an initial survey assess geological alignment direction, employing ALOS PALSAR radar imagery. Subsequently, further surveys were magnetotelluric gravity methods analyze geothermal reservoir. The data processed Phoenix software, where transformed from time domain frequency Fourier transformation, obtain apparent resistivity phase. MT integrated with data, underwent standard correction procedures Complete Bouguer Anomaly (CBA) map. Two-dimensional (2D) inversion NLCG algorithm 2D forward modeling performed. dominant pattern obtained northwest-southeast, orientation 320° NW or 140° SE. Based on results alignment, a profile is produced that perpendicular straightness. indicated likely located beneath caprock at estimated approximately 1800 m, values ranging 32 256 Ohm-m density value 2.6 gr/cc.
