• Processed gravity data using mathematical calculations in Microsoft Excel to generate Complete Bouguer Anomaly rn(CBA) values with high precision and accuracy, conducted Bouguer anomaly separation to distinguish shallow and rndeep anomalies, performed spectral analysis, and applied First Horizontal Derivative (FHD) and Second Vertical rnDerivative (SVD) analyses to evaluate gradient variations in gravity anomaly maps using Oasis Montaj.
• Determined the Region of Interest (ROI) within the study area by considering geological conditions, developed initial rnmodels, and conducted 3D inversion modeling using the Occam inversion method to generate a detailed rnrepresentation of subsurface structures.
• Applied Euler Deconvolution method within 3D modeling to identify subsurface structural features controlling the rngeothermal system in the study area. Evaluated structural trends and depth estimations to improve the rncharacterization of subsurface conditions and support geothermal exploration interpretation.
