Abstract

Identification of geological structures must be done through observation of geological structures through remote sensing imaging to identify geological structures on the surface and interpretation of the results of geophysical surveys to identify continuity of subsurface geological structures. Geological structures or fault is an important parameter in geothermal exploration. It could be able as a secondary permeability that control and improve the fluid flow within a reservoir. Lineament analysis and gravity analysis (FHD & SVD) can be used to identify geological structures on the surface and subsurface. The surface structure analyzed with DEM satellite image and gravity data processing used Surfer 13 Software to separate (Complete Bouguer Anomaly) and filtered (First Horizontal & Second Vertical Derivative) the data. The result of fault correlation between remote sensing analysis had NW-SE dominant trend lineaments, similar pattern with FHD result. Based on SVD curve, the structure in this research area dominated by reverse faults and normal faults. By using geophysical tools (gravity), initial data from remote sensing is getting stronger.
