Regional geological studies over parts of Deccan Syneclise using remote sensing and geophysical data for understanding hydrocarbon prospects

摘要

An integrated study using remote sensing and multi-geophysical data was carried out over parts of Deccan Syneclise, for eliminating the inherent ambiguities associated with each of the individual methods, and to understand the hydrocarbon prospects. The subsurface sections constructed using geophysical data such as gravity, electrical resistivity, deep resistivity sounding, magnetotellurics and seismics along various profiles were interpreted for identification of subsurface faults along with their stratigraphic association. The locations of these faults were projected vertically upwards onto the ground surface and marked as point locations on the map in order to facilitate conjunctive study with satellite data interpretation by superimposing one over the other. Additionally, some more regional faults were interpreted from gravity data and superimposed over the above. A prominent geomor-phic anomaly was also interpreted from satellite data and correlated with geophysical signatures. Based on the integrated study, some of the faults were identified as structural traps for possible hydrocarbon occurrences.
