Geoscientific study to locate hydrocarbon prospective zones in a part of Cauvery Basin using Remote Sensing and GIS techniques

Abstract

IRS-P6 LISS III geocoded FCC data in conjunction with Survey of India toposheets (1:50,000) and field inputs were used for thematic mapping. Geomorphic units identified through visual interpretation of FCC include: fluvio-marine sediments, flood plain, coastal plain, beach ridges, swale and palaeo-channels. In addition, lineaments were also mapped. Based on the geomorphology, geology, DEM, subsurface faults and lineaments hydrocarbon prospective zones in a part of Cauvery Basin has been identified. The demarcated prospective zones were compared with the gravity and magnetic data as well as topographical and structural maps.
