Remote Sensing and GIS Tool to Detect Hydrocarbon Prospect in Nagapattinam Sub Basin, India

Abstract

Cauvery Basin is one of the pericratonic rift basins located in the east coast of Tamilnadu. The rifting has resulted in a series of horsts and grabens. The present study uses a new technique which was devised with the help of GIS by analyzing the surface lineaments and subsurface linearities effectively. In this present study, a satellite image based analysis was conducted for extracting surface lineaments, and for the subsurface linearities, the basement linearities were extracted from seismic, magnetic, and gravity data. An orientation analysis of these surface and subsurface linear features was performed to detect the basic structural grains of the study area. The correlation between these structural grains and subsurface oil and gas traps was performed to understand the connectivity to the reservoirs. This article discusses in detail about the same and the importance of using surface and subsurface lineament analyses for delineating hydrocarbon reservoirs in the Nagapattinam Sub-Basin of Cauvery Basin.
