Abstract

A very important Geophysical subject, Potential methods (Gravimetric, Magnetic, etc.) has enormous applications and can play a very decisive role in guiding the exploration activities in a basin. To start with any exploration activity in any basin, one must know the tectonic set-up and the sedimentary thickness in the basin. In general, most of the sedimentary strata in the subsurface follow the trends, which were existing at the basement level. If the basement topography can be mapped faithfully, it will be very good beginning to start with further exploration activities in the basin. with the advent of digital computers, the point to point information of the subsurface can be inferred by quantitative interpretation of gravity-magnetic anomalies. Apart from providing structural and tectonic information, the methods may be used to delineate the zones of porosity (or mass deficiency), zones of likely occurrence of hydrocarbons within the sediments and even in reservoir management also they may be of some help. Although no specific research work in the present paper, a comprehensive account of the efficacy of these techniques is provided and an effort has been made to draw the attention of Geophysical community to use these methods as a part of routine interpretation.
