Abstract

Mahanadi offshore basin is one of the passive margin basins off the east coast of India, flanked by producing KG Basin to the SW and prospective Bengal basin to the NE. The study area lies within shallow water part of the basin, south of present day coast line. The Neogene period, in general, is marked by basinward progradation. The Miocene sequence, which un-conformably overlies the Eocene sequence was deposited in shallow marine to deltaic environment. Overlying Neogene, the sequence comprises of clastics belong to a prograding delta system.
