Abstract

For the remote location and unavailability of data, the Andaman deepwaters was never considered for hydrocarbon exploration until very recently. With hardly a few line kilometers of 2D data and no exploratory drilling, initial understanding of the region was rather poor. Exploration activities by the Eni-led consortium in the last few years have, however, revealed the presence of a completely unexplored rift set-up, much inline with the nearby North Sumatra and Mergui rift basins situated on the eastern side of Mergui Ridge. Current studies on regional geological correlation between the East Andaman Basin and analogous North Sumatra and Mergui Basins, coupled with 2D & 3D seismic data interpretation convincingly point out a close resemblance of tectonostratigraphy among them.
