Abstract

Globally deepwater remains relatively unknown frontier, and Andaman sea area is one of those. In island arc tectonic setup like Andaman Basin, high heat flow regime is prevalent in fore arc part and even more so in back arc region due to its proximity to spreading centre. This kind of set up is responsible for enhanced maturation and in turn hydrocarbon generation. Exploration history of adjoining producing basins in Myanmar and North Sumatra basin of Indonesia has indicated the fact. A number of prospects have already been identified with the existing 2D and 3D seismic data set in all the three major tectonic set ups (Fore Arc, Volcanic Arc and Back Arc) of Andaman basin. Prospects / Plays like Carbonate platform, Miocene carbonate buildup, fault aided anticline, Pliocene high amplitude channel fan features and basal Miocene structural inversion are very interesting in the ponded lows between accretionary prism of fore arc system.
