Geodynamics and Petroleum Geology of the Western Bay of Bengal

This report will enhance your understanding of the hydrocarbon prospectivity of the marginal basins of Bangladesh, eastern India and Sri Lanka.

Getech’s unique global gravity and magnetic data and our Structure and Tectonics of Southern Asia Regional Report form the basis for the mapping of eight critical palaeogeographic maps. These, when combined with an analysis of Present Day drainage, enable a review of the landscape evolution and likely effects on sediment dispersal.

The report also contains a review of the geochemical literature, new geochemical modelling, a synthesis of the stratigraphic framework and a basin-by-basin petroleum systems review; all of these features have been used to generate new insights into the petroleum systems of the western Bay of Bengal.
