Within the last three years large efforts have been undertaken to explore the oil potential in Bangladesh. Prospecting for oil in an already well known gas province appears to be a challenge which is presently met by intensive seismic surveys, stratigraphical and geochemkal investigations and exploration drilling.
Seismostratigraphic correlations nearly all-over Bangladesh appear to change some concepts held so far on the stratigraphic age of different sedimentary sequences. The results from seismic stratigraphy are partly in contradiction to the conventional stratigraphic framework and recent palynoiogical results. Nevertheless they are presented in this paper as a further approach to discuss still open questions on the hydrocarbon inventory of the Bengal Basin. The results of setsmo-stratigraphy shed a different light on different structural parts of Bangladesh regarding their oil potential.
