Petroleum source rock properties of the Neogene Bhuban shales,Bengal Basin, Bangladesh

The present study evaluates the petroleum source rock generation potential of the Neogene Bhuban shales from Bangladesh. Organic geochemical and organic petrological methods were used for analyzing 11 drill core samples from 4 gas fields in the basin. Source rock potential, maceral composition, orga...
