The Surma Basin in the Northeast of Bangladesh is a proven Miocene Gasprovince and was structurally stamped by the contemporaneous interference of two major tectonic movements, ie. the emerging Shillong Massif in the North and the West-progroding mobile Indo-Burman Fold Belt. Basin relief, structural elements, growth and style as well as geochemical data with respect to hydrocarbons, source rocks and maturity are discussed. Related to the clear cut pre- and post-early Pliocene situation, change of migration pattern and coincidence between hydrocarbon generation, migration, accumulation and trap growth are analysed. Finally, the further prospectivity of the Surma Basin is commented upon.
