2D Structural Modelling and Hydrocarbon Potentiality of the Sitakund Structure, Chittagong Tripura Fold Belt, Bengal Basin, Bangladesh

Abstract: The Sitakund anticline is located within the Chittagong Tripura Fold Belt of the Bengal basin is considered to be the youngest structural feature of the western flank of the Indo-Burman ranges. An attempt has been made to delineate hydrocarbon trap configuration by integrating both surface and sub-surface observations, determining the nature of deformation, predicting the sealing probabilities and relationship between different petroleum elements. 2D structural modelling along the Sitakund anticline suggests that the structure may have a suitable fault-trap setting for hydrocarbon accumulation. Along the footwall block the Bokabil sandstones (with porosity up to 14%) covered by cap rock of Upper Marine Shale (UMS) juxtaposes against the shale-rich Bhuban Formation of the hanging-wall block provides such fault-trap geometry.
