Seismic Characterization to Identify Geological Structures and Petroleum Play in Lower Indus Basin, Pakistan

The Cretaceous shale intervals of Talhar and Sembar Formations – distributed in the Lower Indus Basin Pakistan are organic-rich shales that can act as gas plays. Two-dimensional seismic using synthetic modeling has been carried out Khewari oil field to identify petroleum This work was completed with help eight processed migrated lines. Based on structural interpretation different geological structures were marked. character, continuity, coherency reflection patterns indicate area is under an extensional regime normal faults pattern associated horst graben structure. structure favorable for accumulation hydrocarbon. formations overlying Chilton limestone, which a proven reservoir. isopach maps show Shales Formation dipping towards northeast. Precisely characterize reflector, seismogram employed tie well tops profiles.
