Abstract:
Horst & Graben structures are a very common example of extensional tectonics as represented by
Badin area, Southern Sindh Monocline, Pakistan. In order to carry out the structural and
stratigraphic interpretation of the Badin area, eight seismic lines along with four wells are
interpreted. Two way time and depth mapping helped in delineating the structural trend and
understanding the tectonics of the area. Subsurface mapping reveals that major fault trend is NWSE. There are indications of reactivation of faults indicating the occurrence of tilted fault blocks.
Existing structural trend of the area provides basic components of a prolific petroleum system.
1-D forward modeling is done for the Jabo-01 well and zone of interest is the B Sands of Lower
Goru Formation. Porosity calculations are made to find out the hydrocarbon saturation. The main
constituents of petroleum system are present as proven by a number oil and gas discoveries but
there is still a requirement of advance techniques to improve seismic resolution and quality of
interpretation.
