Abstract:
The Southern Indus Basin of Pakistan is rift and passive margin basin, situated on the western side of Indian plate. The area was fed by the sediment from Aravalli-Delhi mobile belts. The Southern Indus Basin is pocked by surficial expression whose existence is varied in space and time. The passive nature, of western margin, ensured that many custatic sea cycle with different ranges have to be preserved in time. The 2D seismic interpretation corroborates the literature claims of rifting and shear-induced strike-slip faults of Indian Plate which led to development of compartmentalization of structures. The petrophysical analysis inferred the genetically linking of reservoirs zones (Basal and Massive Sand) where in Massive sand are more productive in term of hydrocarbon production. The wireline log sequence stratigraphy is performed on the 3 order of cyclicity and overprinted on the global eustatic sea level events. The sequence stratigraphic framework used to define the fourteen sequences with major hiatal strata. The seismic stratigraphic analysis justified the stratigraphical claim regarding the Lower Goru Formation deposition.
