Abstract:
The study area Khipro is situated in the Sanghar District, Lower Indus Basin, Pakistan. This Thesis contains the study and interpretation of 2D seismic reflection data of selected seismic lines of Khipro area. The main objective of this research was delineation of subsurface structures favorable for hydrocarbon accumulation. The seismic data for this dissertation was provided by the Land Mark Resources (LMKR) by the permission of Directorate General of Petroleum Concessions (DGPC). The data comprised of eight seismic lines, base map and well tops of well Naimat Basal 01 and Siraj South 01. Khipro area possesses a good Hydrocarbon potential and several wells are producing oil in the area. Normal Faults prevail in the area with Horst and Graben structures. Horst structures are providing trap for Hydrocarbons. The thickness of Upper Goru Formation is decreasing towards North. The thickness of Paleocene to recent formations is more towards North. Time and depth contour maps of Top Lower Goru, Basal Sands and Chiltan show that there are two compartments. The South Southwestern compartment is showing shallow values and the North Northeastern compartment is showing higher values. The logs at Sands below Talhar Shale show that it is porous and presence of hydrocarbons is also indicated. Thickness of Top Lower Goru and Basal Sands is increasing towards South West. Porosity and Net to Gross ratio is increasing towards North.3D modelling of the area is showing the trend of the Jurassic and Cretaceous rocks.3D modelling also shows that both the wells, Naimat Basal 01 and Siraj South 01 are drilled on horst structures.
