2D Seismic Reflection Data Interpretation of Sanjhoro, Pakistan Integrated with fault seal analysis and prospect evaluation

Abstract

In this dissertation, our major aim is on the structural interpretation of the Sinjhoro area in order to find t he probable zone for hydrocarbon accumulation. This dissertation work also includes the fault seal analysis, Petrophysical analysis and reserves estimation. For interpretation, first we create the project on the software and then load the seismic data for fault modeling. Fault modeling is done according to the geology of the area. Synthetic seismogram is generated on well CHAK 66-01. Based on synthetic, four horizons are marked. To make the fault polygon, faults are correlated on each dip line. Contour maps are made to explain the structures. In this dissertation, I have focused on Lower Goru formation. Massive sands are acting as the reservoir in the study area. These maps show the orientation, position and shape of subsurface geological structures. Fault seal analysis is done to tell either fault is acting as a seal to reservoir or not with the help of the Allan diagram. Allan diagram is the diagram which tells us the movement of the formation along the fau lt. Petrophysical analysis is performed on the well CHAK 63-01. The major purpose for the Petrophysical analysis is to evaluate the reservoir zone of interest. After the application of the cutoff parameters, different Petrophysical results are calculated.
