2D-Integrated Seismic And Well Log Interpretation, Seismic Attributes And Rock Physics Of Khipro Area, Lower Indus Basin, PAKISTAN

Abstract

Khipro area is prominent in the Lower Indus Basin for its hydrocarbon (oil and gas) structural traps.. The data used for this study consists of six seismic lines along with their navigation, velocity data and well logs data of one well. Three horizons; Lower Shale , Middle Sand and Sand Below Talhar Shale have been interpreted along with normal faults. Time and Depth contour maps of the three horizons have been generated and the resulting interpretation indicates Horst and Graben structures. The interpretation is further confirmed through seismic attributes analysis. Seismic attributes analysis of seismic section helps in identifying the different lithological boundaries and also confirmed the structural disturbance. Petrophysics is the one of the most reliable tools for the confirmation of the types of the hydrocarbon and for marking the proper zone of the interest for the presence of the hydrocarbon by combination of the different logs results. Petrophysics is performed on the Naimat Basal-01 and 3 zones of interest are identified where there is chance of the presence of the hydrocarbon. Both quantitative and qualitative interpretation is calculated in interest zones. Zone 1 and Zone 3 shows good hydrocarbon saturation, high effective porosity , and low volume of Shale while zone 3 would be effective reservoir. Further hydrocarbon zones are confirmed through rock physics and it also confirmed the lithology
