INTEGRATED SEISMIC INTERPRETATION:Rock Physics, Engineering, 1-D & 2-D Modelling, Well & Seismic Log Analysis Of Bitrism Area, Lower Indus Basin, Pakistan

Abstract

Bitrisim area is a common example of extensional tectonics represented by Horst & Graben structures. To carry out the structural and stratigraphic interpretation of the Bitrisim area, three seismic dip lines and are interpreted. Two-way time and depth mapping helped in delineated the structural trend and understanding the tectonics of the area. Subsurface mapping reveals that major fault trend is NE-SW. There are indications of reactivation of faults indicating the occurrence of various tectonic periods. Existing structural trend of the area provides basic components of a profile petroleum system. 1-D modeling is done for the well Fateh-01 and. Zone of interest is the Lower Goru. Porosity calculations are made to find out the hydrocarbon saturation. The rock physics analysis is done, based on which we interpret the reservoir rock characteristics. Moreover, water saturation is also calculated.
