2D-INTEGRATED SEISMIC INTERPRETATION PETROPHYSICAL ANALYSIS AND FACIES ANALYSIS OF BADIN BLOCK LOWER INDUS BASIN PAKISTAN

Abstract

Badin area is a common example of extensional tectonics represented by Horst and Graben structures. To carry out the structural and stratigraphic interpretation of the Badin area, two seismic lines 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. Based on Petrophysical analysis the average porosity values for the promising zone range from 10 to 15% and average values of water saturation range from 75-80%, which cause the failure of Doti-01 well. Zone of interest is the Lower Goru. Porosity calculations are made to find out the hydrocarbon saturation is calculated. The main constituents of petroleum system are present, proven by a number oil and gas discoveries but there is still a requirement of advance techniques to improve seismic resolution and quality of interpretation
