2D Seismic Interpretation and Petrophysical Analysis of Sanghar Area, Lower Indus Basin, Pakistan (P-1171) (MFN 5562)

Abstract

The basic objective was to get preliminary understanding of the subsurface structural trend and stratigraphy of the Sanghar area in lower Indus basin, which is located in the south western territory of the Indian plate. The study area is tectonically present in extensional regime, dominated by horst and graben structures. The main objective of the project was to describe precisely the subsurface geometry with the help of different seismic techniques in order to understand the petroleum system of the study area. Grabens are of huge exploratory importance as it acts as a kitchen area of hydrocarbon generation. Our main concern was on the interpretation methodology adopted in order to highlight the horizons and time and depth contour maps were generated along with petrophysical analysis of the concerned area. Average velocities were used to find the depths of the formations for seismic section. Bobi 01 holds all the major elements of the petroleum system verified by a number of oil and gas discoveries. However some seismic reflectors were not distinctive.
