2D SEISMIC REFLECTION DATA INTERPRETATION INTEGRETED WITH PETROPHYSICAL AND FACIES ANALYSIS OF KHIPRO AREA, LOWER INDUS BASIN, PAKISTAN

Abstract

The present study pertains to the structural and Stratigraphy interpretation, facies analysis, petrophysical analysis and estimation of rock physics of Khipro area.. Khipro area is prominent in the Lower Indus Basin for its hydrocarbon (oil and gas) structural traps.

For interpretation of these seismic lines two reflectors and normal faults were marked.The marked horizons were identified using formation tops from wells and their depths were confirmed through correlation with synthetic seismogram. From time and depth grids time and depth contour maps of the horizons that were generated to understand the spatial geometry of the structures and the nature of geological structures as identified by the seismic section of the area. Normal faulting as identified on seismic sections confirmed that study area lies in extensional tectonic regime. The resulted seismic interpretation of these lines confirmed Horst and Graben structures by normal faulting. A detailed petrophysical analysis was conducted in order to mark the probable zone of interest in the Basal Sand reservoir in the area.
