2-D Seismic Interpretation and Well Logs Interpretation of Badin Area Lower Indus Basin, Pakistan

Abstract

Two-dimensional seismic interpretation has been carried out in lower Indus basin, Badin area to confirm the reservoir characteristics of lower Goru formation to delineate promising locations for test drilling. Time and depth contour maps of lower Goru confirm the presence of horst and graben structure with tilted normal fault in the given area. On the basis of 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. The average range of volume of shale range 15 to 20%. No major zones can be selected for production due to the high values of water saturation. Cross plots has been generated to confirm the lithologies of the reservoir. Different attributes has been studied to analyses the expected hydrocarbon zone and also to investigate the seismic properly. Coloured inversion shows low acoustic impedence at reservoir level.
