2-D SEISMIC DATA INTERPRETATION AND PETROPHYSICAL ANALYSIS OF MEHAR AREA, CENTRAL INDUS BASIN, PAKISTAN

Abstract

The presented study comprises of subsurface structural interpretation of Mehar area using seismic sections and identification of hydrocarbon bearing zones using Petro physical analysis. Mehar block is located in mountainous terrain approximately 190 km west of Sukkur and 300 km north of Karachi, Sindh province, Pakistan. Four seismic lines, and one well named Mehar-01 were acquired from Director General Petroleum Concessions DGPC. Three horizons have been identified on the seismic section using formation tops from well and their depths have confirmed. The marked horizons are recognized using formation tops from well Mehar-01. Seismic lines interpretation identified presence of thrusted anticlinal structure in the area, which is most likely to be trap of hydrocarbon. The zones interpreted by the study includes Ranikot, which suggests that it has 72.13% hydrocarbon Saturation and is 27.86% water saturated.
