2D Seismic Reflection Data Interpretation of Meyal Area Upper Indus Basin Integrated with Reservoir Characterization by Using Wireline Data along with Post Stack Seismic Inversion

Abstract

The main purpose of the study is to interpret seismic data of the Meyal field by evaluating ydrocarbon potential of two wells MEYAL-Ol and MEYAL-17, Punjab, Upper Indus Basin, Geographically the Meyal field is located in Punjab province having coordinates Latitude 33° 20'0l.1" N and Longitudes 72° 02' 53.2" E. Two-dimensional seismic interpretation has been carried out in upper Indus Basin, Meyal area to confirm the reservoir characteristics of Chorgali and Sakessar Formation to delineate promising locations for test drilling. Time and Depth contour maps of Chorgali and Sakessar help us to confirm the presence of anticlinal structure in the given area. Surface contour maps of both Formations give the real shape of sub-surface structure, which is anticlinal. This anticlinal structure acts as a trap in the are~, which is best for hydrocarbon accumulation. Different attributes has been studied to analyses the expected hydrocarbon zone and also to investigate the seismic properly. Seismic attributes applied on line 97-MYL-Ol also confirms the seismic interpretation. On the basis of petrophysical analysis the average porosity values for the promising zone range from 5 to 10% and hydrocarbon saturation ranges from 65-70% contirm that Chorgali and Sakessar formations are the main · reservoirs of the Meyal area. Different crossplots has been generated to confirm the lithologies of the rocks . After it seismic invers ion has been studied to confirm the seismic interpretation.
