INTEGRATED APPROACH TO HYDROCARBON ASSESSMENT OF MIANO AREA OF LOWER INDUS BASIN PAKISTAN USING 2D SEISMIC AND WELL LOGS DATA

Abstract

Quantitative and qualitative interpretation of Miano Area has been carried out for hydrocarbon assessment through integrated geophysical technique. 2D seismic and well data of Miano-05 is incorporated to pursue the research work. Seismic interpretation provide aids for subsurface structural interpretation and borehole logs are employed for reservoir characterization. For the interpretation of the seismic lines, three reflectors Lower Goru, C-Sand and B-Sand are marked by correlating synthetic seismogram on seismic section. As the area of study lies in the Lower Indus Basin, horst and graben geometry in this region is common which is confirmed by fault polygon of time and depth contour maps made from time and depth grid respectively. Petrophysical analysis of Miano-05 has been carried out by incorporating the cumulative response of all the available logs to mark the potential zones. Combined wireline logs response of Miano-05, pronounced 12 meters hydrocarbon potential zone in the study area. Furthermore, from this study we also get the idea about the sea level at the time of deposition
