2-D SEISMIC INTERPRETATION OF REFLECTION DATA, SYNTHETIC SEISMOGRAM, PETROPHYSICAL ANALYSIS, ATTRIBUTE ANALYSIS OF MIANO AREA, LOWER INDUS BASIN, PAKISTAN

Abstract

Miano gas field is one of the prominent gas-producing fields of the Middle Indus Basin, SW Pakistan. This thesis work includes preparation of synthetic seismogram of Miano-10 well. Analysis of geophysical borehole logs provides one of the best approaches to characterize rocks within boreholes. For the interpretation of the seismic lines, three reflectors 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. Petrophysics is the one of the most reliable tools for the confirmation of the types of the hydrocarbon and for marking of the proper zone of the interest of the presence of the hydrocarbon by combination of the different logs results. In this dissertation the petrophysics is performed on the Miano-10 well and B sand interval is marked, where there is chance of the presence of the hydrocarbon. Seismic attributes are applied that also confirm the reservoir prospecting zone
