2D SEISMIC REFLECTION DATA INTERPRETATION, INTEGRATED WITH FACIES MODELLING, SEISMIC ATTRIBUTE ANALYSIS & PETROPHYSICAL ANALYSIS OF MIANO AREA, SINDH

Abstract

The present study pertains to integrated seismic, petrophysics of Miano (Central Indus basin) area. This thesis work includes preparation of synthetic seismogram of Miano-07 well. Analysis of geophysical borehole logs provides one of the best approaches to characterize rocks within boreholes. For the interpretation of the seismic lines, two 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 are confirmed by fault polygon of time and depth contour maps made from time and depth grids 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-07 well and zone of interest is marked, where there is chance of the presence of the hydrocarbon. Facies Analysis is carried out and different cross-plots are produced using the existing data. It lead to further support of the interpretation results i.e. the reservoir environment, which seems to be a potential zone for hydrocarbon accumulation.
