2D SEISMIC REFLECTION DATA INTERPRETATION INTEGRATED WITH RESERVOIR CHARACTERIZATION OF MIANO AREA USING SEISMIC AND WELL LOG DATA

Abstract

In this dissertation, focus is placed on the structural interpretation of the Miano block-20 in order to demarcate the probable zone for the accumulation of hydrocarbons. This thesis work includes preparation of synthetic seismogram of Miano-09 well. Analysis of geophysical borehole logs provides one of the best approaches to characterizing rocks within boreholes. So Facies analysis is also done in order to identify lithologies. 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 and time and depth contours made from time and depth grid respectively. Facies modeling is one of the reliable tool for the confirmation of lithologies. In this dissertation, with the help of facies analysis of Miano-09 well, we came to the result revealing sand as the reservoir lithology. 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 hydro carbon by combination of the different logs results. In this dissertation the petrophysics is performed on the Miano-09 and Miano-lOwell and different zone of interest are marked where there is chance of the presence of the hydro carbon.
