2D SEISMIC REFLECTION DATA INTERPRETATION AND PETROPHYSICAL 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. In this dissertation, focus is placed on the structural interpretation of the Miano Field Block-20 in order to demarcate the probable zone for the accumulation of hydrocarbons. This study attempts in 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, 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 is confirmed by fault polygon and time and depth contours maps. Petrophysics is the one of the most reliable tools for the confirmation of the types of the hydrocarbon and for marking the proper zone of the interest for the presence of the hydro carbon by combination of the different logs results. In this dissertation the petrophysics is performed on the Miano-10 well and different zone of interest are marked where there is chance of the presence of the hydro carbon. Rock properties of zone of interest are VSH is 22.5%, PHID is 10% and HC 56.3%.
