2D SEISMIC REFLECTION DATA INTERPRETATION, PETROPHYSICAL ANALYSIS AND FACIES ANALYSIS OF SANJHORO AREA SANGHAR DISTRICT (SINDH, PAKISTAN)

Abstract

The present study relates to integrated seismic and rock physics analysis of Sinjhoro with special techniques. The area is part of southern Indus basin. The work is carried out on 3 seismic lines along with petrophysical logs of Chak 66-01 , using Kingdom software. The integrated study involves, structural interpretation of seismic data , time to depth conversion, synthetic seismogram , petrophysics ,facies analysis and well correlation. The seismic section shows Horst and graben structure bounded by normal faults . The horizons were identified using f0n11ation tops from wells and their depth were confirmed through correlation with synthetic seismogram generated from sonic and bulk density logs. Time, depth and horizon contour maps of the horizons of interest have been generated to understand the spatial geometry of the structures and polygon were formed, and high concentration of shale clearly shows that there is only a thin reservoir present
