2-DIMENSIONAL SEISMIC MODELLING AND RESERVIOR CHARACTERIZATION USING WELL DATA OF SINJHORO BLOCK, LOWER INDUS BASIN

Abstract

The present study relates to interpretation of seismic data, petrophysical analysis and colored inversion of Sinjhoro. 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 software Kingdom 8.8. The integrated study involves; structural interpretation of seismic data, time to depth conversion, synthetic seismogram, petrophysics, facies analysis and colored inversion. The seismic section shows Horst and Graben structure bounded by normal faults. The horizons were identified using formation 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
