2D-Integrated Seismic Interpretation with Petrophysical Analysis, Rock Physics Based Facies Analysis and Velocity Modeling of MissaKeswal Area Upper Indus Basin of Pakistan

Abstract

MissaKeswal area is a part of Potwar sub-basin of Upper Indus Basin of Pakistan which is known for hydrocarbons and structural traps. The present study pertains to integrated seismic interpretation, petrophysical analysis coupled with rock physics techniques with facies analysis and subsurface velocity model building of MissaKeswal area. Work has been done on three lines along with nine seismic lines of group fellows along with their navigation and velocity data and well logs data of one well. .For Interpretation of seismic data Licensed softwares are used .Three formations have been marked on prominent wiggles and named as Lockhart ,Chorgali and Sakesar along with the faults marking to examine the subsurface structures. Pop-up structures can be seen in marked seismic section. Time and Depth contour maps are generated to view the resulting picture of interpreted horizons. Pop-up structures act as a trap in the area, which is considered best for hydrocarbon accumulation. Petrophysics and Rock physics analysis along with facies modeling are performed on MissaKeswal-03 and different zones of interest are identified where there is a chance of presence of hydrocarbon. Finally RSM Seismic Velocities have been used to generate a complex velocity model that has been used in 2D Seismic modeling
