INTEGRATED SEISMIC INTERPETATION, PETROPHYSICAL ANALYSIS ALONG WITH AND SEISMIC ATTRIBUTE ANALYSIS OF MISSAKESWAL AREA

Abstract

MissaKeswal area is part of Potwar sub-basin of Upper Indus basin which is known for hydrocarbons and structural traps. Our work has been done on three lines, along with nine lines of group fellows. For the interpretation of seismic data the licensed softwares are used, two reflectors have been marked depending on prominent wiggles and named as Sakesar, Lockhart on the basis of generalized stratigraphic column encountered in well MissaKeswal-03 lying on the given seismic line GNA-15. Faults were also marked to examine the subsurface structure. Pop-up structures can be seen in the marked seismic section. Time sections are converted into the depth sections to view the real picture of the interpreted horizons. Time and depth contour maps of all Formations are also prepared at a particular level to analyze the variations on the basis of time and depth, Pop up(anticlinal) structure acts as a trap in the area, which is considered to be best for hydrocarbon accumulation. Petrophysical analysis is done which shows hydrocarbon and water saturation potential Crustal shortening calculated for all horizon which shows breakage and compressions in the structres due to faulting and salt of Pre-Cambrian age disturbed the basement creating popup structres. Seismic attribute analysis is used for the confirmation of 2D Seismic interpretation and it also highlights the zone of interest
