INTEGRATED SEISMIC INTERPRETATION, STRATIGRAPHIC WELL CORRELATION, CRUSTAL SHORTENING, PETROPHYSICAL ANALYSIS, SEISMIC ATTRIBUTES ANALYSIS OF MISSA-KESWAL AREA

Abstract

For the interpretation of seismic data QZN-03, GNA-20 and GJN-20, three reflectors have been marked depending on prominent wiggles and named as Chorgali, Sakesar and Lockhart and basement on the basis of generalized stratigraphic column encountered in well Missa-1 lying on the given seismic line QZN-04. 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, velocity and depth contour maps are also prepared at a particular level to analyze the variations on the basis of time and depth. Surface contour maps are generated to get the 3D visualization of sub-surface structure in depth units. Stratigraphic well correlation of three wells Missa-1, Missa-2 and Misssa-3 to study the lateral extent of formations in the area and Petrophysical analysis is done for the conformation of hydrocarbon potential and volume of shale in the area. Structural Modeling of the interpreted digital geological crosssection is performed, using K-tron X-Works software application and Seismic Attribute analysis of seismic line QZN-03 which conforms the 2D structural interpretation.
