Abstract

Processing sequences based on CRS-stack attributes has been employed for complex geological structures with the aims is to gain an improved stacked section quality, to use straightforward way to generate velocity-depth model and to take the advantages of minimum aperture Kirchhoff migration method. The CRS attributes which required during stacking could be utilised for further processing such as velocity model building and migration aperture determination. NIP-wave tomography that utilised CRS attributes offers promising, efficient and accurate way to derive velocity model because kinematic information picked from stacked section with improved signal-to-noise ratio. Besides that, CRS attributes can be used to predict stationary point and Fresnel zone width which helpful for migration process. Application of CRS-stack, NIP-wave tomography and minimum-aperture Kirchhoff migration to real data example has gained interesting results.
