ABSTRACT:
A method of seismic analysis is disclosed for identifying subterranean features that in one embodiment uses a coherence analysis for improved seismic data interpretation such as improved accuracy of variables for use in velocity models. The method may be used while analyzing seismic data to produce an earth model wherein the analysis is preferably applied at each level for the model. In another embodiment of the present invention, the coherence analysis is applied as a function of the seismic processing sequence to improve the variables associated therewith. With respect to a subterranean location of interest, azimuth ordered gathers may be used to identify subterranean features such as fault/fracture patterns. In another embodiment, offset ordered coherence analysis is used to form an optimum stack at the subterranean location of interest. In another embodiment of the invention, factors such as P, S, G, and fluid factor are derived from coherence data from which instantaneous envelope gathers are computed and divided into angle gathers.
