Abstract:

A seismic data processing method in which seismic traces (each trace containing a signal resulting from reflection of a seismic signal at a location within the earth, and each trace being associated with at least one point in a two-dimensional spatial grid (x,y)) are subjected to Fourier transformations, the coefficients of the Fourier-Transformed traces are subjected to a recursive KF migration operation, and the migrated traces are thereafter inverse-Fourier-transformed. When displayed, the processed seismic data accurately represents the position within the earth of whatever caused the reflection. The method may be employed to process stacked seismic traces, each associated with a single point (x,y) in the grid, or may be employed to process unstacked seismic traces, each associated with both a seismic source location (x. sub. s,y. sub. 5) and a different seismic receiver location (x. sub. r,y. sub. r) in the grid.
