Abstract:
A method of producing a representation of a cross section of subterranean geologic formations comprising the steps of,recording a set of seismic traces along a line on the earth's surface, each trace being a waveform signal as a function of time which includes information about boundaries between subterranean geologic formations, determining basis vectors from said set of seismic data traces; performing at least one seismic processing operation on each of said basis vectors to produce processed basis functions; recording said processed basis functions; scaling the processed basis functions to produce scaled processed basis functions; summing said scaled processed basis functions to produce a transformed set of seismic data traces, and displaying said transformed set of seismic data traces on an x-y grid, whereby an improved visual representation of a cross section of the earth's crust is presented.
