<p>METHOD OF SEISMIC PROCESSING INVOLVING CONVERTED P- OR S-WAVE DATA This invention relates to a method of increasing resolution of high-intensity amplitude events in seismic records provided by common midpoint collection methods (CMP) wherein nonsymmetrical travel paths of incident and reflected rays of the generated conventional waves are taken into account prior to trace stacking irrespective of dip or depth of the target reflector. In accordance with the invention, the converted phases of the conventional seismic wave, are processed as to define a series of common reflection point (CRP) coordinates each associated with a gather of converted traces as if a source associated with a given corrected trace was placed at each CRP and activated followed immediately by the relocation of a detector at the CRP and the reception of converted phases of the generated wave comprising the trace. Aspects of the invention interrelate properties of simultaneously collected conventional to converted traces (via a series of multicomponent detectors positioned along the line of survey) to improve the processing of the latter traces.</p> |
