Abstract
The invention comprises a method for processing crosswell seismic data from a region of the earth's subsurface generated by transmitting a seismic signal from a plurality of source positions within at least one borehole within said region and detecting said seismic signal at a plurality of receiver positions in at least one borehole within said region. In a preferred embodiment, the seismic data is utilized to develop a model of raypaths traveled by seismic signals from said source positions to said receiver positions, and these raypaths are evaluated to determine if the seismic signal traveling along the raypaths traveled as a headwave for at least a part of the transmission path between the source position and the receiver position. Raypaths along which the seismic signals traveled as headwaves are deleted from the model, and a profile representing a property of the region of the earth's subsurface is then prepared utilizing the residual raypaths.
