  • Method for estimation of propagation paths for seismic signals
    Patent number: 6778907
    Abstract: In one embodiment, the invention includes a method for estimating seismic signal propagation raypaths from seismic source locations through a subsurface formation to seismic receiver locations. Raypaths are determined which minimize the value of an expression which is a function of travel time and distance between a source location and a receiver location. The value of the expression depends on the value of a parameter which balances the weighting of travel time and distance in the expression.
