摘要
A method for interval velocity analysis and reflector position determination from before stack seismic data includes developing a constant travel-time curve for a source and receiver pair. The process is repeated with other source and receiver pairs in order to generate a set of constant travel-time curves, and a series of the travel-time curves define an envelope curve for the reflector which is sharply focused at the true interval velocity. An additional embodiment provides a method for quantifying the velocities and permitting selection of the best velocity. Use of this selection method greatly enhances the speed and the overall operation accuracy.
