Title: Seismic exploration method - summing reflection signals for simulating strata response to wave energy
IPC: G01V1/24
Filed: 1978-02-06
Abstract: Seismic exploration method, based on spherical seismic waves, produces reflection signals in many receiver positions which are spaced over an area of large dimension relative to the seismic wavelength.
