OSTI ID:5802454
This patent describes a method of seismic exploration employing seismic sources s{sub j} having at least two linearly independent lines of action j with respect to a survey line and seismic receivers r{sub i} having at least two linearly independent lines of action i with respect to the survey line. It comprises imparting seismic energy into the earth with seismic sources s{sub f}; recording the earth's response to the imparted seismic energy with receivers r{sub i}; collecting a concord of seismic signals {phi}{sub ij}, wherein the seismic energy imparted by seismic source s{sub j} are recorded by seismic receiver r{sub i}; and processing the full concord of seismic signals {phi}{sub ij} consisting essentially of diagonalizing the amplitude values of the concord of seismic signals {phi}{sub ij}, as a concord, and obtaining a diagonalized concord of seismic signals {phi}{sub cm}, wherein the amplitude values of the cross component seismic signals {phi}{sub ij} of the concord of seismic signals are substantially reduced to zero.
