Abstract: The invention is a method of geophysical exploration using seismic methods. The receivers and the source are rotated to one another, such that the orthogonal excitations of the seismic source are readily differentiated. The differentiation of the differently excited energies can be accomplished in devolving the seismic events and reception of those events into a radial-tangential coordinate system for each receiver source pair. The differentiation of the differently aligned energies allows a greater insight into the volumetric study of the strata making up the prospect volume.

Abstract: The present invention provides a system for, and method of determining anisotropy in a stratum using scattered horizontal shear and vertical shear modes. The method includes transforming seismic energy wave generated by a seismic energy source and received by seismic receivers into radial/transverse coordinate space, determining a seismic energy wave corridor along a radial path between the seismic energy source and the seismic receivers, and gathering seismic data received by the seismic receivers within the corridor wherein the data includes horizontal and vertical shear components.

Abstract: The present invention provides a system for, and method of determining vertical fractures in a stratum using scattered horizontal shear and vertical shear modes. The method may include segregating first order horizontal and vertical shear modes of a seismic energy wave into second order horizontal and vertical shear modes, defining a seismic energy wave corridor along a radial path between a seismic energy source and seismic receivers, and gathering seismic data received by the seismic receivers within the corridor, the data including the second order horizontal and vertical shear modes.
