Seismic surveying technique for the detection of azimuthal variations in the earth's subsurface
A method is described for surveying the earth's subsurface formations to determine azimuthal variations in the earth's subsurface comprising the steps of: imparting shear wave seismic energy into the earth with a first seismic source polarized in a first direction along a first seismic line of profile; recording the reflected shear wave seismic energy with a first geophone having a polarization matching the polarization of the first seismic source to produce a first shear wave record; imparting shear wave seismic energy into the earth with a second seismic source polarized in a second direction along a second seismic line of profile; recording the reflected shear wave seismic energy with a second geophone having a polarization matching the polarization of the second seismic source to produce a second shear wave record; processing the first and second shear wave records to produce a first and second shear wave section; and comparing the first and second shear wave seismic sections to determine azimuthal variations in the earth's subsurface.
