|4933912||Three dimensional seismic prospecting method|
A 3-D seismic prospecting method is provided which employs an areal array of sources and receivers by which seismic traces are generated. The areal array is segregated into a plurality of shells and angularly separted sections from which a preselected num...
|4635238||Data processing method for correcting P and S wave seismic traces|
A method of processing seismic data enables correlation of P and S-wave seismic traces. First, P and S-waves are transmitted into the subsurface. The two-way vertical travel times are then measured for each wave to different depths so as to yield two sets...
