ABSTRACT:
Methods and apparatus for processing vibrative seismic data. Baseplate phaselock vibrative energy, reaction mass phaselock vibrative energy and ground force phaselock vibrative energy are transmitted into the earth using a land vibrator and the reflections of the transmitted waves recorded. The source signature of the land vibrator is computed for each type of vibrative energy and the source signature is correlated with the corresponding recorded data to produce an image of the subsurface. Regardless of the type of phaselock vibrative energy generated into the subsurface, the images of the subsurface produced by the correlation of the source signature and the recorded data are substantially the same. The correlated data may be then analyzed to yield useful information related to the characteristics of the subsurface.
