ABSTRACT:
The present invention provides an accelerated weight drop for use as a seismic energy source, a method for operating an accelerated weight drop for use as a seismic energy source, and a seismic survey system including the accelerated weight drop. The accelerated weight drop, among other elements, may include a striker positionable over a surface, a compressed gas spring configured to drive the striker toward the surface thus creating seismic waves within the surface, and a cushioning means positioned proximate the compressed gas spring for dissipating reflected energy. In this embodiment the striker is slidably coupled to the compressed gas spring.
