THG Geophysics has just been awarded a patent for our Anvil Shear Wave Generator (ASWG).
The present patent application relates to a seismic energy source configured to generate shear wave energy in order to more accurately determine the distribution and orientation of fractures and other features in the subsurface among other uses. The present application is intended to be used as a shear wave seismic source during the collection of seismic profiles where at least one goal of the survey may be to determine shear wave velocity with depth. The device will produce a clean, repeatable shear wave for this land-based application. Its portable design makes it extremely practical for surveys where space is limited.
