Abstract
A vibrator-coupled ground filter improves seismic data recorded during a seismic operation. This filter is based on a ground model that takes into consideration the vibrator system, the coupling system between the baseplate and captured ground, and the coupled ground system. Using acceleration data from the baseplate and the reaction mass, the ground model can be used to derive particular variables for the ground model to help characterize the system. Using the derived variables in a ground filter, the recorded seismic data can be corrected to remove errors in the trace data produced by typical assumptions.
