Abstract:
Methods of acquiring and processing seismic data using derivative sensors, such as strain sensors, that facilitate ground roll noise attenuation with seismic interferometry are disclosed. The methods use both seismic data and their spatial derivatives in computing ground-roll noises which are removed from processed seismic data.
