ABSTRACT:
Disclosed is a method for estimating and correcting source and receiver statics contained in recorded and gathered seismic traces. Measurements based on the time of arrival of reflection and refraction signal components in the recorded and gathered traces are used to produce source-receiver statics estimates, which are in turn used to correctly time shift the individual traces of the gather for subsequent common depth point (CDP) gathering and stacking.
