Abstract
A method for processing geophysical data. The method includes generating a model from geophysical data acquired at a receiver location and one or more boundary receiver locations. After generating the model, the method applies a forward modeling algorithm using information from the model to generate a modeled estimate of a direct ground roll between the receiver location and each boundary receiver location. The method then estimates a ground roll between a source location and each boundary receiver location. Using the modeled estimate of a direct ground roll between the receiver location and each boundary receiver location and the estimate of the ground roll between a source location and each boundary receiver location, the method applies interferometry between the estimate of the ground roll between the source location and each boundary receiver location and the modeled estimate of the direct ground roll between the receiver location and each boundary receiver location to generate an interferometric estimate of a ground roll between the source location and the receiver location. The method then removes the interferometric estimate of the ground roll between the source location and the receiver location from geophysical data acquired at the receiver location due to a source at the source location.
