摘要:
A computer-implemented method for processing seismic data includes the determining, from the seismic data, a first amplitude attribute map at a first image depth corresponding to a shallow attenuating body, and a second amplitude attribute map at a second image or target depth. The first and second amplitude attribute maps are then normalized, and a ratio map is determined based on a ratio of the normalized first and second amplitude attribute maps. The ratio map is scaled to yield a scale factor map, which is then applied to the seismic data to compensate for effects of shallow overburden attenuation.
