3D nonlinear stack enhancement: Correlation based stacking

Summary Stacking is a key step in seismic data processing that also plays a large role in interpretation. Results of stacking prestack gathers can be greatly enhanced by using a reference model as a coherence measure for noise attenuation. This 3D correlation based stacking approach allows an optimal mute to be designed for each gather prior to stacking. The result is the removal of unbalanced or coherent noise that may otherwise not be removed by deconstructive interference from stacking. The following results show that dramatic improvements are possible with this approach.
