Multi-vintage coherent noise attenuation in time-lapse processing
Multi-vintage coherent noise attenuation in time-lapse processing
4D seismic processing is designed to minimize non-repeatable noise while preserving real 4D signal. Coherent noise, such as from surface and interbed multiples, has different character from one vintage to another. Mitigating for these unwanted effects in a vintage-independent manner leads to suboptimal 4D ...
