Geostatistical filtering of 4D seismic data: methods and benefits
Résumé
Geostatistical filtering aims at removing noise and artifacts on seismic volumes by decomposing a signal into spatially independent structures (signal + artifact(s) + noise) and filtering out the undesirable one(s). Multivariate methods allow the identification of common spatial behavior between different seismic volumes, as time-lapse seismic. This paper shows the methodology and benefits of using geostatistical filtering on 4D vintages.
