Abstract

Multiple attenuation is a long standing problem in reflection seismic industry. There are two related aspects, multiple predictions and multiple attenuation. The attenuation of multiple reflections in surface seismic data has been a high priority in seismic industry for many years. Much partial solution exists that are able to tackle the problem in particular circumstances. There is however no method or group of methods that work in all area. In the history of multiple removal, algorithms have been based on two differentiating properties i.e. moveout and predictability. If primaries and multiples show different moveout behavior, algorithms are available that allow separation of primaries and multiples in a transform domain.
