Disregarding their possible use in imaging, surface multiples are primarily still dealt with by 3D SRME (convolutional and/or wave equation modelling in different ratios) despite its well-documented shortcomings related to the need for adaptive subtraction and its well-known limitations in shallow water regimes. However, where necessary, this single prediction-subtraction process can easily be augmented by other methods generating additional predictions and then used in a simultaneous multi-model subtraction method, or the process can be completely replaced by an inversion algorithm (e.g. EPSI and its variants).

OtherIn exploration seismology, most imaging and inversion approaches would not make use of multiple reflections, as such they have long been considered as noise, simply to be removed from the seismic data in a pre-processing step. However, an alternative view is that multiples should be included in imaging, since multiples, along with primary reflections, are an integral part of the physics of wave propagation that describes our seismic response.
