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).@en
