Dokter, E. (author), Meles, G.A. (author), Curtis, A (author), Wapenaar, C.P.A. (author)A number of seismic processing methods, including velocity analysis (Sheriff and Geldart, 1999), make the assumption that recorded waves are primaries - that they have scattered only once (the Born approximation). Multiples then represent a source of coherent noise and must be suppressed to avoid artefacts. There are different approaches to...conference paper 2017

de Ridder, Sjoerd (author), van der Neut, J.R. (author), Curtis, A (author), Wapenaar, C.P.A. (author)Recently, a novel method to redatum the wavefield in the sub-surface from a reflection response measured at the surface has gained interest for imaging primaries in the presence of strong internal multiples. A prerequisite for the algorithm is an accurate and correct estimate of the direct-wave Green's function. However, usually we use an...conference paper 2016
