Examples of multiple suppression of land seismic data

Multiples attenuation sometimes necessary of a land seismic processing flow as seismic imaging techniques assume that the input data are free of multiples. The presence of multiples leaves us with spurious images and amplitudes. Primary events may create outstanding multiples to perplex and perturb seismic interpreters. The removal of multiples becomes necessary to obtain true image of the subsurface. The diversity of multiple attenuation methods available and continuous rapid advance of multiple attenuation process in general can make it difficult to decide which technique is best suited to our particular data set. There is however no method or group of methods that works in all area.
