2D Deconvolution for OBC Data and for Internal Multiple Attenuation – Part 1 – Theory

A026 2D deconvolution for OBC data and for internal multiple attenuation – Part 1: Theory Abstract 1 We present herein the extension to the OBC case of a 2D pre-stack predictive deconvolution originally designed for surface-related multiple attenuation of streamer data. The formulation of this extension can also be applied for internal multiple attenuation. However while it is strictly exact for the OBC case it is probably rather an approximation for the internal multiples. Part 1 of this paper sets out the theory while the illustrations and application cases on synthetic and real data are brought together in Part 2
