3D Predictive Deconvolution for Wide-azimuth Gathers

Usual pre-stack predictive deconvolution solutions for multiple attenuation are either monochannel or designed for 2D gathers. These existing 1D /2D solutions are suboptimal for today's modern acquisition geometries, which allow the construction of 3D, wide azimuth pre-stack collections. We therefore present a 3D pre-stack predictive deconvolution algorithm suited to today's WAZ HD HR gathers. It targets the attenuation of the multiples (either surface or internal) in horizontally layered media, and is applied on densely sampled, wide-azimuth gathers, from either marine, land, or OBC surveys (cross-spread gathers, receiver or shot gathers, mega bin, macro bin,...). As usual with the predictive deconvolution algorithms, it is the most useful for short to medium period multiples.
