Abstract
An advanced 3D dip filtering technique is presented as a tool for revealing geological structures hidden below strong, internal multiples. The core of the method consists in decomposing the data into a few superposed planar events, this decomposition is achieved by an iterative loop of (automatic) picking in the Radon domain and non-linear optimization of the picked slopes and wavelets in the time-x-y domain. The events are classified and separated according to their dips and can be selectively reconstructed.
