IM-4 3D POST-STACK MULTIPLE ATTENUATION VIA PATTERN RECOGNITION – A LAND CARBONATE CASE STUDY Summary 1 This paper discusses a de-multiple technique that aims at removing only the multiple energy (surface related and internal) associated with specified primary events and generated by an identified mechanism. A “model” of the targeted noise event is obtained post-stack using a simple 1D earth assumption. Removal of the targeted multiple is achieved via a pattern recognition technique implemented in the frequency-space (f-xy) domain. The performance of this multiple elimination methodology is demonstrated using 3D seismic data from a land carbonate environment. A two-step process
