Abstract

MultiFocusing technology allows obtaining better images in cases of low fold data, poor signal- to- noise ratio or sparse 3D acquisition. Local parameters of the observed wavefield in pre-stack seismic records that are estimated during the MultiFocusing process are of great interest for many seismic applications such as signal enhancement, velocity model building and such. In the presence of nonhyperbolic arrival times, a local common offset MultiFocusing approximation for the traveltime stacking surface description is used to accurately approximate the traveltimes of seismic events. We present this signal enhancement scheme and demonstrate its efficiency.
