Abstract
P027 Sesimic Reflector Characterization by a Multiscale Detection-Estimation Method M. Maysami* (University of British Columbia) & F.J. Herrmann (University of British Columbia) SUMMARY Seismic transitions of the subsurface are typically considered as zero-order singularities (step functions). According to this model the conventional deconvolution problem aims at recovering the seismic reflectivity as a sparse spike train. However recent multiscale analysis on sedimentary records revealed the existence of accumulations of varying order singularities in the subsurface which give rise to fractional-order discontinuities. This observation not only calls for a richer class of seismic reflection waveforms but it also requires a different methodology
