SEISMIC DATA PROCESSING USING MATCHING FILTER BASED COST FUNCTION OPTIMIZATION

摘要

A method for processing seismic data from a subsurface using least squares migration (100) or wave equation migration velocity analysis (200) over a cost function comprising a function of a matching filter by iteratively updating the reflectivity model velocity model to yield an updated reflectivity model or updated velocity model that matches the observed seismic data (110, 210).
