Device And Method For Stable Least-Squares Reverse Time Migration

摘要

Method for generating a final image of a subsurface of the earth, including the steps of receiving (1000) measured seismic data d of the subsurface; selecting (1002) an objective function E that is function of a reflectivity r of the subsurface; and calculating (1012), in a processor, the reflectivity r based on the measured seismic data d, the objective function E, simulated data d, a modeling operator M from a reverse time demigration (RTDM) process and an imaging operator M T from a reverse time migration (RTM) process.
