Pushing the limits of seismic imaging, part II: integration of prestack migration, velocity estimation, and AVO analysis

摘要

The author proposes an operator-driven prestack mi- gration scheme that is based on the synthesis of common focus-point (CFP) gathers. Each CFP gather represents the response of a synthesized source array that aims at the illumination of one subsurface grid point (focus point). The involved synthesis operator is referred to as the focusing operator.
