Interferometric imaging condition for wave-equation migration

  title={Interferometric imaging condition for wave-equation migration},
  author={Paul C. Sava},
The fidelity of depth seismic imaging depends on the accuracy of the velocity models used for wavefield reconstruction. Models can be decomposed in two components corresponding to large scale and small scale variations. In practice, the large scale velocity model component can be estimated with high accuracy using repeated migration/tomography cycles, but the small scale component cannot. When the Earth has significant small-scale velocity components, wavefield reconstruction does not… CONTINUE READING
