Imaging overturning reflections by Riemannian Wavefield Extrapolation

  title={Imaging overturning reflections by Riemannian Wavefield Extrapolation},
  author={Paul C. Sava},
Correctly propagating waves from overhanging reflectors is crucial for imaging in complex geology. This type of reflections are difficult or impossible to use in imaging using one-way downward continuation, because they violate an intrinsic assumption of this imaging method, i.e. vertical upward propagation of reflection data. Riemannian wavefield extrapolation is one of the techniques developed to address the limitations of one-way wavefield extrapolation in Cartesian coordinates. This method… CONTINUE READING
