ABSTRACT:
A one-return wave equation migration is used to extrapolate both down-going and up-going waves. Followed by a properly designed imaging condition, the partial image contributed form turning waves is correctly reconstructed. Numerical examples show that this method can significantly enhance definition of an overhanging salt boundary and a geological structure with vertical features.
