Coherency calculations in the presence of structural dip

  title={Coherency calculations in the presence of structural dip},
  author={Kurt J. Marfurt and V. Sudhaker and Adam Gersztenkorn and Kelly D. Crawford and Susan E. Nissen},
We have used crosscorrelation, semblance, and eigenstructure algorithms to estimate coherency. The first two algorithms calculate coherency over a multiplicity of trial time lags or dips, with the dip having the highest coherency corresponding to the local dip of the reflector. Partially because of its greater computational cost, our original eigenstructure algorithm calculated coherency along an implicitly flat horizon. Although generalizing the eigenstructure algorithm to search over a range… CONTINUE READING
