Construction of algorithms for wavefield extrapolation in complex media
(Denisov M.S. Patrikeev P.V. Finikov D.B. )
The conventional seismic data processing methods are applied and usually provide reliable results in case of rather simple media. If the seismogeological conditions are complex, their efficiency can substantially reduce. This requires application of more flexible schemes that provide adequacy for a broader class of models. Particularly, if the known assumptions are violated, the ray-theoretical-based algorithms become incorrect. Alternative methods for wavefield computation and seismic data processing are to be applied to overcome the problem.......
