Multiple suppression and wave separation
, by Lin Zhang
An inversion algorithm, which does multiple suppression and wave separation simultaneously,
is developed to process the 3-D marine seismic data recorded in a Walk-Away survey. The
key feature of the method is to use multichannel information to estimate multiple patterns
and to extract seabottom multiple-free downgoing waves and upgoing waves. The inversion is
performed by conjugate gradient method. The algorithm is tested on both synthetic data and
field data.
