Unified elimination of 1D acoustic multiple reflection

Migration, velocity and amplitude analysis are the employed processing steps to find desired subsurface information from seismic reflection data. The presence of free-surface internal multiples can mask primary reflections for which many methods built. ability separate multiple is desirable. Connecting Marchenko theory with classical one-dimensional inversion allows understand process elimination as a data-filtering process. filter fundamental wave field, defined pressure particle that satisfy equation. field does not depend on or absence in backbone filtering computed measured without additional information. Two different multiples-free datasets obtained: either directly by applying In addition, known schemes follow main Numerical examples show source receiver ghosts, be removed simultaneously using conjugate gradient scheme. advantage equation wavelet need no pre-processing required. fact coefficients obtained an interesting feature could lead improved than would possible other methods.
