Wave field autofocusing and applications to multidimensional deconvolution and imaging with internal multiples
One of the most challenging tasks of exploration geophysics is to build a quantitatively accurate image of the structures inside the Earth from reflection data measured at the Earth's surface. When the subsurface is structurally complicated, accurate images are needed to locate energy sources, such as hydrocarbon reservoirs. Conventional migration algorithms rely on the single-scattering assumption. This restrictive assumption requires that the recorded data do not include waves that have bounced multiple times between layers before reaching the receivers. Standard imaging algorithms incorrectly ...
