<p>A method is provided for performing multi-dimensional deconvolution of geophysical data, wherein the method is characterised by using exact boundary conditions 22, 24. The method may comprise using a forward solver of the wave equation in combination with the boundary conditions. The boundary conditions may comprise a recording surface and an emitting surface. Other aspects of the invention relate to methods of redatuming a wavefield by means of finite-difference (FD) injection or injecting the wavefield as source terms in the wave equation. Another relates to a method of redatuming receivers to a different depth using FD injection and a final one relates to a method of performing multiple suppression by redatuming a wavefield using FD-injection and using exact boundary conditions to achieve multiple suppression.</p> |
