Improvements to surface picking techniques

摘要

A method for processing seismic data, characterized in that with a view to analyzing them as a function of at least four dimensions. Picking and/or picking propagation is carried out on at least one subset of data which corresponds to a collection of data sampled in three or two dimensions. The quantity or quantities which correspond to the other dimension or dimensions are fixed values. In applying a given projection law to at least one of the points highlighted by the picking and/or picking propagation to determine a point that corresponds to it in another subset corresponding to a collection of data sampled in the same dimensions for a different value of at least one quantity that corresponds to at least one other dimension.
