During the past decade, a radical change has taken place in the way seismic processing delivers a subsurface image. Previously, we employed a purely linear processing sequence, moving from data preconditioning to velocity estimation and culminating in a single time-migrated 3D image. The work of the contractor’s data processor was separate and distinct from that of the client’s interpreter.
