Outlines seismic processing objectives and describes how the sequential steps of pre-processing, stacking and velocity analysis, migration and post-processing are used to generate the best possible image of the subsurface from recorded field data. Discusses the effect of each step on the overall sequence, with emphasis on the two-fold goal of improving the signal-to-noise ratio and locating seismic reflections with respect to their true spatial positions.
