Seismic data processing transforms a large amount (often terabytes) of surface collected data into an accurate image of the subsurface. The key components are wavelet processing (e.g. noise attenuation, deconvolution, multiple attenuation) and imagin

We analyze how time migration mispositions events in the presence of lateral velocity variation by examining the impulse response of depth modeling followed by time migration. By examining this impulse response, we lay the groundwork for the developm

Even if the correct velocity is used, time migration mispositions events whenever the velocity changes laterally. These errors increase with lateral velocity variation, depth of burial, and dip angle θ. Our analyses of two model types, one with an i

True‐amplitude seismic imaging produces a three dimensional (3-D) migrated section in which the peak amplitude of each migrated event is proportional to the reflectivity. For a constant‐velocity medium, the standard imaging sequence consisting of

Powerful RISC-based workstations, capable of sustaining 10 MFLOPS or more on seismic algorithms, offer a new way of performing 3-D seismic computations. The algorithms are executed on a loosely-coupled set of workstations connected by a network to a
