In the 1990s, great improvements in instrumentation and computers resulted in light, compact geophysical field equipment and affordable computers with great speed and massive capacity. Geophysicists rapidly took advantage of that new capacity. Instead of being confined to using the modest number of sources and receivers common to 2D seismic processing, geophysicists began to use the tremendous number required for 3D processing, on a regular basis, in field operations.
