The recent advent of fast, inexpensive personal computers (PCs) is revolutionizing modern seismic depth imaging. Prices for supercomputer-style computation, graphical display, and data storage, halve every 18 months.

Modern networking technologies couple inexpensive PCs into powerful clusters that easily solve problems once thought intractable on far more expensive machines. It is now feasible to utilize accurate, computationally intensive algorithms to produce subsurface images that are vastly superior to those produced with current Kirchhoff technology. Graphic capabilities provide a new interpretative processing environment for improved velocity analysis and earth model estimation. This article discusses these new advances and the technologies they...
