Summary
The determination of the gross velocity distribution in the ground from CDP reflection data depends primarily on the determination of the velocity producing maximum coherency in the stacked data. This stacking velocity is a mathematical quantity which has no physical significance. The interval and average velocities describe meaningful physical parameters and are related to the maximum coherency stacking velocity through the r.m.s. velocity. The relationship between these velocities is illustrated. The limitations to the horizontal resolution of the velocity tool are discussed.
The CDP-derived velocities are subject to numerous errors; some errors are generated during the acquisition and processing stages and during the wave propagation in the ground, others arise from geological complexities or are subjective in nature, etc. These errors are discussed and methods of their estimation and, where appropriate, of their treatment are given. The main applications of the CDP-derived velocities are briefly reviewed.
