Review of semi-automatic velocity analysis techniques

Abstract

A large number of semi-automatic velocity techniques have been developed in the past few years. The principle of such techniques is based on computerized approximations to the familiar delta-T analysis normally done by hand. The success of these programs depends largely on the exact mathematics of the program, the quality of the data, and most important, the form of display used to present results. This review will attempt to show results from a number of different programs using different mathematical methods and various types of displays. The reader is referred to various published papers such as: (1) Schneider, Backus, et al, 1966; (2) Garotta and Michon, 1967; and (3) Taner and Koehler, 1969; for the detailed calculations of a few of these methods.
