Abstract
Usually, the interpretation of electrical anomalies in the electrical prospecting consists in solving the inverse potential problem. It is very difficult to solve the general problem of any resistivity distribution. Thus certain simplifying assumptions are often made about the types of resistivity distributions which occur in practice. Within the limits imposed by these assumptions, the standard curves and master curves have been calculated by many geophysicists.
In this paper, the author intends to explain the interpretation method by the analog computer which has been studied by the author and his assistants since 1954.
Many standard curves are obtained and the effects of topography and near-surface conditions are interpreted and the direct interpretation method is explained by using some electrical field surveys.
