In the United States the applications of electrical prospecting have been few. Thus it might appear superfluous to discuss exhaustively the method. On the other hand it has been applied quite extensively and successfully in the Eastern Hemisphere, particularly by French geophysicists, under the leadership of Conrad and Marcel Schlumberger.
