General Note	Title from title screen (viewed September 15, 2014).
	"New techniques in direct-current resistivity exploration."
	"Formulas defining two types of modified Dar Zarrouk curves are used to invert Schlumberger sounding curves, uring an iterative procedure. The number of layers, which is equal to the number of points on the inverted curve, is reduced by automatically smoothing the corresponding DZ curve."
Bibliography	Includes bibliographical references (pages 37-39).
Subject - LC	Earth resistance (Geophysics) -- Data processing.
	Electric currents.
