ABSTRACT:
A method for measuring properties of earth formations surrounding a borehole and, particularly, properties of the invaded zone of the formations. A short pulse of electrical energy is applied at a transmitter location, and signals are induced at a plurality of receiver locations. The polarities of the initial portions of the signals detected at the receiver locations are used in determining properties of the formation invaded zone, particularly its thickness and its conductivity as compared to the virgin formations.
