Common problems encountered during the determination of the thermal conductivities of tight sandstones are rock specimen-to-heat source contact and complicated sample preparation. An experimental technique using an electromagnetic heat source solves

The possibility of using various types of electrical methods to locate oil or gas fields has been proposed in recent years. In an effort to quantify the anomaly to be expected with electrical sounding methods, average geoelectrical parameters have be

Induced polarization in pyritic sandstone arises in part from overvoltage effects and in part from electrolytic polarization. Because induced‐polarization measurements are commonly used to search for sulfides, the electrolytic polarization is an un

The electrical properties of rocks deep in the crust and in the upper part of the mantle may be studied with various electrical methods. The U. S. Geological Survey has conducted such studies using three methods: conventional galvanic resistivity sur
