PDF-RESISTIVITY LOG

62 ELECTRICAL AND RESERVOIR CHARACTERISTICS In practical terms I found that an apparent resistance reading of 500 footohms for a 20ft electrode separation recorded over ground or glacial mo. The resistivity may be used to determine the dielectric breakdown dissipation factor moisture content mechanical continuity and other important properties of a material The volume resistivity of some insulators such as sapphire and Teflon can be as Chapter 12. Electrical Methods. Geologic Resistivity 101. Resistivity surveying investigates variations of electrical resistance, by causing an electrical current to flow through the subsurface using wires (electrodes) connected to the ground.. Charles .
