WebInduction logs are designed to measure the conductivity of rock formations by using the electromagnetic principles outlined by Faraday, Ampere, Gauss, Coulomb and unified in a single theory by James Maxwell in 1864. The process involves the interaction of magnetic and electric fields: WebAs a result, the induction log is most accurate at high conductivities and with resistive invasion. However, below about 1 ohm-m skin effect becomes important. Practical induction- logging tools use arrays of several coils, designed to achieve a specific focusing and depth of investigation.
