Record number: 1, Textual support number: 1 DEF

A special type of electrical well log in which the conductivity of the formation is measured ... Eddy currents are induced in the formations by a transmitter coil through which an alternating current is circulated. The eddy currents set up magnetic fields that induce voltages in a receiver coil. These voltages are amplified and recorded on the surface.  4, fiche 1, Anglais, - induction%20log

The induction survey is usually taken in conjunction with a regular electric survey (ES), and thus the abbreviation commonly used for an induction survey is I-ES.  4, fiche 1, Anglais, - induction%20log

... a method wherein the conductivity or its reciprocal, the resistivity, of the formation is measured by means of induced currents without the help of electrodes.  2, fiche 2, Anglais, - induction%20logging

Record number: 2, Textual support number: 1 CONT

Induction logging is an alternating current method, the current and potential electrodes being replaced by a transmitter coil and a receiving coil. Usually the transmitter current is held constant and the emf induced in the receiver then represents the resistivity of the formation.  3, fiche 2, Anglais, - induction%20logging
