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, record 3, English, - 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, record 3, English, - induction%20log

Electrical well logging was introduced by the Schlumberger brothers in the late 1920s as an extension of the resistivity method of electrical prospecting ... the resistivity scenes obtained with electrodes lowered into a borehole when plotted against depth, gave a 'log' of the stratigraphical changes, and in particular provided an accurate depth of each rock layer below the surface.  1, record 4, English, - electrical%20well%20logging

The resistivity log curves from a multi-electrode sonde designed to focus the surveying current radially through the rocks in a horizontal, disk-shaped pattern. This permits sharp definition of bed boundaries and improved measurement of resistivity.  2, record 7, English, - focused%2Dcurrent%20log

The first focused measurements were found on the market in 1950 under the name Laterologs. Since then, Laterologs have evolved from the first generation called Laterolog 3 (LL3) into Laterologs 7 (LL7) Laterologs 8 (LL8) and dual Laterologs (LLd).  3, record 7, English, - focused%2Dcurrent%20log

Type de diagraphie électrique souvent utilisée quand on fore avec un fluide de forage à l'eau salée. Le latérolog mesure la résistance de la formation, mais parce que le courant appliqué est centré sur une petite zone, on peut faire d’avantage de mesures sélectives.  3, record 7, French, - diagraphie%20focalis%C3%A9e%20de%20r%C3%A9sistivit%C3%A9

La nécessité pour une mesure de résistivité indépendante de la résistivité de la boue, du diamètre du sondage et de l’épaisseur des couches a été ressentie très tôt. Il a fallu cependant attendre 1950 pour avoir les premières mesures focalisées commercialisées sous le nom de Laterologs.  2, record 7, French, - diagraphie%20focalis%C3%A9e%20de%20r%C3%A9sistivit%C3%A9
