Cette diagraphie consiste à mesurer la température dans le puits en fonction de la profondeur. On peut aussi mesurer le gradient de température ou différence de température entre deux profondeurs distantes de 1 m environ.  4, record 5, French, - thermom%C3%A9trie

Record number: 5, Textual support number: 2 OBS

La mesure des températures, lorsqu'il y a équilibre thermique entre le fluide qui remplit le forage et les terrains encaissants, peut donner, par exemple, la séparation de couches de conductibilités thermiques différentes, même si le forage est tubé. Elle donne aussi des indications sur la variation du degré géothermique.  5, record 5, French, - thermom%C3%A9trie

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 8, English, - electrical%20well%20logging
