Creators

Description

A bore-hole goes through sub-soil formations and is tubed by means of a tubing maintained in position by a concrete layer. A well logging probe is suspended in that bore-hole by a cable. The latter provides the connection between the equipments mounted in the probe and the ground-level equipments

Abstract (French)

Un puits de forage traverse des couches de terrain et est tube a l'aide d'un tubage maintenu en place a l'aide d'une couche de ciment. Dans le trou est suspendue une sonde de diagraphie a l'aide d'un cable. Ce cable sert a assurer la liaison entre les equipements qui se trouvent dans la sonde et les equipements de surface
