Title (EN) HIGH FREQUENCY OR MULTIFREQUENCY RESISTIVITY TOOL
(FR) OUTIL A RESISTIVITE MULTIFREQUENCE OU HAUTE FREQUENCE
Abstract:
(EN) A system and method for determining material resistivity. A current of one or more frequencies is generated using a circuitry (225). The one or more frequencies is directed using one or more electrodes (215) into a surrounding material. The resistivity of the material surrounding the electrodes (215) and a drilling tool (210) is measured by detecting the current at the one or more frequencies.
(FR) L'invention concerne un système et un procédé destinés à déterminer une résistivité matérielle. Un courant à une ou plusieurs fréquences est généré, puis dirigé dans la matière environnante. Le courant est détecté à une ou plusieurs fréquences et la résistivité de la matière environnante est déterminée.
