Title
(EN) METHODS OF DRILLING WITH RESISTIVITY TOOLS
(FR) PROCÉDÉS DE FORAGE AVEC OUTILS DE RÉSISTIVITÉ
Abstract
(EN)
A method of electrically logging a section of a wellbore includes circulating an oil- based wellbore fluid comprising a conductive carbon material therein, the oil-based wellbore fluid having a conductivity of at most 0.01 S/m when measured at 20 kHz, within the wellbore while drilling the wellbore with a drill bit on a drill string; applying electrical current from a logging tool on the drill string above the drill bit; and collecting an electrical log of the portion of the wellbore that has had electrical current applied thereto.
(FR)
L'invention concerne un procédé de diagraphie électrique d'une section d'un puits de forage qui consiste à faire circuler un fluide de puits de forage à base de pétrole comprenant un matériau de carbone conducteur dans ce dernier, le fluide de puits de forage à base de pétrole ayant une conductivité d'au plus 0,01 S/m lorsqu'il est mesuré à 20 kHz, à l'intérieur du puits de forage pendant le forage du puits de forage avec un trépan sur un train de tiges de forage ; à appliquer un courant électrique à partir d'un outil de diagraphie sur le train de tiges de forage au-dessus du trépan de forage ; et à collecter un enregistrement électrique de la partie du puits de forage qui a eu un courant électrique appliqué à cette dernière.
