Title (EN) CALIBRATING ELECTROMAGNETIC CORROSION DETECTION TOOLS VIA CORE SATURATION
(FR) ÉTALONNAGE D'OUTILS DE DÉTECTION DE CORROSION ÉLECTROMAGNÉTIQUE PAR LE BIAIS D'UNE SATURATION DE NOYAU
Abstract:
(EN) Methods and devices used to calibrate EM corrosion detection tools may estimate the effects of the presence of a core on measurements to enable more accurate corrosion detection in the well line. The methods may involve sending voltages to a core of a well tool disposed in the well line to obtain signals while the core is in a saturated and unsaturated state. Subsequent measurements using the core may be calibrated using a constant resulting from the division of the signals achieved at the core in the saturated and unsaturated states.
(FR) L'invention concerne des procédés et des dispositifs permettant d'étalonner des outils de détection de corrosion EM permettant d'estimer les effets de la présence d'un noyau sur des mesures afin de permettre une détection de corrosion plus précise dans la ligne de puits. Les procédés peuvent consister à envoyer des tensions à un noyau d'un outil de puits disposé dans la ligne de puits afin d'obtenir des signaux pendant que le noyau est dans un état saturé et insaturé. Des mesures ultérieures à l'aide du noyau peuvent être étalonnées à l'aide d'une constante résultant de la division des signaux obtenus au niveau du noyau dans les états saturés et insaturés.
