Title
(EN) WELLBORE LEAK DETECTION SYSTEMS AND METHODS OF USING THE SAME
(FR) SYSTÈMES DE DÉTECTION DE FUITE DE PUITS DE FORAGE ET LEURS PROCÉDÉS D'UTILISATION
Abstract
(EN)
A leak detection system for a wellbore. The leak detection system includes: (1) at least one sensor configured to be positioned outside of a casing of the wellbore; (2) an interrogation system for sending signals to, and receiving signals from, the at least one sensor; and (3) an optical lead cable disposed between the interrogation system and the at least one sensor. A method of detecting a fluid leak in a wellbore is also disclosed.
(FR)
L'invention porte sur un système de détection de fuite pour un puits de forage. Le système de détection de fuite comprend : (1) au moins un capteur configuré de façon à être positionné à l'extérieur d'un tubage du puits de forage ; (2) un système d'interrogation pour envoyer des signaux au ou aux capteurs, et pour recevoir des signaux à partir de ceux-ci ; et (3) un câble de conducteur optique disposé entre le système d'interrogation et le ou les capteurs. L'invention porte également sur un procédé de détection d'une fuite de fluide dans un puits de forage.
