Title (EN) PASSIVE MONITORING SYSTEM FOR A LIQUID FLOW
(FR) SYSTÈME DE SURVEILLANCE PASSIVE D'UN ÉCOULEMENT DE LIQUIDE
Abstract: front page image
(EN)A passive liquid flow monitoring system includes a monitoring device made of a liquid-soluble material in which coded transponders are releasably retained. The monitoring device may be deployed proximate a region of interest in a hydrocarbonproducing well. Characteristics of a liquid flow in the region of interest may be determined based upon detection of transponders that are released from the monitoring device when the monitoring device is exposed to the liquid flow.
(FR)L'invention concerne un système de surveillance passive d'un écoulement de liquide qui comprend un dispositif de surveillance constitué d'un matériau soluble dans les liquides dans lequel des transpondeurs codés sont retenus temporairement. Le dispositif de surveillance peut être déployé à proximité d'une région d'intérêt dans un puits produisant des hydrocarbures. Les caractéristiques d'un écoulement de liquide dans la région d'intérêt peuvent être déterminées sur la base de la détection des transpondeurs qui sont libérés du dispositif de surveillance quand ce dernier est exposé à l'écoulement de liquide.
