Title
(EN) METHOD FOR DETERMINING RESERVOIR PROPERTIES IN A FLOWING WELL
(FR) PROCÉDÉ POUR DÉTERMINER LES PROPRIÉTÉS DE RÉSERVOIR DANS UN PUITS JAILLISSANT
Abstract
(EN)
A technique facilitates monitoring a reservoir property in a flowing well (22). The technique utilizes deployment of a sensor system (42,66) along the wellbore outside of a wellbore commingled flow region. The sensor system is utilized while the well is flowing during production, and the measured formation property can be used to determine/evaluate production and other well characteristics.
(FR)
La présente invention concerne une technique qui facilite la surveillance d'une propriété de réservoir dans un puits jaillissant (22). La technique utilise le déploiement d'un système de capteurs (42, 66) le long du puits en dehors d'une région de puits d'écoulement mélangé. Le système de capteurs est utilisé lors de l'écoulement du puits pendant la production, et la propriété de formation mesurée peut être utilisée pour déterminer/évaluer la production et d'autres caractéristiques du puits.
