Title (EN) SYSTEMS AND METHODS FOR MONITORING A WELL
(FR) SYSTÈMES ET PROCÉDÉS DE CONTRÔLE DE PUITS
Abstract: front page image
(EN)A method for identifying fluid migration or inflow associated with a wellbore tubular, comprises measuring strain of the wellbore tubular with a system comprising at least one string of interconnected sensors that is arranged such that the sensors are distributed along a length and the circumference of the wellbore tubular; establishing a baseline that is a function of steady state strain measurements within a first time period; and identifying fluid migration or inflow where strain measurements substantially deviate from the baseline within a second time period.
(FR)L'invention concerne un procédé d'identification de migration de fluide ou d'écoulement entrant en association avec un matériel tubulaire de puits de forage. On mesure la contrainte de ce matériel au moyen d'un système qui comprend au moins un chapelet de capteurs interconnectés disposés de sorte que les capteurs soient distribués sur une longueur et la circonférence du matériel tubulaire en question; on établit une ligne de référence qui est fonction des mesures issues de contrainte en continu durant une première période; et on identifie la migration de fluide ou l'écoulement entrant là où les mesures de contrainte s'écartent sensiblement de la ligne de référence durant une seconde période.
