Title
(EN) WELLBORE ISOLATION BARRIER MONITORING
(FR) SURVEILLANCE DE BARRIÈRE D'ISOLEMENT DE PUITS DE FORAGE
Abstract
(EN) A method of evaluating a stress state of a wellbore isolation barrier with an evaluation application receiving a data set, obtained from wellbore sensors, from a remote data source by one or more communication methods. The data set comprises periodic wellbore data indicative of the stress state of the wellbore isolation barrier. The evaluation application may determine a modeled stress state of the wellbore isolation barrier by evaluating a data set consisting of the received data. The evaluation application may generate an alert if the model stress state exceeds a user threshold.
(FR) L'invention concerne un procédé d'évaluation d'un état de contrainte d'une barrière d'isolement de puits de forage à l'aide d'une application d'évaluation recevant un ensemble de données, obtenu à partir de capteurs de puits de forage, à partir d'une source de données à distance par un ou plusieurs procédés de communication. L'ensemble de données comprend des données de puits de forage périodiques indiquant l'état de contrainte de la barrière d'isolement de puits de forage. L'application d'évaluation peut déterminer un état de contrainte modélisé de la barrière d'isolement de puits de forage par évaluation d'un ensemble de données constitué des données reçues. L'application d'évaluation peut générer une alerte si l'état de contrainte de modèle dépasse un seuil d'utilisateur.
