Title (EN) SYSTEM AND METHOD FOR REGULATING PRESSURE WITHIN A WELL ANNULUS
(FR) SYSTÈME ET PROCÉDÉ PERMETTANT DE RÉGULER LA PRESSION À L'INTÉRIEUR D'UN ESPACE ANNULAIRE D'UN PUITS DE FORAGE
Abstract: front page image
(EN)Pressure within a subsea well is managed as temperature within the well fluctuate. The management of the pressure mitigates stress to the structure of the well caused by the pressure. To manage the pressure, fluid is received from and/or provided to the well to reduce and/or increase pressure within the well.
(FR)La présente invention porte sur la gestion de la pression à l'intérieur d'un puits de forage sous-marin à mesure que la température à l'intérieur du puits de forage varie. La gestion de la pression atténue la tension sur la structure du puits de forage provoquée par la pression. Afin de gérer la pression, un fluide est reçu en provenance du puits de forage et/ou fourni au puits de forage afin de réduire et/ou d'augmenter la pression à l'intérieur du puits de forage.
