Title
(EN) METHOD OF SUBSEA CONTAINMENT AND SYSTEM
(FR) PROCÉDÉ DE CONFINEMENT SOUS-MARIN ET SYSTÈME ASSOCIÉ
Abstract
(EN)
A method and system of subsea containment which includes the steps of lowering the running tool into a subsea containment system, wherein the subsea containment system comprises an annular preventer, engaging the running tool to a target, closing the annular preventer, pulling up the target, and circulating fluid about the target. In a preferred method, rotating the running tool, cutting tubing, circulating the fluid at of the circulation line through the outlet, pulling the running tool out of the subsea containment system, and/or opening the annular preventer also performed. The target may be any item found in a subsea environment including a tubing hanger, a casing hanger, a tubing, a seal assembly, a component of a wellhead, or a component of the downhole completion.
(FR)
L'invention concerne un procédé et un système de confinement sous-marin qui comprend les étapes suivantes : abaisser l'outil de pose dans un système de confinement sous-marin, où le système de confinement sous-marin comprend un obturateur annulaire, engager l'outil de pose sur une cible, fermer l'obturateur annulaire, tirer la cible vers le haut, et faire circuler du fluide autour de la cible. Dans un procédé préféré, on effectue aussi la rotation de l'outil de pose, la coupe de tube de production, la circulation du fluide par la ligne de circulation au travers de la sortie, la traction de l'outil de pose hors du système de confinement sous-marin, et/ou l'ouverture de l'obturateur annulaire. La cible peut être n'importe quel élément présent dans un environnement sous-marin, y compris une suspension de tube de production, une suspension de tubage, un tube de production, un ensemble joint, un composant d'une tête de puits, ou un composant de la complétion de fond de trou.
