Abstract
Un système détanchéité installé hydrauliquement comprend un ensemble supérieur sensible à la pression dun fluide de fracturation afin dassurer un joint supérieur pour la zone dintérêt. Il comprend également un ensemble inférieur réagissant directement à la pression du fluide de fracturation pour permettre au fluide de sécouler dans la zone dintérêt, et réagissant indirectement à la pression du fluide de fracturation par lintermédiaire dune chambre inférieure hydrauliquement étanche autonome afin dassurer un joint inférieur pour la zone dintérêt. En augmentant et en diminuant la pression du fluide de fracturation, le système détanchéité installé hydrauliquement peut être utilisé alternativement pour étanchéifier et isoler la zone dintérêt, et desceller et extraire ou déplacer facilement le système détanchéité.
