(EN) METHODS AND SYSTEMS FOR A TEMPORARY SEAL WITHIN A WELLBORE
(FR) PROCÉDÉS ET SYSTÈMES POUR UN JOINT TEMPORAIRE DANS UN PUITS DE FORAGE
Abstract
(EN)
A temporary seal within a wellbore. More specifically, a temporary seal within casing that limits the flow of fluid through the casing until the temporary seal is released.
(FR)
L'invention concerne un joint d'étanchéité temporaire à l'intérieur d'un puits de forage. Plus particulièrement, l'invention concerne un joint temporaire disposé à l'intérieur d'un tubage, lequel joint temporaire limite la circulation de fluide à travers le tubage jusqu'à ce que ledit joint temporaire soit retiré.
