Title
(EN) ROTATABLE VALVE FOR DOWNHOLE COMPLETIONS
(FR) SOUPAPE ROTATIVE POUR COMPLÉTIONS DE FOND DE TROU
Abstract
(EN)
Method and apparatus for performing a series of downhole operations. The method can include conveying a work string with an integrated valve into a wellbore. As the work string with the integrated valve is conveyed into the wellbore, the valve can be in a first operation mode. When the valve is located within the wellbore, the valve can be adjusted to a different operation mode by selectively rotating at least a portion of the valve without longitudinal movement of the valve relative to the wellbore.
(FR)
L'invention porte sur un procédé et sur un appareil pour réaliser une série d'opérations en fond de trou. Le procédé peut comprendre le transport d'un train de tiges de travail avec une soupape intégrée dans un puits de forage. Lorsque le train de tiges de travail avec la soupape intégrée est transporté dans le puits de forage, la soupape peut être dans un premier mode de fonctionnement. Lorsque la soupape est disposée à l'intérieur du puits de forage, la soupape peut être réglée à un mode de fonctionnement différent par rotation sélective d'au moins une partie de la soupape sans mouvement longitudinal de la soupape par rapport au puits de forage.
