Title
(EN) THERMOSET SWELLABLE DEVICES AND METHODS OF USING IN WELLBORES
(FR) DISPOSITIFS POUVANT GONFLER THERMODURCISSABLES ET LEURS PROCÉDÉS D'UTILISATION DANS DES PUITS DE FORAGE
Abstract
(EN) A fluid control device includes a filtration component, which has a porous filtration medium. The filtration medium contains a shape memory thermoset material foamed with a polymeric microsphere and a gas-producing chemical foaming agent. The porous filtration medium is configured to be compacted from an initial shape to a compacted shape, deployed in the borehole, and subsequently expanded to conform to a surface of the borehole.
(FR) La présente invention porte sur un dispositif de commande de fluide comprenant un composant de filtration qui a un milieu de filtration poreux. Le milieu de filtration contient un matériau thermodurcissable à mémoire de forme moussé avec une microsphère polymérique et un agent moussant chimique produisant du gaz. Le milieu de filtration poreux est configuré de façon à être compacté d'une forme initiale à une forme compactée, déployé dans le trou de forage, puis dilaté pour se conformer à une surface du trou de forage.
