Title (EN) DEGRADABLE BALLS FOR USE IN SUBTERRANEAN APPLICATIONS
(FR) BILLES DÉGRADABLES POUR UTILISATION DANS DES APPLICATIONS SOUTERRAINES
Abstract: front page image
(EN)Degradable balls for downhole use may include an incompliant degradable polymer and a compliant filler material, the incompliant degradable polymer having an elastic modulus of about 2 GPa or greater, and the compliant filler material having an elastic modulus of less than about 2 GPa. Such degradable balls may be useful in sealing segments of a wellbore and actuating wellbore tools.
(FR)La présente invention concerne des billes dégradables d'utilisation en fond de trou pouvant comprendre un polymère dégradable non souple et un matériau de charge souple, le polymère dégradable non souple ayant un module d'élasticité d'environ 2 GPa, ou plus, et la matière de charge souple ayant un module d'élasticité inférieur à environ 2 GPa. Ces billes dégradables peuvent être utiles lors du scellement de segments d'un puits de forage et de la commande d'outils de puits de forage.
