Title (EN) DEGRADABLE CASING JOINTS FOR USE IN SUBTERRANEAN FORMATION OPERATIONS
(FR) ACCOUPLEMENTS DE TUBAGE DÉGRADABLES DESTINÉS À ÊTRE UTILISÉS DANS DES OPÉRATIONS EN FORMATION SOUTERRAINE
Abstract:
(EN) A casing joint and systems and methods related thereto. The casing joint comprises a tubular body, a window formed through a sidewall of the tubular body, and a degradable material secured to the tubular body to occlude the window. The degradable material has a degradation rate of greater than 0.0095 milligrams per square centimeters (mg/cm2) at 93.3C when exposed to a 15% potassium chloride solution.
(FR) L'invention concerne un accouplement de tubage et des systèmes et procédés s'y rapportant. L'accouplement de tubage comprend un corps tubulaire, une fenêtre formée dans une paroi latérale du corps tubulaire et un matériau dégradable bien fixé au corps tubulaire pour fermer la fenêtre. Le matériau dégradable a une vitesse de dégradation supérieure à 0,0095 milligramme par centimètre carré (mg/cm2) à 93,3 °C lorsqu'il est exposé à une solution de chlorure de potassium à 15 %.
