Title (EN) CASING EXIT JOINT WITH GUIDING PROFILES AND METHODS FOR USE
(FR) JOINT DE SORTIE DE TUBAGE POURVU DE PROFILÉS DE GUIDAGE ET PROCÉDÉS D'UTILISATION
Abstract:
(EN) A casing exit joint with guiding profiles and methods for use are provided. In one embodiment, a casing exit joint comprises: a substantially tubular casing joint comprising an inner surface and an outer surface, wherein at least a circumferential portion of the inner surface comprises a plurality of axial inner grooves. In certain embodiments, at least a circumferential portion of the outer surface may comprise a plurality of axial outer grooves. The casing exit joint may be disposed in a wellbore penetrating at least a portion of a subterranean formation, and a cutting tool may cut a window through at least a portion of the casing exit joint. In certain embodiments, the axial inner grooves and/or outer grooves may reduce the amount of milling debris, prevent lateral displacement of the cutting tool, and/or eliminate the need to pre-orient the casing exit joint to achieve the desired exit window.
(FR) L'invention concerne un joint de sortie de tubage pourvu de profilés de guidage et des procédés d'utilisation. Dans un mode de réalisation, un joint de sortie de tubage comprend : un joint de tubage sensiblement tubulaire comprenant une surface interne et une surface externe. Au moins une partie circonférentielle de la surface interne comprend une pluralité de rainures internes axiales. Dans certains modes de réalisation, au moins une partie circonférentielle de la surface externe peut comprendre une pluralité de rainures externes axiales. Le joint de sortie de tubage peut être disposé dans un puits de forage pénétrant dans au moins une partie d'une formation souterraine et un outil de coupe peut couper une fenêtre à travers au moins une partie du joint de sortie de tubage. Dans certains modes de réalisation, les rainures internes axiales et/ou les rainures externes peuvent réduire la quantité de débris de broyage, empêcher un déplacement latéral de l'outil de coupe et/ou éliminer le besoin de pré-orienter le joint de sortie de tubage afin d'obtenir la fenêtre de sortie souhaitée.
