Title (EN) INSTRUMENTED MULTILATERAL WELLBORES AND METHOD OF FORMING SAME
(FR) PUITS DE FORAGE MULTILATÉRAUX INSTRUMENTÉS ET LEUR PROCÉDÉ DE FORMATION
Abstract:
(EN) A method of completing a wellbore system that includes a main wellbore and a lateral wellbore intersecting the main wellbore at a junction is disclosed, wherein in one embodiment the method includes placing a first outer assembly below the junction in the main wellbore and placing a second outer assembly below the junction in the lateral wellbore; placing a first inner assembly in the second outer assembly with a top end thereof below the junction, the top end of the first inner assembly including a first wet connect associated with at least one link in the first inner assembly; and connecting a second wet connect of a string with the first wet connect with a top end of the string having a third wet connect corresponding to the at least one link above the junction in the main wellbore.
(FR) L'invention concerne un procédé de complétion d'un système de puits de forage qui comprend un puits de forage principal et un puits de forage latéral croisant le puits de forage principal au niveau d'une jonction, dans un mode de réalisation, le procédé consistant à placer un premier ensemble externe sous la jonction, dans le puits de forage principal, et à placer un second ensemble externe sous la jonction, dans le puits de forage latéral ; à placer un premier ensemble interne dans le second ensemble externe dont une extrémité supérieure de celui-ci est sous la jonction, l'extrémité supérieure du premier ensemble interne comprenant un premier raccord humide, associé à au moins une liaison dans le premier ensemble interne ; à relier un deuxième raccord humide d'un train de tiges au premier raccord humide, une extrémité supérieure du train de tiges ayant un troisième raccord humide correspondant à la ou aux liaisons au-dessus de la jonction dans le puits de forage principal.
