1. A multilateral junction system comprising:
a multilateral junction device including: a first bore leg; a second bore leg; a joint section having a first opening connected to the first bore leg and a second opening connected to the second bore leg; a main body extending from the joint section and including a third opening; a tubular inner window sleeve positioned within the main body, the window sleeve extending from the third opening to the joint section, the window sleeve including a radially directed window, the window including a first portion and a second portion, the first portion enabling fluidic communication between the first and third openings and between the second and third openings, the second portion having a different outer peripheral edge than the first portion, the second portion including an orientation edge surface configured to cooperate with an exterior orientation feature of a downhole tool; and, a tube connected to the third opening, the tube configured to enable an upper completion to be run into a borehole together with the multilateral junction device. |
