Abstract
An apparatus and method for completing a junction between a primary and secondary wellbore. A deflector is located in the primary wellbore adjacent to the wellbore junction. The apparatus comprises a conduit comprising: an upper section; a lower section comprising a primary leg for engaging a seat of the deflector and a secondary leg for insertion in the secondary wellbore; and a deformable conduit junction located between the upper and lower sections whereby the conduit is separated into the legs; such that when the apparatus is lowered in the primary wellbore, the secondary leg is deflected into the secondary wellbore by the deflector such that the conduit junction becomes deformed, and the primary leg then engages the seat.
