Junction assembly, system and method for providing a downhole junction

摘要

The invention is directed at a junction assembly adapted for insertion in a borehole and a system and a method for providing a junction in a borehole. The junction assembly is comprised of a primary conduit and a lateral conduit. The primary conduit has an upper end, a lower end, and defines a primary conduit bore extending through the primary conduit from the upper end to the lower end. The lateral conduit is connected with the primary conduit at a conduit junction located between the upper end of the primary conduit and the lower end of the primary conduit, wherein the lateral conduit extends within the primary conduit bore from the conduit junction towards the upper end of the primary conduit.
