Abstract
A sealed wellbore junction is conveniently and efficiently created in a subterranean well. In one described embodiment, a first assembly including a deflection device is positioned in the well adjacent a junction of parent and lateral wellbores. A second assembly is then sealingly engaged with the first assembly, thereby sealing the junction, and providing fluid communication between the lateral wellbore and upper and lower portions of the parent wellbore. Sealing engagement between the first and second assemblies may be provided by a variety of sealing members, or by metal-to-metal contact between the assemblies.
