Title: ENERGY TRANSFER MECHANISM FOR WELLBORE JUNCTION ASSEMBLY
Abstract:
A unitary multilateral junction for deployment in a wellbore, wherein the multilateral junction permits electrical power and communications signals to be established in both a lateral wellbore and a main wellbore utilizing. The unitary junction assembly generally includes a conduit with a first upper aperture, a first lower aperture and a second lower aperture where the first lower aperture is defined at the distal end of a primary passageway extending from a conduit junction and a second lower aperture defined at the distal end of a lateral passageway extending from the conduit junction. A lower wireless energy transfer mechanism is positioned along at least one of the passageways between the distal end of the passageway and the junction. The lower wireless energy transfer mechanism is in wired communication an upper energy transfer mechanism permitting electrical communication to be established across the intersection of wellbore branches utilizing the unitary junction.
