Abstract: A lateral wellbore completion apparatus may include a flow-through deflector having a deflector face and a junction string that includes a junction block cooperative to mate with the deflector face, a downhole device, and an inductive coupler electrically connected to the downhole device. A method may include anchoring the deflector in a main bore, making-up at the drilling surface a junction string that includes a junction block, a completion string section having a downhole device, and a secondary inductive coupler electrically connected to the downhole device, running the junction string into the main bore, deflecting the completion string section into the lateral bore, and landing the junction block on the deflector face thereby communicatively coupling the secondary and primary inductive couplers.

Abstract: A method and apparatus for landing and orienting a production selective landing tool (PSLT) within a well casing. The well casing is provided with one or more indexing casing coupling (ICC). The PSLT is included in a completion string. The PSLT has several landing keys and an orientation key. The PSLT is conveyed through the casing and lands in the ICC. The PSLT has integrated control lines for intelligent completion. The PSLT has lugs coupled to a mandrel and control lines. The lugs, the mandrel and the control lines are shifted relative to the body of the PSLT. The control lines are in a slot of the body. The PSLT is locked in the ICC when the mandrel is shifted. The PSLT can be removed from the ICC via pulling the completion string uphole.
