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.

Abstract: A technique facilitates improving a completion architecture for a multilateral intelligent well completion (IWC). Effectively, a new and enhanced completion design and deployment approach is provided for multilateral IWCs. According to an embodiment, lower completion equipment is initially deployed downhole into a lower lateral borehole and lower section of a primary borehole. An intermediate completion may then be run downhole and into engagement with the lower completion equipment. Subsequently, an upper lateral borehole (or boreholes) may be drilled and completed. After drilling and completing the one or more upper lateral boreholes, an upper completion is deployed downhole and coupled with the intermediate completion in a manner which enables signal communication with downhole sections of the well.

Abstract: A dual tubing locating adapter (“DLTA”) for use with a mule shoe. The DLTA may include a housing, a primary tubing string, a lateral tubing string, and a retention mechanism. The primary tubing string may be positioned at least partially within the DLTA. The lateral tubing string may be positioned at least partially within the DLTA and retained within the DLTA via a shear mechanism. The retention mechanism may be operable to retain the lateral tubing string within the DLTA as the DLTA is landed on the mule shoe.
