MULTILATERAL INTELLIGENT WELL COMPLETION METHODOLOGY AND SYSTEM

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.
