Abstract

A multilateral completions assembly having selectively isolated lateral legs during hardware installation. The assembly includes a variety of isolation sleeves disposed interior of the main bore casing and adjacent corresponding pre-located windows through the casing. Thus, lateral legs may be sequentially created through the formation at each window in a manner that allows for follow-on isolation. As a result, fluid losses from newly formed legs may be avoided during completions operations. That is, as each leg is formed it may also be isolated in advance of forming of the next leg thereby enhancing the efficiency of completions operations as well as follow-on production.
