Abstract

A technique for facilitating the use of a variety of completion elements in a wellbore environment. The technique utilizes an insertion guide disposed within an open-hole section of a wellbore. The insertion guide may be radially expanded towards the surrounding formation to remove excess annular space. The expansion of the insertion guide further allows the use of a completion element having a greater diameter than would otherwise be afforded.
