Enhanced expandable tubing run through production tubing and into open hole

摘要

Disclosed is a downhole completion assembly for sealing and supporting an open hole section of a wellbore and filtering fluids passing therethrough. One system includes a sealing structure arranged within the open hole section and being movable between a contracted configuration and an expanded configuration, the sealing structure having one or more perforations defined therein, and a filter device arranged about the sealing structure so as to radially overlap the one or more perforations, the filter device being configured to screen fluids passing through the one or more perforations.
