Abstract
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.
Claims23
A downhole completion system, comprising:
- a sealing structure configured to be expanded from a contracted configuration to 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 overlap at least one of the one or more perforations when the sealing structure is in the expanded configuration, the filter device being configured to screen fluids passing through the at least one of the one or more perforations.
A method of completing an open hole section of a wellbore, comprising:
- conveying a sealing structure in a contracted configuration to the open hole section, the sealing structure having one or more perforations defined therein and a filter device coupled to the sealing structure so as to overlap at least one of the one or more perforations;
- radially expanding the sealing structure to an expanded configuration with a deployment device when the sealing structure is arranged in the open hole section, the filter device being expandable with the sealing structure;
- and
- screening fluids passing through the at least one of the one or more perforations with the filter device.
