Abstract
A thru-tubing completion system includes a sub-surface completion unit (SCU) configured to pass through a production tubing disposed in a wellbore in at least an open holed portion of the wellbore and perform completion operations in the target zone. The SCU includes an expandable liner; and one or more SCU anchoring seals configured to be positioned in an un-deployed position and a deployed position. The un-deployed position of the one or more SCU anchoring seals enables the SCU to pass through the production tubing, and the deployed position of the one or more SCU anchoring seals provides a seal against a wall of the open holed portion of the wellbore to provide zonal isolation between regions in the wellbore. The one or more SCU anchoring seals includes a chemically active expandable metal configured to expand in the deployed position to provide the seal against the wall of the open holed portion of the wellbore.
