Abstract

See full text

The invention presents a method for plugging and abandoning spent wells. An expandable liner hanger having sealing elements positioned thereon, is run-in and expanded, creating at least one seal against fluid migration. A redundant seal is created using a swellable annular sealing device, such as a swell packer. The swell packer and liner hanger are run-in and expanded. A bottom valve is closed and the expansion and running tools released from the liner hanger. After pulling out of the running tool, the wellbore is cemented creating an effective plug.
