Abstract

The dual string hanger assembly includes an insert and an adaptor. The insert is installed within the inner diameter of the tubing head and the adaptor is coupled over the top of the tubing head. The insert therefore becomes sealed within the interior space between the tubing head and the adaptor. In use, the production string is supported in a tubing hanger profile built into the adaptor above the existing tubing head. The auxiliary line is supported in a second, smaller diameter hanger profile that is on the insert, which is installed within the tubing head. The assembly may include a hanging apparatus, such as slips, to secure the auxiliary line in the hanger profile of the insert.
