Tubing hanger apparatus
US 3830295 A
Abstract
A tubing hanger is run into the well on a setting tool and supports a dual tubing string when the hanger is set in the well casing. The setting tool is removed and a dual, full opening shutoff valve assembly is run into the well and seats in the tubing hanger. Control fluid pressure supplied from the top of the well holds the shutoff valves open. The dual shutoff valve is retrievable, and the tubing hanger is then retrievable by a retrieving tool.
