Abstract

A tubing hanger and a method for axially displacing tubing string in a cased well bore without removing the wellhead from the well are described. The tubing hanger consists of a primary tubing hanger component engageable with the wellhead and a secondary tubing hanger component removably received in the cavity of the primary tubing hanger component. When downhole operations require axial displacement of the tubing string, the secondary tubing hanger component is disengaged from the primary tubing hanger component and stroked up through the wellhead to permit tubing joints to be added or removed. Such axial displacement of the tubing string facilitates downhole operations such as the repositioning of a zone isolating tool, the logging of a production zone, the removal of debris such as sand from a sand trap, selective stimulation of a production zone, and other localized downhole operations which require or are facilitated by tubing string manipulation. The advantage is the ability of axially displace the tubing string without removing the wellhead which saves time and significantly reduces costs.
