ABSTRACT:
In the area of oilfield wellhead equipment and well servicing, specifically the operations associated with the prevention of fluids and gases from escaping from the well when valves and associated equipment which normally control the flow of these fluids and gases have been removed for repair or for any other reason, the installation of and removal of a plug in the top of the tubing hanger is a common and necessary operation. This plug is commonly called a back-pressure plug and is a standard throughout the industry. A tool is proposed for installing and removing this plug while the well is under pressure, which tool will indicate that the plug is properly in place and will also overcome the operational problems associated with existing tools and the overall height associated with existing tools.
