A method and apparatus especially adapted for use with an injection well in which a valve controlled H-member interconnects the two tubings of a two tubing installation and landing nipples are attached to the lower legs of the H-member to receive expendable fluid control means, such as standing valves, in which pressure applied to one tubing to create a pressure differential will move the valve controlling the interconnection between the H-members to open position to permit TFL operations to be carried out in the well and thereafter pressure exerted on a ball supported on the valve member of the control valve for the H-member closes the control valve, and the ball passes through the control valve. The fluid control members in the landing nipples may be ejected either before or after closing of the valve in the H-member.The standing valve shear pins may be sheared without releasing the valves from their supporting shoulders. When pressure approaches equalization the valves will pass through the supporting shoulders.
