Abstract
A system involving a lower tubing mounted safety valve having one or two control lines further contains a landing nipple above for a wireline insert valve. One line that serves the lower safety valve is tied to a connection on the landing nipple for the insert valve. When the lower safety valve malfunctions the landing nipple wall is penetrated to get communication to the line coming from the lower safety valve so that such line can serve as a balance line for the insert valve. The other line from the surface to the other connection on the landing nipple serves as the operating line for the insert valve. Making one line serve a dual purpose eliminates one control line from the surface.
