==Original Abstract Submitted==

An insertion tool assembly includes a lubricator and a tubular adapter. The tubular adapter includes a main body with a central bore therethrough. A top end of the adapter can be attached to the lubricator and the bottom end attached to a crown top of a wellhead. The tubular adapter also includes a kill fluid port disposed through a side-wall of the main body. The insertion tool assembly is configured such that, when the BPV is attached to the distal end of the rod and the bottom end of the tubular adapter is attached to the crown top, the BPV can pass through the tubular adapter and into the wellhead through the crown top as the rod is extended from the lubricator, and a kill fluid injected into the kill fluid port can flow through the crown top into the well.
