ABSTRACT:
A wellhead assembly is disclosed which accepts a downhole tool run on a wireline within an injection bore in which a central wellhead member has an injection port in communication with the injection bore upstream of an isolation valve within the injection bore. A stinger in the injection bore is movable between an extended position and a retracted position. The extended position of the stinger protects the wireline and the retracted position permits the downhole tool to be withdrawn upstream of the isolation valve.
