Abstract
A tool is employed with a subsea wellhead assembly for preventing the collapse of a wear bushing located in a drill-through tubular member due to external test forces being applied to it. The tool has a connector that connects to the drill-through tubular member. A stem extends downward from the connector and has a reacting member at its lower end. The reacting member engages an inner diameter of the wear bushing to resist inwardly directed forces due to fluid pressure on the exterior of the wear bushing. The tool can be incorporated with a running tool or with a blowout preventer isolation test tool.
