Patent ID: 8291987

Claim:
A running tool for setting and testing an annular seal having an energizing ring in the annulus between an inner wellhead member and an outer wellhead member of a well, the running tool comprising: an elongated stem having an axial passage; a body surrounding and connected to the stem such that rotation of the stem causes the stem to translate axially relative to the body, the stem extending axially through the body; an engagement element, carried by the body and adapted to be engaged with an inner wellhead member, the axial movement of the stem relative to the body causing the stem to engage the engagement element and move the engagement element into engagement with the inner wellhead member to releasably secure the running tool to the inner wellhead member; and a piston, substantially surrounding portions of the stem and the body and downwardly moveable relative to the stem to thereby drive the energizing ring and set the annular seal.
