Abstract: A modular tool body having upper and lower sections, a pair of longitudinal members define a central open region, the longitudinal members joined at one end having a lifting feature formed therein configured to accept a manipulator. The lifting feature is positioned such that when the modular tool body and a rig tool connected thereto are lifted by the manipulator, they are easily moved over, aligned with, and connected with a working drillpipe or other rig tool while minimizing possibility of the manipulator slipping off. The lower section includes a threaded end mating with a mating end of a rig tool, a central longitudinal bore, and an upper end formed to accept the lower ends of the longitudinal members of the upper section. Elongate slots in each longitudinal member define one or more manipulating handles. A pair of generally horizontal hand holds may be formed in each longitudinal member.

Abstract: Inside blowout preventer release tool having an upper section and a tubular lower section. The upper section includes a pair of longitudinal members defining a central open region, and a formed lifting feature accepting a manipulator. The lifting feature is positioned such that when the release tool body and an inside blowout preventer connected thereto are lifted by the rig hoist they are easily moved over, aligned with, and connected with a working drillpipe while minimizing possibility of slipping off cables or chains. The lower section includes a threaded end mating with a mating end of an inside blowout preventer, a central longitudinal bore to accept a length-adjustable release rod, and an upper end formed to mate with the upper section. Slots in each longitudinal member may define one or more manipulating handles for a rig worker, machine, or tool, or a pair of generally horizontal hand holds are provided.

Abstract: Inside blowout preventer release tool body having a one-piece planar upper section and a one-piece tubular lower section. In one embodiment, the upper section includes a pair of longitudinal members defining a central open region, the longitudinal members joined at one end having a formed lifting feature configured to accept a manipulator cable or chain. The lifting feature is positioned such that when the release tool body and an inside blowout preventer connected thereto are lifted by the rig hoist using cables, chains, and the like, they are easily moved over, aligned with, and connected with a working drillpipe while minimizing possibility of slipping off the cables or chains. The lower section includes a threaded end mating with a mating end of an inside blowout preventer, a central longitudinal bore to accept a release rod, and an upper end formed to accept the lower ends of the longitudinal members of the upper section.
