  • Mechanically actuated casing drive system tool
    Patent number: 8739888
    Abstract: A casing gripper is stabbed into a casing and energized by a top drive, gripping the casing. The casing gripper includes a load bearing mandrel that has external threads. The casing gripper also includes a nut threaded over the external threads, and a wrench having a portion of the upper end of the load bearing mandrel inserted into an opening of the wrench. The wrench is configured to prevent rotation of the nut but allow axial movement while the op drive rotates the mandrel. The casing gripper includes a grapple coupled to the nut and extending along a portion of the lower end of the load bearing mandrel. The grapple moves axially with the nut an is configured to radially expand and engage a casing member.
