  • Publication number: 20240035347
    Abstract: A release tool for connecting a workstring to a toolstring. The release tool will be used for contingency if the toolstring gets stuck downhole and hopefully rarely would be actuated. In the present disclosure, the release tool is not broken or destroyed, but is simply disconnected into two parts using the propellent of a low explosive combustion element. This element produces gasses that drive the disconnecting process. The gasses are directed to press a tubular piston to translate from a first position where a wedging portion of the tubular piston is inside a lock ring bracing the lock ring in a locking configuration to a second position where the wedging portion is out of contact with the lock ring. The lock ring is then able to slip free from one or more locking grooves releasing the upper portion of the release tool from the lower.

  • Publication number: 20240026748
    Abstract: A frac plug is disclosed that is used for isolating a lower portion of a wellbore from an upper portion to enable a fracking process on newly created perforations in casing or liner pipe where the frac plug is particularly designed rapid drill out after all the fracking operations have been completed. The frac plug includes arrangements for holding the polymer or rubber element from rotation as the plug is being drilled. One arrangement includes pins that lock the polymer element to the bottom cone. In another, the polymer element is simply bonded by adhesive to the faceted cone. The facets on the cone prevent the cone from rotating in the wellbore by being pressed against the flat bottom slip segments that remain locked to the casing or liner pipe.
