Abstract: A downhole coupling mechanism for use in downhole tools that find application in wells exploited by a hydraulic refracturing process. The downhole coupling mechanism connects first and second tubular sections via a tensile load arrangement of wires located in complimentary grooves, a torque arrangement of interlocking lugs and notches on opposite ends, and a seal arrangement. The downhole coupling mechanism provides a thin walled coupling where a screw-threaded connection could not achieve the required tensile load, torque and sealing properties needed. Embodiments of a thin walled anchor and packer including the downhole coupling mechanism are described.

Abstract: A frac plug with lower slips and a lower cone. In embodiments, a lower cone ramp angle is greater than or equal to a cone bevel angle and a slip inner cut angle. This geometry enables the fins of the cone to not interact with the lower slips, which may not break the lower slips as the lower slips move over the cone. Instead, the lower slips may break due to stresses caused by the tendency of the lower slips to expand as they lower slips interact with the ramp of the lower cone.
