Abstract: The frac plug device is a wedge type or ramp type frac plug that can seal at a setting position in a large diameter portion of the borehole. The thickness, taper angle, and dimensions of components for passing through the narrowest portion of the borehole during deployment no longer limit the radial expansion. The frac plug device includes a core cone, a segmented cone, a slip device, a segmented cap member, and a core cap member. A simplified setting action sets the high expansion of the slip device by the core cone and the segmented cone. The segmented cone and the segmented cap member increase expansion of the slip device, and the segmented cap member and the core cap member lock the slip device around the core cone in the final expansion configuration at the maximum radial expansion for large diameter portions of the borehole.

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.

Abstract: A downhole tool includes a cone, a slips assembly positioned at least partially around the cone, and a shoe configured to press against the slips assembly. The shoe is configured to engage a setting assembly, so as to apply an axial force to the slips assembly that moves the slips assembly relative to the cone and drives the slips assembly radially outwards. The shoe is made at least partially from a dissolvable material configured to dissolve in a fluid in a well, and the cone, the slips assembly, or both are at least partially made from a second material that is configured not to dissolve in the fluid in the well.

Abstract: A ramp type frac plug device of the present invention is a simplified, short and compact frac plug device to both maintain seal to the borehole wall and prevent premature release from the borehole. The frac plug device includes a cone, an anchor assembly, a cap member, a slip device, and a sealing member. In a set configuration, the frac plug device has both the friction fit engagement of the cone and the slip device and a single direction rachet locked engagement of an anchor ring with a threaded ring portion and an anchor mandrel with an exterior threaded mandrel portion of the anchor assembly. The ratchet lock engagement between the anchor ring and the anchor mandrel prevents backward movement of the cone away from the anchor mandrel so that the cap member engaged with the anchor mandrel locks the slip device in position on the cone.

Abstract: A safety plug for use in a bore hole comprising a bore wall. The safety plug comprises a body having a leading end and a trailing end, and at least one flared portion. An anchoring element extends at least partially around an associated flared portion. Axially displacement of anchoring element relative to its associated flared portion causes the anchoring element to bear against the flared portion and transitions the anchoring element between an unexpanded condition and an expanded condition. A nose, comprising conical elements, extends longitudinally from the leading end of body. The nose is longitudinally compressible.
