  • Patent number: 11072695
    Abstract: A rubber composition for a studless tire according to an embodiment includes a rubber component containing a natural rubber and a polybutadiene rubber; oil-absorbent polymer particles having a glass transition temperature of ?70 to ?20° C., formed from a polymer whose molecular weight distribution is less than 3.0, and having an oil absorption of 100 to 1,500 ml/100 g; and an oil. The content of the oil-absorbent polymer particles is 0.5 to 25 parts by mass per 100 parts by mass of the rubber component. As a result, on-ice performance and rolling resistance performance can be improved.

    Abstract: A pre-set inhibiting extrusion limiter has a segmented anti-extrusion ring with a plurality of anti-extrusion ring segments supported by a stepped cone frustum. Each ring segment is retained in a run-in condition by a compression spring retained by a retainer ring held in a retainer ring groove in the respective anti-extrusion ring segments. A push ring moves the respective anti-extrusion ring segments from the run-in condition to a packer-set condition in which the anti-extrusion ring segments abut a cone frustum step of the stepped cone frustum.

  • Patent number: 10961808
    Abstract: A resettable elastomeric packer element of a packer, compressed for sealing in a wellbore, is released from sealing engagement in the wellbore by applying tension to an end of the packer element. The elastomeric packer element stretches and releases from the wellbore forming an annular passageway between the packer element and the wellbore. In the absence of a pressure equalization valve or flow passages through the packer, the annular passageway equalizes pressure differentials across the packer element allowing a tool, in which the packer is incorporated, to be moved in the wellbore with little or no damage to the packer element and further, allows debris to flow from above the packer to below the packer.

  • Patent number: 10822912
    Abstract: An extrusion ring has a base from which multiple segmented rows of rings integrally extend. Gaps in one row are offset from the adjacent row to cover any gaps. The rows gain strength from a common base that also prevents relative rotation among the rows. The overlapping rings are additively manufactured with breakable restraints in some or all the gaps that fail during the setting such as in shear. Faster running in rates can be realized as each ring row has hoop strength due to the ties in the gap or gaps that are incorporated into the additive manufacturing process to make the assembly. Residual stresses in each ring from the additive manufacturing process are resisted from the ties in the gaps. Ties between overlapping rows are also contemplated.

  • Patent number: 10704355
    Abstract: A sealing element is flanked by wedge-shaped extrusion ring assemblies. The extrusion rings are continuous for 360 degrees and are slotted from the outside dimension and alternatively from the inside dimension to allow the diameter to increase to the surround tubular or open hole. The extrusion rings climb a ramp on an adjacent pedestal ring on the way out to the borehole wall. Depending on the dimension of the gap to be spanned the extrusion ring slides a variable distance up the pedestal ring ramp. An optional anchor ring is initially forced up an opposite ramp of the pedestal ring. If the sealing gap is short the anchor ring can be eliminated. For larger gaps the anchor ring moves out far enough toward the borehole wall to contact the extrusion ring located on an opposing ramp of the pedestal ring so that reaction forces are directed to keep the anchor ring wedged in position for support of the extrusion ring assembly.

The sealing element is configured to expand radially-outward from a contracted state to an expanded state. The cone may be positioned around the mandrel and proximate to the sealing element. The plurality of fingers may be positioned at least partially around the mandrel. The fingers may be axially-aligned with at least a portion of the sealing element. The fingers are coupled to a base and configured to break away from the base at a weak point when the sealing element expands into the expanded state. The slip may be positioned around the mandrel and proximate to the cone. The slip may include a tapered inner surface configured to slide along a tapered outer surface of the cone.

  • Patent number: 9605510
    Abstract: A wellbore cementing tool configured for placement in a wellbore or in a drill string, and method of using same. The tool comprises a body having upper and lower members connected by a shear component. A rod is connected to the upper member, and the tool can be lowered with the rod into the wellbore or drill string to a desired depth. At the desired depth, locking means are deployed to lock the tool in position, the tool is sealed, and cement can be injected through the tool to the annulus of the outer casing. In some embodiments the tool is locked using a pushing motion that extends locking members outwardly from the tool to engage the wellbore walls or the inner surfaces of the drill string. Once cementing is completed, the rod is pulled from surface thereby causing the shear component to rupture and the upper and lower members to disconnect, and the upper member can be drawn to surface leaving the rest of the tool downhole.

  • Patent number: 9464500
    Abstract: Rapid swelling and un-swelling materials provide for rapid actuation of well tools. A well tool can include a swellable material, with the swellable material comprising a swellable glass material. A method of actuating a well tool in a subterranean well can include contacting a swellable material of the well tool with an activating fluid in the well, thereby causing the swellable material to swell. The well tool rapidly actuates in response to contacting the swellable material with the activating fluid.

  • Patent number: 8991485
    Abstract: A slip assembly adapted to be used with a downhole tool which comprises metal slip inserts attached to a slip carrier made of a non-metallic material, such as composite material. As such, the non-metallic slip carrier can eliminate 60-70% or more of the metal used in conventional slip assemblies. Through use of the disclosed slip assembly, downhole tools may be set, while also reducing the metallic material used therein and, thus, greatly reducing the drill out time.
