  • Patent number: 10329870
    Abstract: A backup ring assembly has a base ring to support the plastically deformed extrusion barrier when the packer sealing element is set. The base ring has a thin walled tapered extending ring out of the base ring and into the direction of the sealing element. The sealing element fills the annular gap volume between an upper taper on the extending ring and the body of the backup ring such that on setting the pressure internally in the seal material helps to apply a force in a direction toward the mandrel and for the full circumference of the mandrel. This force and the flexibility of the extending ring helps push the extending ring toward the mandrel outer surface to close extrusion gaps between the mandrel and the base ring of the backup ring assembly.

  • Patent number: 10077625
    Abstract: A mandrel and a packer outer assembly are formed to create spring compartments on opposed sides of a sealing element. The outer assembly is shear pinned to the mandrel to minimize spring travel during setting. Once set in the normal way the presence of the springs transfers load and sustained loads through the connected tubular string in either direction. A load coming from downhole and acting in an uphole direction first compresses the spring located uphole from the sealing assembly so that the loading goes behind the sealing assembly and into the upper spring and ultimately to the upper slips. The reverse happens when the force is coming from uphole of the sealing assembly and acting in a downhole direction. The springs can be a coil, a stack of Belleville washers, fluid pushed through an orifice, a resilient material or a contained compressible fluid, to name some examples.

  • Patent number: 9995103
    Abstract: A sealing element is flanked by wedge-shaped extrusion ring assemblies. The 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 rings slide part way up the pedestal ring ramp or to the top of the pedestal ring. An anchor ring is initially forced up an opposite ramp of the pedestal ring. If the sealing gap is short the anchor ring touches the borehole wall to act as an anchor for the plug while remaining spaced apart from the extrusion ring assembly. For larger gaps the anchor ring moves out far enough to the borehole wall and in contact with the extrusion ring located on top of the pedestal so that reaction forces are directed to keep the anchor ring wedged in position for support of the extrusion ring assembly.

  • Patent number: 9562410
    Abstract: A slip design has segments that move relatively axially before moving in tandem up a ramp for radial extension. Due to the fact of the relative movement the segments interlock due to their geometric configuration or their surface treatment such that at the conclusion of such relative movement the load carrying thickness is effectively increased. The extended position minimizes radial extension of the slips for a smaller tool drift dimension while still allowing the needed radial extension and actually extending the radial reach of the slip assembly. The segment can have triangular or trapezoidal tapered interfaces that provide bearing areas between slip segments and adjacent spacer segment. Alternatively, the slips segments can have opposing wickers so that after riding up an underlying support member can interact with that member for load transfer. The supporting members can also be secured to an underlying mandrel for further load transfer.

  • Patent number: 9441450
    Abstract: A wellbore cementing tool configured for placement in a drill string, and method of using same. The tool is lowered on a hollow, small-diameter stem into the drill string and contacts the bit, such that the downward pressure on the tool causes a shear pin to shear, resulting in upward movement of an outer sleeve relative to the central body of the tool. The outer sleeve normally holds outwardly biased locking members in a retracted position, but when the outer sleeve is upwardly displaced, slots in the outer sleeve align with the locking members and allow the locking members to extend outwardly through the slots to engage the inner wall of the drill string thereby locking the tool in place. When in position, cement can be injected through the tool and the bit, circulating up the wellbore annulus. The tool does not require rotation to engage the drill string.

    Abstract: A packer for a well. The packer comprises a seal element and seal setting apparatus. The seal setting apparatus is moveable with respect to the seal element in a setting direction to apply a setting force to the seal element to move the seal element from a run-in configuration to a set configuration in which, in use, the seal element forms a contact seal with a conduit wall. In use, the packer is arranged such that, in the set configuration, a pressure differential across the packer, which creates a force in the setting direction, will increase the setting force applied by the seal setting apparatus to the seal element to maintain the seal.
