  • Patent number: 10745990
    Abstract: The present disclosure relates to a system that includes a shearing ram configured to mount in a blowout preventer. The shearing ram includes a body portion that may move along an axis of movement. The shearing ram also includes a sealing member disposed in a first surface of the body portion. The sealing member is biased away from the first surface in a crosswise direction relative to the axis of movement, such that the sealing member may engage a second surface of a second shearing ram when the first shearing ram and the second shearing ram overlap with one another with respect to the axis of movement.

  • Patent number: 10590728
    Abstract: A packer assembly for an annular blowout preventer includes an annular packer and a plurality of inserts arranged circumferentially about the annular packer. The plurality of inserts are curved along an axial axis of the packer assembly and are configured to rotate radially inwardly to enable the packer assembly to move from an open position in which the packer assembly enables fluid flow through a central bore to a closed position in which the packer assembly blocks fluid flow through the central bore.

  • Patent number: 9976373
    Abstract: A blowout preventer may be used for shearing an object positioned in a vertical bore extending through the blowout preventer. The blowout preventer includes a shear ram movable towards the tubular, the shear ram including a biasing mechanism for biasing against an interior surface of the blowout preventer body. In this way, the biasing mechanism urges the shear ram into axial engagement with an opposing shear ram movable towards the tubular during shearing operations. The biasing mechanism comprises a biasing member, such as a coiled spring, coned-disc spring, and/or coned-disc washer which urges the biasing mechanism into contact with the inner portion of the blowout preventer body.

  • Publication number: 20170058625
    Abstract: A pipe ram blowout preventer may be used for sealing about an object positioned in a vertical bore extending through the blowout preventer. The blowout preventer includes a pipe ram assembly movable towards the tubular, the pipe ram assembly including a packer assembly comprising an elastomeric body for sealing against the object. The packer assembly includes an upper plate position above the elastomeric body which includes a tab extending from the upper plate. The tab resists extrusion of the elastomeric body in high temperature environments by containing the elastomeric material and forming a metal-to-metal seal about the object positioned in the blowout preventer vertical bore.

  • Publication number: 20170058626
    Abstract: A pipe ram blowout preventer (“BOP”) may be used for sealing about an object positioned in a vertical bore extending through the BOP. The BOP includes a pipe ram assembly movable towards the tubular, the pipe ram assembly including a packer assembly comprising an elastomeric body for sealing against the object. The packer assembly includes a packer insert within the elastomeric body, the packer insert comprising a generally interlaced structure, such as a wire mesh. The packer insert reduces deleterious effects of using a pipe ram assembly in high temperature environments by resisting crumbling of the elastomeric material when it becomes brittle.

  • Patent number: 8727303
    Abstract: A variable bore packer used in a blowout preventer to form a seal against different diameter tubular members for oil and gas drilling operations. The variable bore packer includes a packer member molded of elastomeric material with certain mechanical properties and including an inside curved surface. The packer also includes a plurality of packer inserts molded within the packer member to form an insert array. Additionally, the packer includes a protrusion extending from and bonded to the packer member inside curved surface, the protrusion including increased mechanical properties compared to the packer member. The packer member, the insert array, and the protrusion are molded into a unitary structure and sized to form a seal against the different diameter tubular members upon closure of the blowout preventer. Also, the insert array and the protrusion diminishing extrusion of the elastomeric material between the packer inserts and the tubular members.
