  • Expandable connection with metal-to-metal seal
    Patent number: 11053748
    Abstract: An expandable connection is configured such that a metal-to-metal seal is created upon expansion, even under different expansion ratios. The creation of the metal-to-metal seal can rely on a spring-back effect after expansion. A high pressure rating of the metal-to-metal seal that is created can be achieved with an oversized box face thickness. The expandable connection can also be configured to achieve a high tensile efficiency.
    Type: Grant

  • Hydraulically actuated safety sub
    Patent number: 10858894
    Abstract: A safety joint having threads with a first handedness, for example right-handed threads, to connect the safety joint to an upper drill pipe portion and a lower drill pipe portion. The safety joint includes a releasable threaded connection having a second handedness inverse of the first handedness. The safety joint also includes a hydraulically actuated piston sleeve that locks rotation across the releasable threaded connection. Disconnecting the upper drill pipe portion from the lower drill pipe portion is achieved by moving the piston sleeve to a position wherein the piston sleeve does not transmit rotation across the releasable threaded connection, and rotating the upper drill pipe portion in the first handedness direction to unscrew the releasable threaded connection.
