  • Piston and gate assembly for kinetic pressure control apparatus ram
    Patent number: 11834922
    Abstract: A ram for a blowout preventer has a pressure chamber having a piston movably disposed therein, and a charge disposed at one end of the pressure chamber. A gate is coupled to the piston on a side opposed to the charge. The gate is arranged to move across a through bore in a housing disposed at an opposed end of the pressure chamber. A coupling between the piston and the gate has sufficient strength to transfer kinetic energy of the gate to the piston.

  • Managed pressure drilling system and method
    Patent number: 11719055
    Abstract: A method for controlling pressure in a well includes pumping fluid into a riser extending between a drilling vessel and a wellhead, pumping fluid out of the riser to the drilling vessel by operating a first jet pump disposed in a conduit extending from the riser to the drilling vessel, wherein a rate of pumping power fluid into a power fluid inlet of the first jet pump is adjusted to maintain a liquid level in the drilling riser at a selected elevation.
