  • Patent number: 10794140
    Abstract: A system including a wellhead hanger, such as a casing hanger, and a running tool with a stopping protrusion that reduces the likelihood over-torqueing of threads coupling the running tool to the wellhead hanger and that reduces the break-out torque for disengaging the running tool and wellhead hanger from each other upon the completion of casing string cementing. Limiting the thread-per-inch count of the hanger and running tools, respectively, to the range of two threads-per-inch to four threads-per-inch also lowers the break-out torque between the hanger and running tool.

  • Publication number: 20200289728
    Abstract: Provided is a loading tray assembly for housing a lyophilization container and a related system and method. The loading tray assembly includes a chassis including a contact void configured to facilitate direct contact between the attached lyophilization container and a lyophilizer shelf. The method includes securing a multi-part lyophilization container including a peelable seal on a lyophilization loading tray assembly, inputting a liquid into a non-breathable section of the lyophilization container, loading the tray assembly into a lyophilizer, freezing the liquid, applying heat energy and a vacuum, the vacuum causing an opening of the peelable seal and occluding the lyophilization container to isolate the frozen liquid.

  • Patent number: 10738556
    Abstract: A fluid-driven adapter for a mineral extraction system is provided. The adapter includes a sleeve (e.g., annular piston) that engages a mandrel disposed in a wellhead component and moves in an axial direction in response to fluid pressure. The adapter moves the mandrel between a first position and a second position to open or close passages in the wellhead component. The adapter includes a lock ring that moves in response to fluid pressure and that locks the adapter to a wellhead assembly to prevent axial movement of the adapter. Methods of operation are also provided.
