  • Patent number: 12104457
    Abstract: A linear electromechanical actuator with a failsafe design may be used with a downhole flow control system. In one example, a subsurface safety valve for controlling flow of production fluids includes a valve closure element moveable between an open position and a closed position in response to a linear movement of an actuating member. A biasing member biases the valve closure element to the closed position. A power section with an electrically-powered motor drives a rotation. A drive section coupled to the power section converts the rotation of the motor to the linear movement of the actuating member to at least open the subsurface safety valve. A clutch selectively decouples the power section from the drive section in response to a power loss.

  • Patent number: 12050709
    Abstract: Systems, methods and computer program products for controlling access to an organization's data in a multitenant environment are provided. An organization hierarchy is defined at a multitenant platform, the organization hierarchy comprising an organization and a plurality of sites owned by the organization, each of the plurality of sites representing a data isolation boundary for the organization's data. The sites are associated with subscriptions to applications of the multitenant platform. The organization can designate user partitions within the sites, each user partition designating a corresponding set of site users and a corresponding authentication service. The multitenant platform enables access to each subscription of a site only if a site user is authenticated by the authentication service designated in the user partition corresponding to the site user.

  • Publication number: 20240218908
    Abstract: Disclosed herein are systems and methods including an electromechanical brake used downhole to impart dynamic or static braking capabilities while absorbing or otherwise reducing shock loads. The electromechanical brake may be used for a downhole electromechanical linear actuator to control a valve for the production of subterranean fluid. In some examples, it may be desirable for an electromechanical linear actuator to maintain a retracted position during certain safety and/or maintenance operations. The electromechanical brake includes a brake housing, a first armature rotatably disposed in the brake housing, a second armature rotatably disposed in the brake housing for rotation by a motor, an electrical coil energizable to urge the second armature into axial engagement with the first armature, and a rotational spring for biasing the first armature to a neutral rotational position relative to the brake housing while allowing a limited rotation of the first armature relative to the brake housing.

  • Patent number: 12024980
    Abstract: A mechanical clutch allows for transfer of torque downhole that may avoid the need for a hydraulic electrical coil-driven piston. In one or more examples, an anti-rotation guide for a downhole clutch includes a guide track and a follower moveable along the guide track for guiding relative movement between an upper armature and a lower armature. The guide track includes an axially-extending portion terminating in a circumferential loop. The axially extending portion guides the upper armature into axial engagement with the lower armature in response to rotation of the input shaft. The circumferential loop thereafter allows rotation of the upper and lower armatures together in response to further rotation of the input shaft.

  • Patent number: 11891866
    Abstract: An actuator of a downhole tool used in oil and gas exploration and production operations is operable to actuate a first implement in a first direction. A biasing device of the downhole tool is operable to actuate the first implement in a second direction, opposite the first direction. A dampener of the downhole tool is operable to slow an actuation speed of the first implement in the first direction, the second direction, or both. Actuating the first implement in the first direction also actuates a second implement of a flow control device (“FCD”) of the downhole tool, to which the first implement is connected, in the first direction, placing the FCD in a first (e.g., open) configuration. Actuating the first implement in the second direction also actuates the second implement of the FCD in the second direction, placing the FCD in a second (e.g., closed) configuration.
