摘要： A blowout preventer and seal assembly for sealing a wellbore penetrating a subsurface formation is provided. The blowout preventer includes a housing having a flow path therethrough in fluid communication with the wellbore and a sealing assembly positionable in the housing about the flow path. The sealing assembly includes a piston slidably positionable in the housing and a packer element. The packer element includes a plurality of fingers and a packer seal. The fingers include a housing portion and a piston portion. The housing portion is slidably movable along the housing and the piston portion is slidingly movable along the piston. The fingers are engageable by the piston and movable to a sealed position about the flow path whereby the packer seal is energized to form a seal about the blowout preventer.

摘要： A system for producing mechanical energy. In some embodiments, the system includes a first source providing a first fluid, a fluid pressurization device, a second source supplying a second fluid, a first motor, and a second motor. The fluid pressurization device draws in the first fluid from the first source and increases the pressure of the first fluid. The first motor is driven by the second fluid, the second fluid decreasing in pressure and the first motor powering the fluid pressurization device as the second fluid passes through the first motor. The second motor receives a mixture of the first fluid from the first motor and the second fluid from the fluid pressurization device, whereby the second motor produces the mechanical energy.

摘要： The disclosure provides devices and methods for controlling the actuation rates of SPM valves by bi-directionally controlling the fluid which actuates the valve or by maintaining enclosed volumes which communicate with each other through predetermined restrictions as the valve actuates. These enclosed volumes can be completely isolated, depth compensated, share fluid with the pilot actuating fluid, or utilize the main system fluid. The restrictions can be modified to increase or decrease the actuation rates of the SPM valve. The disclosure also provides control over the main system fluid passage opening and closing positions as well as how rapidly the flow passage areas increase or decrease while opening or closing the valve.

摘要： The present disclosure relates to a monitor for a blowout preventer of a wellbore. The blowout preventer includes a housing, rams, and an actuator comprising a cylinder with a piston. The piston is operatively connectable with the ram and movable therewith. The monitor includes a monitor base operatively connectable to the cylinder (the monitor base having an interior side inside the cylinder and an exterior side outside the cylinder), an interior plate positionable inside the cylinder about the interior side of the base (the interior plate operatively connectable to the piston and movable therewith), an exterior plate positionable outside the cylinder about the exterior surface of the monitor base (the exterior plate coupled by magnets to the interior plate and rotatable therewith), and a trigger sensor operatively connectable about the monitor base and the exterior plate to detect rotation thereof whereby a position of the ram may be determined.

摘要： A clam assembly for connecting adjacent tubulars positionable in a wellbore of a wellsite for passing fluid therethrough comprises at least one drive mechanism. The clam assembly includes a plurality of segments selectively movable between an open position to receive the adjacent tubulars and a closed position positionable around the adjacent tubulars. The segments are disposable about a periphery of the adjacent tubulars. The drive mechanism is carried by the segments, and include a driver to drive a connector through the adjacent tubulars. The driver is movable between a retracted and an extended position to drive the connector whereby a connection is formed between the adjacent tubulars.
