Abstract: Rotating control device related oilfield pressure control is accomplished by upper (26a) and lower (26b) seal members configured to seal around a tubular (40), a chamber (44) defined between the upper and lower seal members; and wherein fluid enters and/or exits the chamber via some device or structure (60, 70). Such a device or structure could be a relief valve (60), a first accumulator (70), a pressure control valve, an orifice, and/or a void space in a seal member in a location which contacts the tubular.

Abstract: A device and method to control the rate of radial expansion of a compressible sealing element on a packer over the longitudinal length of the sealing element. By varying the rate of compression of the element, the rate of radial expansion of the corresponding portions of the element may also be controlled. Additionally, the rate of radial expansion may also be controlled by controlling the direction and amount of radial expansion along the length of the sealing by reinforcing certain portions of the sealing element while decreasing the rigidity of the reinforcement for other portions.

Abstract: An expandable threaded connection between segments of expandable tubulars that provides a high bearing pressure seal at a specific area along the pin and box members is disclosed. The invention utilizes first and second "grooves" in a surface of the box member and corresponding first and second "ribs" on the pin nose. The radial expansion of the tubulars causes the pin to become shorter in length, thereby causing the pin nose to retract from the back of the box member. As the pin nose retracts, a high bearing pressure, metal-to-metal seal, is formed between elements of the mating tubulars.

Abstract: Embodiments of the present invention generally relate to extendable cutting tools for use in a well bore. In one embodiment, a tool for use in a wellbore includes a tubular body having a bore therethrough, an opening through a wall thereof, and a connector at each longitudinal end thereof; and an arm. The arm is pivotally connected to a first piston and rotationally coupled to the body, is disposed in the opening in a retracted position, and is movable to an extended position where an outer surface of the arm extends outward past an outer surface of the body. The tool further includes the first piston. The first piston is disposed in the body bore, has a bore therethrough, and is operable to move the arm from the retracted position to the extended position in response to fluid pressure in the piston bore exceeding fluid pressure in the opening. The tool further includes a lock operable to retain the first piston in the retracted position; and a second piston operably coupled to the lock.

Abstract: A latch (116) and method for use is provided for latching an item of oilfield equipment (104). The latch has a housing (114) containing a latch member (116), and the latch member is movable between a radially engaged position in which it is engaged with the item of oilfield equipment, and a radially retracted position in which it is disengaged from the item of oilfield equipment. An actuator is configured to drive the latch member into the radially engaged position. Further, the actuator (118) is configured to drive the latch member toward the radially retracted position.

Abstract: An expandable threaded connection between segments of expandable tubulars that provides a high bearing pressure seal at a specific area along the pin and box members is disclosed. A first tubular segment has a pin member and a second tubular segment has a box member. The pin member includes threads, a pin nose and a groove formed in the pin nose. The box member includes a rib and threads that engage with the pin member. The rib can rest within, and contact, a portion of the groove when the threaded connection is made up prior to expansion. The groove is sized to allow the rib to move within the groove, from a contact point at a first end of the groove to a second contact point at a second end of the groove, resulting from axial movement of the pin nose during radial expansion of the connection.
