  • Publication number: 20140116717
    Abstract: A system and methodology facilitates utilization of a valve of a type which may be used as a subsea test tree. The valve comprises a valve element pivotably mounted in a housing having a passageway therethrough. The valve element may be actuated between an open position and a closed position blocking the passageway. A cutter is disposed along a first surface of the valve element and a seal system is positioned for engagement with a second surface of the valve element to provide separate cutting and sealing surfaces. Actuating the valve element from the open position to the closed position enables cutting of a conveyance, that may be positioned through the passageway, while simultaneously forming a seal along a separate surface to sealingly block the passageway.

Compositions of the invention may exist in a variety of morphologies, including a reactive metal or degradable alloy processed into an alloy of crystalline, amorphous or mixed structure that may constitute the matrix of other composition, for instance a composite. Methods of using apparatus comprising a composition, particularly in oilfield operations are also described (e.g. flow and displacement control, sensors, actuators). This abstract allows a searcher or other reader to quickly ascertain the subject matter of the disclosure. It will not be used to interpret or limit the scope or meaning of the claims.

  • Publication number: 20140000908
    Abstract: An actuating method includes applying an input pressure to a first side of a tool operator and to a second side of the tool operator and moving the tool operator from a first position to a second position in response to depleting the input pressure applied to the second side. A state of a tool element can be changed in response to moving the tool operator from the first position to the second position. The input pressure may be depleted from the second side of the tool operator by transferring hydraulic fluid to a confined diameter container disposed in an annular region of the actuating device or to the first side of the tool operator.

  • Publication number: 20130255963
    Abstract: A technique that is usable with a well includes deploying a plurality of location markers in a passageway of the well and deploying an untethered object in the passageway such that the object travels downhole via the passageway. The technique includes using the untethered object to sense proximity of at least some of the location markers as the object travels downhole, and based on the sensing, selectively expand its size to cause the object to become lodged in the passageway near a predetermined location.

  • Publication number: 20130220609
    Abstract: Methods include introducing a casing into a wellbore penetrating a subterranean formation, the casing forming an annulus with the wellbore surface, where the casing is subject to a first pressure value at a distal end and a second pressure value at a proximal region within the casing, and where a shoe is positioned at the distal end of the casing. Then, placing a sealable valve within the proximal region of the casing, injecting a first cement composition into the casing, through the sealable valve and shoe, and into the annulus, and the placing a second cement composition in a medial region of the tubular formed between the distal end and the proximal region. Afterward, the sealable valve is closed.

  • Publication number: 20130062071
    Abstract: A technique facilitates controlling flow in a wellbore with a simplified valve. The design of the valve also enables reduction in the overall length of the valve to improve spatial considerations. The valve comprises a valve component, e.g. a flapper, movable between a closed position and an open position. A flow tube is designed to selectively open the valve component with reduced travel, thus enabling a shortened flow tube. The short flow tube enables use of valve housings, springs, and other valve components having a reduced length.

  • Publication number: 20130032337
    Abstract: An explosive pellet for characterizing a fracture in a subterranean formation is provided. The pellet can include a casing having a detonation material and an explosive material disposed within the casing. The pellet can also include a nonexplosive material moveably disposed within the casing. Movement of the nonexplosive material can generate a predetermined amount of energy in the form of friction-generated heat sufficient to detonate the explosive material.

  • Patent number: 8322447
    Abstract: An apparatus that is usable with a well includes an operator and a generator. The operator is disposed in the well and configured to respond to a differential pressure between hydraulically isolated zones of the well to produce mechanical motion. The generator is disposed in the well to convert the mechanical motion into electricity. A method that is usable with a well is provided including maintaining hydraulic isolation between a first and second zone of a well. While maintaining the hydraulic isolation, the method further includes producing a mechanical motion in response to a differential pressure between the first and second zones and generating electricity in response to the mechanical motion.

  • Publication number: 20120285702
    Abstract: A technique facilitates actuation of a downhole tool in a well string. The downhole tool may be actuated hydraulically via the controlled flow of a hydraulic fluid under pressure to the downhole tool through a port. Flow of the pressurized fluid through the port is controlled by a barrier member which may be opened by a plunger working in cooperation with the barrier member. Movement of the plunger is controlled by selectively increasing the pressure acting on the plunger through, for example, actuation of an expansion device or other suitable device.
