  • Publication number: 20190186236
    Abstract: A valve assembly for use in controlling flow of a fluid in a wellbore includes a housing including an internal passageway, a conductor located adjacent to the internal passageway, a rotor assembly located outside of the internal passageway, and a flow path to receive a flow of the fluid therethrough to rotate the rotor assembly. The rotor assembly includes a magnet having a magnetic field and rotatable with the rotor assembly, where rotation of the rotor assembly and the magnet relative to the conductor produces electrical energy in the conductor.

  • Publication number: 20190153788
    Abstract: A releasable connection mechanism for use downhole with a tubular member includes a collet, a collet stop, and a ring housing. The collet is configured to engage the tubular member, the collet stop is axially movable with respect to the collet between a disengaged position to not engage the collet and an engaged position to engage the collet, and the ring housing is selectively axially movable with respect to the collet. In the disengaged position, the collet is configured to move with respect to the ring housing to engage the ring housing and prevent the collet from disengaging the tubular member when the collet is tensioned with respect to the tubular member. In the engaged position, the collet is configured to remain axially stationary with respect to the ring housing and disengage the tubular member when the collet is tensioned with respect to the tubular member.

  • Patent number: 10287851
    Abstract: A method of actuating a selected electrically powered device such as a solenoid operated valve (SOV) among a plurality of electrically powered devices coupled between a first conductor and second conductor includes applying a high voltage differential between the first conductor and the second conductor, the high voltage being at least as high as the breakover voltage of a switching thyristor coupled to the selected electrically powered devices. The method also includes applying a low voltage differential between the first conductor and the second conductor after applying the high voltage, the low voltage being lower than the breakover voltage of any switching thyristor coupled to the plurality of electrically powered devices.

  • Publication number: 20190071960
    Abstract: Systems and method for injection a chemical into a wellbore. A chemical injection system may comprise a first valve, a chemical line, a pilot line, an injection line, and a backflow prevention valve disposable in the injection line. A production fluid recovery system may comprise a chemical injection system, a first valve, a pilot line, an injection line, a backflow prevention valve, a production tree, a wellhead, and production tubing. A method for actuating a valve in a chemical injection system may comprise pushing a fluid into a chemical line, pressurizing a pilot line to open a first valve, pushing the fluid through the first valve, increasing pressure in the pilot line to open a second valve, pushing the fluid through the second valve, pushing the fluid through a chemical line, and injecting fluid into a wellbore from the chemical line.

  • Publication number: 20190017368
    Abstract: A system and method for a position sensor system in a well system. A position sensor system may comprise a downhole tool, a position sensor attached to the downhole tool such that resistance of the position sensor changes with position of the downhole tool, a first conductor attached to the position sensor, and a second conductor attached to the position sensor as an electrical ground. A method for determining position of a downhole tool may comprise taking a first measurement of a line resistance and moving the downhole tool, wherein moving the downhole tool increases or decreases the line resistance. The method may further comprise taking a second measurement of the line resistance, wherein the second measurement provides an indication of the position of the downhole tool.

  • Publication number: 20180163521
    Abstract: A flow control assembly having a body defining a central flow passage and one or more lateral flow openings that facilitate fluid communication between the central flow passage and an exterior of the body, and a flow trim positioned within the central flow passage and defining one or more flow orifices aligned with the lateral flow openings. A flow closure member is positioned within the central flow passage and movable between a closed position, where the lateral flow openings and the flow orifices are occluded to prevent fluid flow through the lateral flow openings, and an open position, where the lateral flow openings and the flow orifices are at least partially exposed to facilitate fluid flow through the lateral flow openings. A sacrificial nose radially interposes the flow closure member and the flow trim to mitigate erosion of the flow closure member.
