  • Patent number: 9890631
    Abstract: A device, system, and method for locating collars along a casing string. The device includes a casing collar locator (CCL) and a valve in communication with the CCL connected to a work string. Fluid is pumped down the work string as the device is used to locate collars along a string. Upon detection of a collar, the CCL sends a signal to the valve, which causes the actuation of the valve to decreases a flow area within a work string. The decrease in flow area causes a pressure increase within the work string, which may be detected at the surface to indicate the detection of a collar. The device may include an amplifier and power source to amplify the signal from the CCL to the valve. The CCL may detect collars by a change in magnetic flux or by the detection of a signal emitted by individual collars.

  • Patent number: 9850719
    Abstract: An apparatus enables modifying a riser's operating parameters for transporting production fluids from a subsea well to an offshore production facility after an initial period of production to address changes over time in the conditions of the reservoir and/or the riser without removing the original riser. An insert riser having a smaller diameter is inserted into the riser after the initial period. The original riser has a recessed seal face for receiving seal element(s) and a recessed lock groove for receiving a locking ring. An intervention coiled tubing having a sleeve removal tool is inserted into the riser to engage a protective sleeve covering the recessed seal face. The tubing is pulled to the floating structure thereby removing the protective sleeve and the temporary retaining ring from the production riser, exposing the recessed seal face. The insert riser can then be inserted into the riser and locked into place.

The sleeve has a bore with an inner circumferential surface comprising an inwardly facing formation adapted to engage with an outwardly facing formation on the body of the downhole device when the body of the downhole device is disposed in the bore of the sleeve. The sleeve is typically deployed in the wellbore at the desired location and is radially expanded by an expander device (2) that is deployed within the bore of the sleeve. The expanded sleeve plastically deforms and retains its expanded configuration after the radial expansion force is removed from the sleeve.

  • Publication number: 20140231079
    Abstract: A velocity sensor, a controller, a plunger lift system and method for controlling a plunger lift system is provided. The velocity sensor can use a first magnetic field sensor and a second magnetic field sensor spaced a sensor distance to determine a velocity of a plunger as it passes the velocity sensor. The controller can use information received from the velocity sensor to both control the operation of the plunger lift system using the measured plunger velocity obtained from the velocity sensor and shut down the well if the plunger is measured travelling to fast.

    Abstract: A method and apparatus for evaluating the subterranean formation of a wellbore is presented. The method includes conveying a downhole tool in a wellbore via a cable, and determining the torque in the cable in real-time. The method further involves conveying the downhole tool on a wireline, and automatically triggering an alert when the torque reaches a certain level. The apparatus includes a cable, a downhole tool attached to the cable for conveyance within the wellbore, and a sensor to measure torque in the cable. The apparatus may also include a telemetry system to communicate the torque data to the surface. The downhole tool includes a sensor to measure the relative torque between the downhole tool and the cable in real time.

  • Publication number: 20140116726
    Abstract: Devices and methods for borehole seismic investigation are provided. The devices are a downhole tool having gripping devices which may improve contact between the downhole tool and the borehole wall (or casing of the borehole wall) and reduce slippage as compared to downhole tools without the gripping devices. The methods involve lowering a downhole tool having the gripping devices into a borehole and applying force to cause the gripping devices to penetrate or create an indentation in the borehole wall (or casing of the borehole wall). The methods and devices may improve the coupling between the downhole tool and surface to be monitored and/or may enhance the frequency range due to higher coupling frequency as compared to downhole tools without the gripping devices.

    Abstract: A running tool has a stem for connecting to a string of conduit, a body, and a plurality of functional positions selected in response to rotation of the stem relative to the body. A feedback mechanism assembly is connected to the running tool and is operational with rotation of the stem relative to the body. The feedback mechanism assembly increases the torque required to rotate the stem relative to the body when the running tool has reached one of the plurality of its functional positions. The increased torque thereby provides a positive indication that the running tool has reached and is in the desired and proper functional position.
