  • Downhole tool consistent fluid control
    Patent number: 9719325
    Abstract: A downhole apparatus for use in a wellbore includes a housing having at least one passage or cavity capable of receiving a fluid. The downhole apparatus further includes an orifice in fluid communication with the passage or cavity. A viscosity-altering member is positioned in proximity to the orifice and is capable of being activated to change the viscosity of the fluid and thus a rate at which the fluid is able to pass through the orifice.
    Type: Grant

  • Rotational wellbore test valve
    Patent number: 9428990
    Abstract: A rotationally activated downhole well valve for connection in a tubing string is disclosed that can be repeatedly opened and closed selectively to place the tubing string in communication with the annulus. The valve is moved between the closed position and the open position by rotating the string in the first direction.

  • Pump through circulating and or safety circulating valve
    Patent number: 8973663
    Abstract: According to one embodiment, a recirculation safety valve is disclosed. The valve has a tubular body with mandrel that is axially shifted in response to annulus pressure. Shifting of the mandrel can either close a safety valve or close a safety valve and open a recirculation port. The valve has an annular actuation chamber that relieves that pressure to prevent inadvertent shifting of the mandrel.

  • Rotational test valve with tension reset
    Patent number: 8662180
    Abstract: According to one embodiment, a rotationally activated downhole well valve for connection in a tubing string is disclosed that can be repeatedly opened and closed selectively to place the tubing string in communication with the annulus. The valve is moved between the closed position and the open position by rotating the string in the first direction. In another embodiment, the valve is opened and closed by rotating the string in the first direction and is reset in the closed position by lifting and lowering the tubing string.
