  • Publication number: 20150129196
    Abstract: Two control systems are provided to run in parallel between a surface location and the final controlled element, in this case a subsurface safety valve. The primary control circuit is controlling until a predetermined signal is given to the secondary control line which has the effect of actuating the valve a single time against the force of a bias or a shear pin that breaks. The movement of a shuttle in the housing due to the predetermined signal being provided in the secondary line puts the secondary control system in the position of running the tool. The primary system is valved off and cannot return into service. There are just two lines into and out of the housing to make the valve operate at the desired location. A test port is provided for surface testing.

  • Patent number: 9022102
    Abstract: A well installation includes a metallic structure having downhole metallic tubing for conveying product towards the surface, a sub surface safety valve disposed in the downhole metallic tubing for interrupting flow of product towards the surface when closed and allowing flow of product towards the surface when open. Also, valve control means are disposed downhole and arranged for detecting electrical signals in the downhole metallic tubing and for holding the valve open while receiving an electrical signal, and surface signaling means for applying an electrical signal to metallic structure of the well for transmission via the downhole metallic tubing towards the valve control means so as to hold the valve open. The system can be made more robust by ensuring that the control means will only hold the valve open while receiving a signal of given characteristics to help prevent stray currents erroneously holding the valve open.

  • Publication number: 20150027724
    Abstract: A straddle apparatus deploys in a borehole with tubing to treat different zones of a formation. The apparatus has first and second packer elements and a flow element disposed on the apparatus. The first and second packer elements have fill ports in fluid communication with the tubing and have packer valves. These packer valves are biased to open fluid communication between the packer elements and the fill port so the packer elements can be inflated to seal off a section of the borehole when fluid pressure is applied down the tubing string. The flow unit has a flow port in fluid communication with the tubing and has a flow valve biased to close fluid communication between the flow port and the borehole. Once the elements inflate, one or more control units on the apparatus electronically activate the at packer valves to close fluid communication between the packer elements and the fill ports.

    Abstract: An actuator and method for setting a subterranean tool uses an externally mounted actuator on a tubular string that is operably engaged to the tool to be actuated. At the desired location for actuation a signal is given to a valve assembly. The opening of the valve releases the pressurized compressible fluid against a floating piston. The piston drives viscous fluid ahead of itself through the now open valve that in turn drives an actuating piston whose movement sets the tool. The triggering mechanism to open the valve can be a variety of methods including an acoustic signal, a vibration signal, a change in magnetic field, or elastic deformation of the tubular wall adjacent the valve assembly.

According to some embodiments, the types of devices being powered are untethered or otherwise cannot benefit from direct power transmission from the surface. Examples of devices include small devices in downhole environments. Other examples of devices are sensors and other hardware such as flow control valves installed during completion. According to one example permanent and/or semi-permanent monitoring sensors make use of the energy generation techniques described herein.

  • Patent number: 8418770
    Abstract: A valve system has a main valve that is adjustable for output flow and pressure. The system also includes an output flow transducer, an output pressure transducer, and a fluid depth transducer. A microcontroller is operatively coupled to the valve, the output flow transducer, the output pressure transducer, and the fluid depth transducer. The microcontroller operates the valve to selectively control the output flow, the output pressure, and the fluid depth according to inputs received from a user.

  • Publication number: 20130087344
    Abstract: A downhole valve assembly operable to control production fluid flow around an obstruction in a production tubing string. The obstruction may be caused by another valve or valve assembly located in the production tubing string, where the valve is closed and blocks flow through the production tubing. The downhole valve assembly comprises a tubular body that includes an axial passage extending through the body and one or more ports extending substantially radially through the body. The downhole valve assembly also includes one or more actuating members operable to move relative to the body. Movement of the actuating members selectively opens the ports such that a fluid flow path through the ports is defined between an annulus region outside of the valve assembly and the axial passage such that the blockage can be bypassed.

  • Patent number: 8322446
    Abstract: A method of selectively actuating well tools includes the steps of: selecting a well tool for actuation by current flow in one direction through a set of conductors; and selecting another well tool for actuation by opposite current flow through the set of conductors. A system includes multiple control devices that control which well tool is selected for actuation in response to current flow in at least one conductor set. A current direction in the conductors selects a certain well tool for actuation. A method of using n conductors to selectively actuate n*(n?1) well tools includes the steps of: arranging the conductors into n*(n?1)/2 sets; connecting the conductor sets to respective groups of the well tools; and controlling direction of current flow through at least one of the sets of conductors, thereby selecting at least one well tool in the respective group of the well tools for actuation.

  • Patent number: 8286717
    Abstract: Embodiments of the invention generally relate to tools and methods for hanging and/or expanding liner strings. In one embodiment, a method of hanging a liner assembly from a previously installed tubular in a wellbore includes running the liner assembly and a setting tool into the wellbore using a run-in string. The setting tool includes an isolation valve and the liner assembly includes a liner hanger and a liner string. The method further includes sending an instruction signal from the surface to the isolation valve, wherein the isolation valve closes in response to the instruction signal and isolates a setting pressure in the setting tool from the liner string; and increasing fluid pressure in the setting tool, thereby setting the liner hanger.

    Abstract: Well tools including valves operable by low electrical input. One well tool includes a valve which controls fluid communication between pressure regions in a well, the valve including a rotatable member which is biased to rotate, and a brake or clutch which prevents rotation of the member. Another valve includes a barrier which separates reactants, with the valve being operable in response to the barrier being opened and the reactants thereby reacting with each other. Yet another valve includes a barrier which separates the pressure regions, and a control circuit which heats the barrier to a weakened state. Another valve includes a member displaceable between open and closed positions, a restraining device which resists displacement of the member, and a control device which degrades or deactivates the restraining device and thereby permits the member to displace between its open and closed positions, in response to receipt of a predetermined signal.
