  • Patent number: 9091147
    Abstract: A downhole fluid flow control system (100). The downhole fluid flow control system (100) includes a flow control component (122) having an internal flow path (134) and a temporary sealing substance (136) disposed within the internal flow path (134). During installation of the downhole fluid flow control system (100) in a well, the temporary sealing substance (136) prevents fluid flow through the flow control component (122), which prevents plugging or clogging of the internal flow path (134). After installation, the temporary sealing substance (136) degrades when exposed to a water source in the well, which enables fluid flow through the flow control component (122) and thus proper operation of the fluid flow control system (100).

    Abstract: An object launching apparatus for a well has a housing, a flow mandrel, and a cage. The flow mandrel is disposed in the housing's internal chamber, and a flow passage in the mandrel communicates flow from the housing's inlet to the mandrel's flow port, which in turn communicates with the housing's outlet. The cage is disposed in the internal chamber and defines pockets for holding the objects. A motor and shaft move the cage in the housing relative to the mandrel's flow port so the cage's pockets can be selectively positioned in communication between the mandrel's flow port and the housing's outlet. This allows any of the object(s) held in the positioned pocket to be launched into the flow to the well. Preferably, the motor rotates the shaft so the cage can ride linearly along the shaft's thread and the cage can rotate through a cammed engagement with the housing.

A control mechanism is provided and is configurable to prevent the under-reamer cycling between the first and second configurations and thus maintain the under-reamer in a selected one of the first and second configurations.

  • Patent number: 8978776
    Abstract: An expandable tubular to be used within geologic structures and a method of manufacturing thereof has a substantially tubular shaped member with an axis extending therethrough. The tubular member has one or more helical member formed within a wall of the tubular member, and the helical member may be defined about the axis of the tubular shaped member. Further, a plurality of elongated perforations are formed within the wall of tubular member, and the tubular member is compressible from a larger diameter to a smaller diameter. When compressed, the tubular member stores expansive energy within the wall, in which the tubular member may then expand back to a larger diameter when the expansive energy is released.

  • Patent number: 8978777
    Abstract: A non-rotation lock screw for a wellhead assembly is provided that includes a rotating portion and a non-rotating portion. The non-rotating portion includes a distal end configured to engage a component of the wellhead assembly, and may include one or more seals. The rotating portion may be rotating into a component of wellhead assembly such that the non-rotating portion translates in a radial direction. The rotating portion and non-rotating portion may be coupled together via a bearing to enable free rotation of the rotating portion. Systems and methods of operation that include the non-rotation lock screw are also provided.

  • Publication number: 20150068740
    Abstract: A coaxial ground heat exchanger and installation method are disclosed where the heat exchanger has a central core tube that can be provided with a thermally insulating casing and an outer tube that delimits an annular gap which extends radially outwards from the core tube. The core tube and the annular gap can be configured such that a flowable heat transfer medium can flow through. The outer tube is formed by a tubular expandable cover that directly adjoins a wall of a ground heat exchanger borehole when the heat exchanger is installed.

  • Publication number: 20150060076
    Abstract: A method and apparatus for selectively actuating a downhole tool in a tubular conduit. An actuator tool has an actuator mandrel having an actuator bore through and a bypass and a profile key to selectively engage the downhole tool. The downhole tool has one or more profile receivers adapted to actuate the downhole tool. The actuator tool is conveyed into the tubular conduit and the actuator tool and the downhole tool are engaged if the profile key and the profile receiver match, and the actuator tool and the downhole tool are non-engaged if the profile key and the profile receiver do not match. Fluid may be circulated through the actuator bore to flush or wash ahead of the actuator tool.
