    摘要: A thermal expansion system for actuating a remote operated sleeve assembly to open and close ports in a housing for fluidly communicating between a bore of a tubular string in a wellbore to the formation utilizes actuation of a propellant charge to create expanding gas and heat in a combustion chamber to directly act on one side of a piston connected to an axially moveable sleeve supported in the housing to shift the sleeve in one direction. Ignition of another propellant charge in a combustion chamber on an opposing side of the piston is used to directly shift the sleeve in an opposing direction.

    摘要: A bottom hole actuator tool for locating and actuating one or more sleeve valves spaced along a completion string. A shifting tool includes radially extending dogs at ends of radially controllable, and circumferentially spaced support arms. Conveyance tubing actuated shifting of an activation mandrel, indexed by a J-Slot, cams the arms radially inward to overcome the biasing for in and out of hole movement, and for releasing the arms for sleeve locating and sleeve profile engagement. A cone, movable with the mandrel engages the dogs for positive locking of the dogs in the profile for sleeve opening and closing. A treatment isolation packer can be actuated with cone engagement. The positive engagement and compact axial components results in short sleeve valves.

    摘要: A sleeve assembly has a sleeve axially moveable within a housing, the sleeve being positively locatable within a wellbore for reliable axial shifting of the sleeve between an uphole position and a downhole position. Stops and shoulders, which delimit the shifting of the sleeve between open and closed positions, are located in an annulus between the sleeve and the housing. Uphole and downhole ends of the sleeve and the housing have opposing ramps formed thereon. Locating shifting tools run through the sleeve assembly are engageable only in a locating profile in the sleeve and cannot engage in the annular stops or in gaps formed in the bore, uphole and downhole of the sleeve, as the ramps act to guide the locating tool therethrough. As the uphole and downhole sleeve ramps converge toward either of the uphole or downhole housing ramps during shifting thereof, debris is diverted into the bore allowing the sleeve to shift fully uphole or downhole.

    摘要: A bottom hole assembly (BHA) located on a tubing string for use in a wellbore having an instrumentation sub and a mechanical fracturing/shifting tool for actuating sleeve valves located along the wellbore. The instrumentation sub is connected to surface via a wireline. Sensors can be located on the BHA for collecting data regarding parameters of the BHA and wellbore and transmitting the data to surface in real-time or near real-time. The instrumentation sub can have an electrical throughput to permit electrical components to be connected downhole of the instrumentation sub. A short-hop system can bridge communication of data above and below the mechanical shifting tool, such that measurements of sensors downhole of the shifting tool can be wirelessly transmitted to the instrumentation sub uphole of the shifting tool. Dimensions of a bore of the BHA can be selected to permit fluid flow at fracturing rates.

    摘要: A bottomhole assembly (BHA) located on a conveyance string for actuating downhole tools in a wellbore, such as sleeve valves. The bottomhole assembly has a shifting tool that is capable of being hydraulically actuated independently of a mechanically actuated treatment tool also located on the BHA. The shifting tool has hydraulically actuated shifting dogs for engaging with the sleeve valves, and a shifting-assist mechanism for applying a downhole force on the BHA. The treatment tool is mechanically actuated via manipulation of the conveyance string to isolate the wellbore, for example to treat a formation through an opened sleeve valve. A hydraulically cycled flow control valve can be located on the BHA for more convenient control of the fluid flow and pressure in the BHA. The BHA can also have a repositioning mechanism for positioning the shifting tool downhole of an opened sleeve valve without requiring repositioning of the entire BHA.

    摘要: One or more remote-operated sleeve valves are placed along a tubular string downhole. The sleeves can be opened and closed wirelessly, and in embodiments over and over again. Differential pressure between wellbore fluid pressure and an accumulator chamber enable repeated shifting. Each sleeve can have a unique actuation code removing constraints regarding sequence of operation and need for well intervention to access the sleeves. Hydraulic fracturing can be achieved without wellbore obstructions, and other operations benefit for reduced expense in service rigs and the ability or selectively shut off problem zones. Remote signals received downhole include those generated by percussive and seismic, distinguishable from background noise including during pumping.
