摘要： Embodiments herein relate to apparatus for selecting between direct manipulations of a downhole tool and shifting of the operational mode of a downhole tool, and more particularly to a mode selector tool coupled with a J-Slot mechanism for the downhole tool, the selector enabling either an unimpeded shifting of, or a locking, of the J-Slot mechanism and connected downhole tool.

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.

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 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： A flow monitoring system can have a plurality of sensors located at monitoring locations along a tubing string inserted into an injector well of a secondary recovery operation. The sensors are configured to monitor a measurable property of fluids flowing in a bore of the tubing string or in an annulus formed between the tubing string and injector bore to determine the presence of said injected fluids at each sensor. At least two fluids having different values of the measurable property are injected into the injector well in an alternating manner and at a known injection rate. The flow rates of the fluids out of various injection zones of the injection well can be calculated using the arrival times and the known injection flow rates of the fluids, cross-sectional area of the fluid conduit(s) through which the fluids travel, and distances between the sensors or between surface and the sensors.

摘要： Embodiments of a bottomhole assembly (BHA) for completion of a wellbore are deployed on electrically-enabled coiled tubing (CT) and permit components of the BHA to be independently electrically actuated from surface for completion of multiple zones in a single trip using a single BHA having at least two electrically-actuated variable diameter packers. One or both of the packers may be actuated to expand or retract for opening and closing off a variety of flowpaths between the BHA and the wellbore, in new wellbores, old wellbores, cased wellbores, wellbores with sleeves and in openhole wellbores. Additional components in the BHA, which may also be electrically—actuated or powered, permit perforating, locating of the BHA in the wellbore such as using casing collar locators and microseismic monitoring in real time or in memory mode.
