摘要： A bottomhole assembly for deployment within a wellbore string disposed within a wellbore. The assembly comprises a first mandrel; a second mandrel including a locator for becoming disposed within a locate profile of the wellbore string; a shifting tool including a first gripper surface and a second gripper surfaces; a first shifting tool actuator and a second shifting tool actuator that are translatable with the first mandrel. The shifting tool is displaceable in response to urging by the first shifting tool actuator and the second shifting tool actuator to become disposed in gripping engagement with a flow control member. The second mandrel includes a retainer for limiting displacement of the shifting tool, relative to second mandrel, in both downhole and uphole directions.

摘要： A flow control apparatus is provided comprising: a housing including a port; a housing passage disposed within the housing; a flow control member, displaceable, relative to the port, for effecting opening of the port; and a co-operating member. The flow control member and the co-operating member are co-operatively configured such that displacement of the flow control member, relative to the port, is with effect that a force is applied by the flow control member to the co-operating member, with effect that a seating surface is obtained for receiving a flow communication interference body that is being conducted through the housing passage. The seating surface is obtained in response to a deformation effected by the applied force.

摘要： A fracturing valve comprising a tubular mandrel having a through bore continuous with a tubing string, and a frac window through the side of the tubular mandrel. An outer sleeve is radially disposed around the tubular mandrel. The outer sleeve includes a sleeve port in a sidewall. The tubular mandrel slides relative to the sleeve by application and release of set down weight on a coiled tubing string. When the valve is closed, there is no fluid communication from the tubing string out of the frac window. When the valve is open, fluid communication from the tubing string is enabled. The valve may be installed in a downhole tool having a perforation device. The tool string can be used with one sealing element as the tool is pulled up the hole isolating lower perforations, or with two sealing elements to allow pin-point treatments isolating perforations both up and downhole.

摘要： A bottomhole assembly for deployment within a wellbore is disclosed. The wellbore string includes a port and a flow control member, wherein the latter is displaceable to open and close the port. The flow control member comprises a first mandrel; a second mandrel including a locator for disposition within a locate profile of the wellbore string to resist displacement of the second mandrel, relative to the locate profile, and locating the bottomhole assembly within the wellbore string. A shifting tool is disclosed, the shifting tool including two gripper surfaces; and two shifting tool actuators, translatable with the first mandrel. The shifting tool actuators displace the shifting tool by displacing the first mandrel downhole or uphole relative to the second mandrel; and the second mandrel includes a retainer for limiting displacement of the shifting tool, relative to second mandrel, in both of downhole and uphole directions.

摘要： An actuation dart for deployment down a tubing string installed within a wellbore and provided with one or more valve assemblies is provided. The actuation dart includes a dart body adapted to be carried down the tubing string to the valve assembly via fluid flow. The dart body has a shifting head provided at a first end of the dart body, the shifting head being configured to engage and shift the valve assembly in the open configuration to enable fluid injection in a reservoir surrounding the wellbore. A method for hydrocarbon recovery from a wellbore using the actuation dart is also provided, along with a wellbore system adapted to receive the actuation dart.

摘要： A method is disclosed for improving heat exchange between a geothermal reservoir and a wellbore. The method comprises injecting a stimulating fluid into the reservoir at a plurality of locations along a wellbore to improve conduction of heat to the near wellbore region for circulation of a working fluid to collect reservoir heat and bring to surface for energy generation.

摘要： There is provided a flow control apparatus configured for optimizing use of available space within the wellbore for conducting of fluids between the surface and the subterranean formation. The flow control apparatus is useable for conducting all forms of fluid, such as, for example, liquids, gases, or mixtures of liquids and gases. As well, the flow control apparatus is useable for effecting injection of fluid (e.g. a fluid for stimulating hydrocarbon production via a drive process, such as, for example, waterflooding, or via a cyclic process, such as “huff and puff”) into the subterranean formation, and for receiving production of fluid (e.g. hydrocarbon material) from the subterranean formation (including production that is stimulated by gas lift).
