    Abstract: A well completion system for producing fluids from a wellbore provided in a subterranean reservoir is provided. The well completion system includes tubing segments connectable to one another along the wellbore. The tubing segments include injection segments provided along the wellbore in spaced-apart relation to each other, each injection segment has an injection valve toollessly operable between a closed configuration preventing fluid flow into the reservoir, and an open configuration allowing fluid flow into the reservoir. The tubing segments also include production segments provided along the wellbore in a staggered relation with respect to the injection segments and configured to allow fluids received from the reservoir to be produced from the reservoir. The tubing segments each are configured to include injection fluid passages and production fluid passages isolated from one another along the wellbore to enable synchronously injecting and producing fluids to and from the reservoir at respective fractured locations.

    Abstract: A downhole component for integration in wellbore string is provided. The downhole component includes fluid conduits enabling fluid flow therethrough and a sealing element connected to the fluid conduits and operable between a disengaged configuration, where the sealing element is disengaged from an inner surface of the wellbore, and an engaged configuration. The downhole component also includes an actuation assembly having a blocking member releasably secured to the fluid conduits and a fluid-pressure operable actuation member slidably connected to the fluid conduits adapted to engage and operate the sealing element from the disengaged configuration to the engaged configuration. The downhole component has a release mechanism operable to release the blocking member to enable the sealing element to revert to the disengaged configuration, wherein the release mechanism is adapted to be selectively and independently operated relative to additional release mechanisms associated with adjacent downhole components along the wellbore string.

    Abstract: There is provided a downhole tool comprising a locator. The locator includes a wellbore coupler for becoming releasably retained relative to a locate profile; and a wellbore coupler release opposer configured for opposing release of the wellbore coupler from the retention relative to the locate profile. While the opposing of the release of the wellbore coupler from the retention relative to the locate profile is being effected by the wellbore coupler release opposer, relative displacement between the wellbore coupler release opposer and the wellbore coupler is effectible, with effect that the opposing is defeated. The locator also includes a displacement impeder for impeding the relative displacement between the wellbore coupler release opposer and the wellbore coupler.

    Abstract: A high force stroker tool for integration within a wellbore string disposed along a wellbore defined within a subterranean reservoir is provided. The stroker tool includes a hydraulic anchor hydraulically operable to deploy slips securable to the wellbore and to define a mechanical brace, a shifting tool operatively coupled to the hydraulic anchor and comprising a mechanical anchor securable to a movable component, the shifting tool being mechanically operable to move the movable component; and an actuator coupled between the hydraulic anchor and the shifting tool, the actuator being hydraulically operable to brace against the mechanical brace and create a downhole mechanical force adapted to mechanically operate the shifting tool. A method of shifting downhole valve assemblies using the high force stroker tool is also provided.

    Abstract: A valve assembly for downhole completion operations and method for using the assembly is described. The valve assembly relies on non-polymeric interfaces between the valve components for sealing the valves without elastomeric materials, thereby making the valve assembly suitable for high temperature well operations, such as 320 °C to 600 °C, which are typically encountered in geothermal well operations. The valve assembly includes a first seat which receives an actuating member to actuate the opening of ports in the housing, thereby allowing for fluid injection into the formation adjacent the valve assembly through the ports. A seal assembly suitable for use in high temperature well operations is also described.
