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: An apparatus and a method of controlling flow communication with an apparatus are disclosed. The apparatus includes a flow communicator, a flow control member, an uphole-disposed flow interference effector uphole of the flow communicator, and a downhole-disposed flow interference effector downhole of the flow communicator. While each of the uphole-disposed flow interference effector and the downhole-disposed flow interference-effector, independently, is contacting the flow control member, the flow communicator is closed. Displacement of the flow control member, relative to the flow communicator, in the downhole direction, opens the flow communicator. While there is an absence of occlusion of the second uphole-disposed flow interference-effecting member of the uphole-disposed flow interference effector, the flow control member is disposable, relative to the flow communicator, such that each one of the second-uphole disposed flow interference-effecting member and the downhole-disposed flow interference-effector, independently, is contacting the flow control member, such that the flow communicator is closed.

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: There is provided a bottomhole assembly that is deployable downhole within a wellbore via a conveyance system. The conveyance system includes a fluid conductor for effecting fluid communication between the surface and the bottomhole assembly. The bottomhole assembly includes an actuator tool and a shifting tool. In some embodiments, for example, the actuator tool is disposed for receiving transmission of a compressive force being applied to the conveyance system from the surface, and transmitting the compressive force for actuating the shifting tool. In some embodiments, for example, the actuator includes an anchoring tool configured for hydraulic actuation, via fluid pressure forces communicated by the fluid conductor of the conveyance system, for becoming retained relative to the wellbore string. In some embodiments, for example, the actuator tool also includes a linear actuator that is extendible relative to the anchoring tool, while the anchoring tool is retained relative to the wellbore string, for transmitting a force to the actuated shifting tool with effect that the shifting tool is displaced relative to the wellbore.
