摘要： A valve assembly for integration within a wellbore string disposed within a subterranean reservoir is provided. The valve assembly includes a valve housing having one or more injection ports for establishing fluid communication between a central passage and the reservoir. The valve assembly includes a valve sleeve operatively mounted within the valve housing and comprising a fluid channel adapted to establish fluid communication between the central passage and the injection ports, and configured to create a fluid flowrate restriction. The valve assembly has a flow adjuster connectable to the valve sleeve, and is selectively arranged to align an opening with the fluid channel and allow fluid to flow from the fluid channel through the opening to the injection port, wherein connecting the flow adjuster to the valve sleeve defines a flow length of the fluid channel to adjust the fluid restriction created by the fluid channel.

摘要： 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.
