Abstract
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.
