FORTRESS Isolation Valve Shifting Tool | Schlumberger

Primary Shifting Tool

For the FORTRESS premium isolation valve

Open and close FORTRESS valves

Use this tool to open and close the FORTRESS premium isolation valve, even under differential pressure or high-loss conditions. The tool is run on the end of washpipe, a perforating string, or coiled tubing, and the tool's shifting profile is designed to minimize risk of interference or engagement with profiles of other completion technologies.

When the tool passes through the valve, it engages the shifting profile, opening the valve or closing it and creating a gas-tight seal. The washpipe and tool are then retrieved.
