APPLICATION
8-series Stage Tool is designed to ensure cement integrity in wells that require selective zonal isolation. The tool is run with the corresponding open-hole packer. When the ball is dropped and then lands on the circulation sub, increased internal casing pressure hydraulically sets the open-hole packer, opens the stage tool, enabling circulation and then cement to pass though the ports into the annulus above the packer. The plug when released, pushes the slurry and wipes the casing ID clean of cement before bumping on а landing seat. lncreased pressure shifts the closing sleeve downward and closing the tool. Locking mechanism ensures the Stage tool is in closed position.
- Collar cemented casing / liner applications.
- Vertical, directional and horizontal wells.
- Hydraulically actuated tool.
- Adjustable activation pressure.
- Locking mechanism holds the tool in open/closed position.
- AII internal components are РDС drillable.
- After the WOC period, the milling of the technological elements of the collar is required.
- Guiding screws eleminate rotation during mill out operations.
- Full-bore ID after milling.
- Stage Tool withstands high tensile loads.
- Stage Tool withstands high differential pressure.
