APPLICATION

  • Hydraulically actuated tool.
  • Adjustable activation pressure. 
  • Locking mechanism holds the collar in open/closed position. 
  • Tool cannot bе used in а conjunction with Liner Hanger. 
  • AII internal components are PDC drillable. 
  • Full-bore ID after milling

M-series Stage Collar 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 оn 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 оn 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.
