Landing Collar

Usually the Landing Collar is located close above the Float Collar or, in the case a Float Collar is not required, above the Float Shoe. After detachment the Wiper Plug lands in a special aluminium seat with an integrated anti-rotating profile inside the Landing Collar. The seat provides full bore sealing to perform a pressure test after cementation and is PDC drillable.

The Landing Collar can be equipped with a shearable or non-shearable ball seat to build up pressure between the bushing and the ball seat for setting any hydraulic components.
The Landing Collar has been designed for optimal bypass flow area between open hole and casing.

  • Receives the Wiper Plug after cementation
  • Anti rotating aluminium profile for Wiper Plug provides easily PDC drillable
  • Latches provide mechanical safety in case of back pressure
  • Can be used with DEW Port Collar for two-stage cementation
