Port Collar

DEW engineered a cementing equipment product line to fulfill current cementation challenges. All our cementing accessories are fully compatible with our Liner Hanger system.

The Port Collar is used for multi stage cementing. It can be hydraulically or mechanically operated according to the well configuration and cement design. The Port Collar provides control (open-close) to a port in the liner string to allow annulus cementation (e.g. above External Packer elements).

The Port Collar aluminium inserts are PDC drillable
  • Can be opened and closed to squeeze/circulate from inside CSG to annulus (stage cementation)
  • PDC drillable aluminium inserts
  • Improved wall thickness for an easy rig up and make up  torque with common makeup
  • Anti – rotating profile in all parts during the redrilling phase allows easy drilling (PDC)
  • Internal ACME threads provide high tensile strengths
  • Run with DEW Liner Hanger and our special dual wiper plug in one step
  • Mechanical open/close system
