The Packer Circulating Tool is run with open circulation ports to allow circulation above a packer and to auto-fill the string whilst RIH. When desired the ports can be closed to allow setting of the packer.


  • Single piece body with no internal connections
  • Drop ball activated to close the ports
  • Shear rating can be changed to suit well conditions
  • Large port TFA to allow high surface flowrates


  • Cost Savings
    • Allows circulation between the drillstring and annulus whilst RIH with a packer to depth
    • Auto-filling of the workstring reduces RIH time
  • Increases Well Productivity
    • Allows the well to be circulated whilst RIH to ensure first time deployment of the packer
    • Allows effective displacement of debris that can hinder the deployment of the completion
  • Integrity
    • Available with high torque connections to reduce the need for additional crossovers
  • Reducing Non-Productive Time
    • Allows the lower completion / packer to be RIH first time
    • Prevents premature setting of the packer


  • Allows fluid to exit the string above a Packer or other similar type tool
