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.
Features
- 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
Benefits
- 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
Applications
- Allows fluid to exit the string above a Packer or other similar type tool
- Jetting, Circulating, Tripping Dry Pipe
Operational
