The following is a procedure example for running and setting a weight set tie-back packer with a 7in liner.
1. Suspend tie-back packer in slips. Make up the running tool on a joint of drillpipe and stab into assembly. Rotate tool to engage lugs, then slack off and rotate the tool to the left 6-7 turns to engage the float nut. Back off the drillpipe joint.
2. RIH assembly on drill collars. Approximately 50 000 lbs slack off is required to set the packer. RIH, making sure that the string does not rotate, i.e. use back up tong.
3. Continue RIH to within a few meters of TOL, break circulation before continuing with RIH.
4. Stop pumps and check weight up and down.
5. Start circulating with a maximum circulation pressure of 200 psi and slowly lower the string, stabbing the seal assembly into the PBR. Observe for a pressure increase as the seals enter the PBR, stop pumps and bleed pressure. Mark pipe.
6. Lower string, ensuring that slacked off length corresponds to the length of the seal assembly. Slack off 2 000 lbs over string weight. Pressure test string to 500 psi,bleed off pressure.
7. Slack off 50 000 lbs to set packer and hold for 15 min.
8. Pull 10 000 lbs over string weight up to ensure packer slips are set.
9. Release setting tool by slacking off 15 000 lbs and rotating the string 10 turns to the right.
10. Pick up to check the setting tool is free but do not pull PBR seals from upper PBR.
11. Close BOP and pressure test annulus to required pressure. Check for returns from string.
12. Open BOP and presure test string to required pressure. Check for returns from annulus.
13. POOH.
