Successful plug performance marks first-ever use of intercept RBP in Azerbaijan and for this operator
Challenges – This was a critical well for the customer. The first branch that was drilled is currently the longest well in the Caspian Sea, with a total depth of 7,411m. The second branch, drilled to a TD of 6,803m, would then have to be completed after a period of BOP (blowout preventer) maintenance.
As completion operations needed to begin immediately after retrieving the RBP (retrievable bridge plug), several meetings, discussions, presentations were carried out to discuss running and retrieval operations. This was the first time that Halliburton had run its 9 5/8-inch Intercept® RBP for Total, and the first time in Azerbaijan.
Solutions – Halliburton proposed using its 9 5/8-inch Intercept RBP, which is API 11D1 Grade V0 and qualified to 7,500 psi (517 bar) with no hang weight requirement. The assembly also has a 400,000-lb tensile capability.
Prior to running and setting the Intercept RBP, an inflow test on the 5 1/2-inch x 7 5/8-inch liner top was required. The test was successfully completed using the reliable, field-proven RTTS® service packer and RTTS circulating valve assembly, allowing the following critical well operations to proceed.
- Run a 9 5/8-inch Intercept RBP
- Pull out BOP for full maintenance
- Install a Christmas tree and BOP
- Retrieve the Intercept RBP
- Run completion equipment
