Customer challenges
- Long conductor wait on cement with G-neat slurry and the requirement for either a clean out trip to drill ahead with 8 1/2" pilot hole or major risk of stuck BHA without a clean out trip
Expro Excellence
- QuikCure® reduced the conductor WOC and SeaCure® provided zero shoetrack solution for optimized drill out of 8 1⁄2”pilot hole BHA through 20” AND 13 3/8” shoetracks
Value to client
- Reduced conductor WOC time by ~50% with data capture evidence to show cement hydration at just 3 hours after placement of QuikCure® heat sweep
- Drilled out 20” shoe in 15 minutes with 8 1⁄2” pilot BHA – removing the requirement for dedicated clean out run / major risk
- Allowed 8 1⁄2” pilot hole drill ahead of 13 3/8” surface casing shoe with no BHA failure and bit drilled > 7,000 to section TD in one run, pulling 1-2 on dull grade
- Surface casing pressure test carried out on green cement with SeaCure® inner string to 2500psi prior to running BOP
- Saved rig time by utilizing the same simple cementing stand for conductor and surface casing cement jobs
