Value to client
- Rapid 17 ½” drill out in 20 minutes
- Hard, good quality cement confirmed through retrieval of a CoreCure® sample from the 22” shoe
- Downhole temperature logger data revealed QuikCure® heat sweep starting with 75°C (167°F) at surface was delivered to the shoe at 37°C (99°F), equivalent to -4 hours WOC to develop 100psi for tail slurry or -16 hours WOC reduction to develop 500psi for lead slurry near mudline
