Customer Challenges
- On their most recent subsea well, PCCMO used a 17 ½” x 19 ½” UR BHA to drill & clean out the 22” conventional shoetrack, taking seven hours
Expro Excellence
- Clinical SeaCure® N2 foamed cement job delivery enabled a rapid 17 ½” drill out in 20 minutes with no cement sheath concerns
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
