Carrol County, Ohio
8.75″ Vertical Section
Ulterra’s 6.75″ Mitigator™
An operator drilling in Carrol County, Ohio wanted to reduce the percentage of DBRs in their 8.75” vertical section.
- Reduce frequency of catastrophic dulls caused by drill bit over-engagement
Collaborating with the customer, our team recommended adding a Mitigator™ to the BHA to reduce torsional shock in the BHA to improve drilling dynamics and bit dull grades.
Across nine runs on air with the Mitigator, this operator:
- Improved outer dull conditions from 5.75 (standard BHA) to 3.2 (with Mitigator)
- Increased average footage drilled from 4,045 ft. (standard BHA) to 4,199 ft (with Mitigator)
