Challenge: Efficiently drill 16-in section in hard anhydrite and dolomitic limestone formations that are prone to stick/slip and decrease ROP.
Solution: Deploy a StingBlade conical diamond element bit and Schlumberger performance mud motor to drill the 16-in section in one run at faster ROP.
Results:
- Completed the 4,770-ft [1,454-m] section in one run.
- Achieved double the ROP in the Rus and Radhuma Formations.
- Increased overall on-bottom ROP by 24% compared with the fastest offset well.
- Saved 3.5 days of drilling time versus AFE.
