Challenge: Drill a 1,308-m sidetrack in high
stick/slip environment and with limited rig capabilities.
Solution: Develop a fit-for-purpose,
integrated drilling solution that includes
- PowerDrive Orbit vorteX motorized RSS to improve drilling efficiency
and trajectory control at high rpm
- Directional PDC drill bit from Smith Bits, a Schlumberger company,
that has backreaming cutters and diamond-enhanced gauge protection for superior
durability
- MEGADRIL oil-base drilling fluid system from M-I SWACO, a
Schlumberger company, to optimize drilling performance
Results:
- Increased footage from an average 44 m/d to 132 m/da 300%
increasecompared with footage from offset wells
- Improved ROP from an average 6.8 m/h to 26 m/h, nearly 400%
- Saved 4 drilling days off plan
- Drilled longest sidetrack well in the Samburgskoye oil field
