Challenge: Reduce construction time while
drilling horizontal wells to access more pay zone in a complex reservoir.
Solution: Design application-specific BHAs
that included the PowerDrive X6 vorteX motorized RSS, PowerDrive Archer vorteX
motorized high build rate RSS, PowerDrive X6 RSS, Smith Bits 8 1/2-in MDSi616
PDC drill bits, ImPulse integrated MWD platform, TeleScope high-speed
telemetry-while-drilling service, and a saturated salt mud system from M-I
SWACO, a Schlumberger company.
Results:
- Drilled the 1,412-m [4,634-ft] pilot hole in a single run at average
ROP of 20.4 m/h [66.9 ft/h]
- Achieved a field record for footage drilled in a day
- Eliminated multiple runs that would be required using a
positive-displacement motor (PDM), saving 9 days of rig time and USD
117,000
