Torque ft-lb Increase ROP Drilling Challenges in 2017 2005 2010 2017 Horizontal: 30 FPH - 120 FPH Motor runs: 80 hrs - 200-300 hrs Days per well: - BHA for curve & lateral: 20 days 6-7 days multiple - generally 1 1995 2017 2020 4-3/4" (5") 1,500-2,000 5,000-8,000 16,000 6-3/4" (7") 4,000-7,000 12,000-24,000 45,000
Alternative Designs to address Challenges Percussion Drilling Increased ROP by 30% to 50% Less torque requirement thus Less reactive torque Better steerability Less rotational horsepower requirements at the bit High Speed Drilling High speed drilling with an expected bit speed of app. 800 RPM Currently 120-300 RPM bit speed + 80-120 RPM DP rotary Future 750 RPM bit speed + 40 RPM DP rotary
Drilling Hammer Trends The pace of drilling an oil or gas well with conventional mud motors is reaching technical limits. Ashmin has combined the function of a percussion hammer with the rotational action of a drilling motor to further increase drilling efficiency We call it the HammR Drill
