New Cutter Technology Delivers Record Performance - Dunn County
Operator Record – Fastest 2-mile First Bench Three Forks Lateral
1st Bench Three Forks Lateral Shale/Limestone/Dolomite Moderate UCS/Abrasion/Thermal Moderate/Low Impact
COBRA Cutter Technology
Dunn County, North Dakota
Complete entire 2-mile lateral interval in one-bit run but with enhanced cutting efficiency with added durability to improve Rate of Penetration and reduce the overall time in the hole.
Backed by the methodology of VES’s VENOM Cutter Technology, Applications Engineers strategically placed COBRA shaped cutters into the previously successful baseline F613P2-F bit design. The baseline bit utilized planar cutters in the primary row and was run with success within proximity to this location.
Utilizing in-house proprietary software and analyzing previous dull conditions VES determined the optimal locations to place the cutters for enhanced cutting efficiency.
- The baseline bit with planar cutters (tripped for DTF) was outperformed by the COBRA cutter version by 4,014’ and 15 ft/hr.
- Of the 10 drill-out runs in the area, the VES F613P2-F and F613P2-CF bit runs outperformed the competition. The COBRA bit run outperformed the offset run average by 53% for Footage Drilled and 17% for Rate of Penetration.
The 2nd of the two COBRA bits completed in the 2-mile lateral interval in an Operator Record
for this formation of 45 total hours and 225 ft/hr. This operator has frilled over 900 wells targeting this formation in this basin
