Premium
Stratapax Drill Blanks at Work
Diamond Innovations Premium Stratapax Drill Blanks feature a non-planar diamond/carbide
interface, designed to minimize internal stress, improve spalling and chipping
resistance, and provide maximum downhole cutting performance. The combination
of unique interface geometry and diamond properties results in increased ROP,
longer bit life, and reduced WOB in highly demanding drilling applications.

Bits containing Premium 13 mm Stratapax Drill Blank
Cutters drilled more footage in less than half the time, at 40% of the total cost,
compared to bits with non-premium cutters. Drilling was completed in a hard and
dense section of limestone/chalk in the North Sea, with a single 121/4 inch diameter
polycrystalline diamond (PCD) bit. With the high rig rates of North Sea drilling
the results of using Diamond Innovations Premium Cutters showed a cost saving
of over $ 300,000. |
Drilling
cost Comparison
Stratapax Drill Blank Premium Cutters averaged more than twice the rate of
penetration (ROP). The cost per foot was reduced by more than $ 200.

Record
Set in Louisiana
Entire Wilcox Formation Drilled
A 121/4 inch polycrystalline diamond bit, containing Stratapax Premium 13 mm
drill blanks, drilled 6,5 times further than the average offset footage in the
Wilcox formation, and most of the Midway shale before being pulled.
Total footage: 6,5 X greater than average offset |
 |
| Penetration Rates Increased by 12% |
60% Cost per Foot Reduced |
Total Cost Reduced by More Than 65% |

| Stratapax Drill Blanks Premium Cutters were also able to increase the ROP
by 12% over the average application. The Premium Cutters dull graded with less
spalling and chipping of the diamond table. |
Increases in ROP and total footage resulted in a cost per foot reduction of
60% compared to the offset data. |
A cost saving was also obtained by eliminating expensive trip time to change
bits, which resulted in an additional saving of $ 600.000. |
