 Roller cone to PDC

 

Higher ROP, Greater Footage, Improved Drilling Economics

 

Building on three decades of continuous improvement, we introduce the next generation of PDC technology: premium PDC.
 

With the introduction of PDC, we continue our tradition of innovation by offering a line of bits capable of drilling further, faster through the toughest, most abrasive formations. Our  PDC is setting footage and ROP records seemingly impossible just years ago.
 

With the introduction of our application-specific PDC bit, tougher cutters and improved stability nearly doubled ROP through the Granite Wash at 30 ft/hr. Now, PDC bits have pushed the performance even greater, drilling the tough formation at an average ROP of 41.8 ft/hr or 156% faster compared with the roller cone average .
 

Quantec PDC innovations are based on: 
1. 129,737 work hours 
2. 6,000 feet of rock drilled in our drilling lab 
3. 4,000 hours of lab time 
4. 2,500 hours in simulator and rig tests 
5. 2,400 field runs with ROSCHEN cutters

 

ROSCHEN PDC
Bit: 7 7/8-in.
Formation: Limestone, dolomite, shale

Challenge: Drill through the abrasive Granite Wash in One Fast Run™, decreasing the number of bits used in this interval and reducing trip time; reduce vibration; improve stability; eliminate lost circulation.
 

Results: Quantec technology met all of the operator objectives, drilling through the Prue, Cherokee, Red Fork, and Atoka abrasive formations in one run and eliminating at least one trip. The robust cutting structure, designed specifi cally for this application with the strategic placement of cutters through diamond volume management, drilled 2,785 ft compared with 1,099 ft for the average of the offsets. Drilling hours increased 122%; ROP 8%.
