Counterforce® Technology by Ulterra

A patented PDC bit technology which utilizes a unique cutter configuration to lower bit reactive torque and vibration, dramatically improving drilling efficiency. Unlike traditional PDC bits, the cutters of this step-change advancement work together to lower lateral vibration and increase crack propagation. The CounterForce cutting structure is engineered to slice through rock while maintaining a more consistent torque signature thus increasing stability and ROP.

CounterForce re-directs lateral forces to fail rock, not your bit. Unrestrained lateral forces, particularly in high-speed directional wells, generate excessive vibration that, at best, puts the brakes on optimum drilling efficiency, but at worse, can prematurely destroy a premium PDC bit.

With CounterForce, Ulterra has given new meaning to groundbreaking PDC bit technology with a unique cutter configuration that minimizes torque and vibration to deliver unequaled lateral stability, more footage, and cost-effective drilling rates. The patent-pending CounterForce is a true step-change advancement in PDC bit design.

Unlike conventional PDC bits, CounterForce technology employs a novel cutter orientation where the cutters work together, forcing the bit to essentially grasp the bottomhole pattern, giving it the traction and stability necessary to handle otherwise destructive and efficiency-robbing lateral vibration. CounterForce reins-in lateral forces, re-directing them from the bottomhole assembly into the formation where they work to your advantage by failing rock and removing it from the hole much more efficiently. The exclusive cutter angle arrangement produces a reliable bit that slices the formation and remains sharper, longer, delivering higher penetration rates while saving you the costs of unnecessary bit trips.

Results from hundreds of wells, comprising more than one million feet of hole, document the capacity of CounterForce PDC bits to consistently reduce torque and vibration problems, improve directional control, and exhibit near-green end-of-run dull conditions. In multiple applications, CounterForce has routinely delivered exceptional drilling rates, up to 50% faster than the best available offset, saving operators tens of thousands of dollars and as much as a full day of drilling.

What sets CounterForce® apart?


Compare CounterForce® Configuration

CounterForce® technology is the answer to minimizing PDC bit vibration for increased drilling efficiency. Now, you can significantly reduce vibration that causes below-average drilling performance while destroying premium PDC bits. Applying patented cutter orientation, the technology redirects vibration from the bottomhole assembly into the formation so you can improve toolface control, enhance the bit life and dull condition, and raise ROP. CounterForce technology is field-proven with almost 100 million feet of hole drilled, including vertical wells, curves, and laterals.

* Lateral vibration is detrimental to the integrity of traditional cutting structures, but Ulterra’s® proprietary CounterForce cutting structure redirects the lateral vibration back into the formation keeping the cutters sharper, longer.
