Halliburton releases new drill bit tech proven in Williston Basin
Halliburton has released a new drill bit technology proven in the field by a major Williston Basin operator. The trademarked Cruzer bit, features rolling diamond pieces on the face of the bit which increases tool face control without reducing efficiency downhole. The system allows operators to increase the rate at which the bit penetrates a formation at a lower cost per foot, according to Halliburton.
To cite the effectiveness of the drill bit technology, Halliburton used a field case study from the Williston Basin. In 14 hours, an operator was able to drill a horizontal well’s curve—the fastest run of any offset well in the area due to the reduced wear on the bit. “It was a huge success in trying to use Cruzer,” said Brad Dunbar, product manager for Drill Bits at Halliburton.
Dunbar said Halliburton designed the Cruzer after looking into ways to control the depth of the cut, or how the drill bit is able to engage the formation at a constant rate without taking energy away from the cutting structure. Small diamond rolling features on the face of the bit lower the coefficient of friction that happens during the drilling process, and, the rolling pieces can be replaced or repaired for future runs. The system is designed to house the rolling features so that they do not get lost or come out downhole. The system is also cable of drilling the most challenging formations due to its abrasion resistance, impact resistance and thermal mechanical integrity.
Steve Allen, vice president of Drill Bits and Services, said the Cruzer offers another innovative product to its clients. The system was designed through Halliburton’s Design at the Customer Interface process. DACTI customizes each bit for a customer’s specific application.
