In Reeves County, operators are faced with the challenge of drilling through the Delaware Mountain Group, which includes drilling through the Bell, Cherry, and Brushy Canyon. The notoriously troublesome Brushy Canyon requires a bit that will be able to overcome interbedded lithological challenges while maintaining a steady ROP.

For drill bit engineers, knowledge truly is power. By analyzing everything from why bits fail to how cutters interact with different formation types, they are responding to the trend toward longer laterals with solutions that drill faster and stay in hole longer to reach total depth in fewer runs. The newest generation bit designs help achieve simultaneous improvements in rates of penetration and footage drilled through more effective hydraulics, fine-tuned cutting structures and novel cutter elements. These innovations could not have come at a better time. As average lateral lengths continue to rise, so has the demand for efficient drill bits. Longer laterals and increased drilling in North America helped the worldwide bit market grow 20 percent in 2018 to reach $3.3 billion, according to Spears & Associates.
Ulterra’s Health, Safety, Security, and Environmental (HSSE) team works hard to ensure a safe workplace for all employees. This is all made possible by managing business operations through an HSSE Management System that is consistently improving, as well as the “safety first” mindset that has been widely adopted by the Ulterra team. This year, Ulterra’s Leduc Manufacturing Facility reached four years with no recordable incidents.
Drilling with Bapetco, a joint venture between Shell and the Egyptian General Petroleum Cooperation, in Western Egypt involves drilling through multiple formations in the 12.25” and 8.5’’ sections. Starting off with chalky limestone in the Apolonia and Khoman formations in the 12.25” section, then interbedded formation in Abu Rawash Members (shale, limestone, and sandstone), and finishing the hole in the Bahareya in a sandstone formation in the 8.5’’ section. Typically, in this area, it takes at least one bit per section on a motor or RSS assembly to complete the well.
The Brushy Canyon is a well-known troublesome formation in Southeastern New Mexico that consists mainly of sandstone but contains some limestone lenses and thin beds of shale and chert. The inconsistency of drilling in this “ratty” formation leads to many drilling problems. The formation top is typically located at 7,000-8,000 ft. TVD and has a thickness of about 1,000 ft.
Benny the Bit is a 2018 children’s picture book created in-house at Ulterra. Originally released and created for Ulterra’s Family Fun Day, Benny the Bit helps illustrate the journey of a drill bit, Ulterra’s manufacturing process, and the secret power of teal. The creation of this book was driven by the desire to teach our employees’ young kids about what their parents do here at Ulterra and to create a bigger picture of the oil and gas industry that they can easily understand.

Ulterra is proud to announce that Hart Energy’s distinguished panel of judges have chosen SplitBlade™ as one of the winning technologies for the 2019 E&P Special Meritorious Awards for Engineering Innovation (MEA). The MEA recognizes new technologies that reflect excellence in innovation and practicality while having the potential to improve efficiency, safety, and profitability. MEA entries are judged based on the impact they have, both technically and economically, on changing and developing the energy industry.
Ulterra’s general counsel joined the company right before its acquisition by Blackstone and threw himself into the hard work necessary to learn the company’s ins and outs
Oilfield Technology invited experts from BHGE, ULTERRA, and VAREL to share their knowledge on a variety of drill bit design topics. Ulterra weighed in to share their expertise on a variety of topics.
Air drilling technology is considered to be a cost-effective drilling method for operators – requiring minimal cleanup and disposal of fluid on the surface. Another huge benefit of air drilling is that it’s faster, but operators usually only drill the first 30-40 degrees of the curve on air.
