Polycrystalline-Diamond-Compact Bit

Ulterra has introduced its line of FastBack high-rate-of-penetration polycrystalline-diamond-compact (PDC) bits. FastBack-designed bits use a unique blade configuration that supports the cutters with a smaller-than-usual profile that eliminates wasted energy needed for pushing larger blades, thereby focusing all energy on the diamond cutting surfaces. This efficiency improvement resulted in a 56.8% drilling-speed increase in a Marcellus well. The FastBack’s new blade design is made possible by advanced surface coatings, which provide maximum erosion control without sacrificing strength. Additionally, the FastBack’s smaller blade configuration opens up the junk-slot area for optimal hydraulics and enhanced cuttings evacuation.
