Ulterra is proud of its innovative culture and takes pride in delivering unconventional solutions. Ulterra’s “Design Engineering Software” tool box provides Product Engineers the capability to quickly and effectively develop optimized drill bit designs per specific performance objectives. Proprietary design modeling and analytical capabilities have been developed to facilitate geometry creation and analysis of the cutter-rock interaction without limiting innovation of new ideas.
Modeling of the interaction between bit and formation is critical to ensure that product demands are met. The bits durability, ROP response, reactive torque, directional characteristics, and stability are all key factors considered through the design process. Ulterra employs precise geometric modeling to calculate the engagement of cutters, load limiting inserts, blades etc. with the formation. This is based on a precise 3D CAD model and the precise engagement of each and every element can be measured under specific operating parameters.
One of the most vital aspects of drilling is the hydraulic system. Good hydraulics improves bit performance by effectively and efficiently evacuating cuttings and cooling the cutters. The effects of proper hydraulics include:
Although the drill bit is only one small piece of the entire hydraulic system, it is critical to efficient drilling.
