74 E&MJ • JUNE 2019 COMPANY PROFILE-PAID ADVERTISEMENT Varel Mining and Industrial: Drilling Expertise and Technology Varel Mining and Industrial designs, man- ufactures, and services application-spe- cific roller cone bits for the mining and construction industries. Proprietary design capabilities, efficient manufac- turing, and a global presence provide a unique ability to reliably and rapidly deploy industry-leading drilling solutions. Varel's leadership in roller cone bits and rotary percussion systems is driven by a commitment to innovative technolo- gy, advanced laboratory science, and decades of practical expertise focused on improving performance. Roller Cone Bits Varel roller cone bits provide a compre- hensive set of options for fine-tuning drilling performance in any rock and application. Each bit is a highly engi- neered product designed for the task, and easily enhanced with a wide range of spe- cialized features. These innovative, often patented, and always-reliable technolo- gies apply decades of experience to fully optimizing ROP, lowering total drilling cost, and extending bit life. That legacy and commitment is recognized in indus- try-leading bits, including Ridgeback ® , D-Force™, Avenger ® , and Target ® ; and pioneering features such as EdgeGuard ® shirttail protection and Sidewinder™ cut- tings removal enhancement. Rotary Percussion System Percussion forces in mining blast hole drilling applications are a powerful solu- tion for increasing ROP and lowering drilling costs. Varel's RPS tool and bits provide percussion versatility, reliability, and performance with innovative tech- nology that complements rotary forces. Patented RPS tools efficiently apply com- pressed air energy to extend the benefits of percussion options across a wide range of formation applications. The versatile tool mitigates water concerns and oper- ates in rotary-only mode as needed. RP bits build on in-depth Varel expertise to stand up to the demands of rotary percus- sion tools for reliable performance. Based on Ridgeback blast hole mining bits, the percussion bits feature reinforced welds, patented HET cutting structures, and enhanced structural strength. Technology At the heart of the Varel solution is a long-standing commitment to technology. Industry-leading innovation is the result of a proven process of understanding the challenge, engineering the solution, and applying it effectively and economically. Proprietary software solutions include the Advanced Modeling Package (AMP) for standalone modeling of cutting struc- ture interaction with the formation for practical, real-world design. The drilling simulator uses Geoscience and customer supplied lithology data, along with RC Pro cutting structure designs, to virtually approximate ROP and cutting structure life in different formations and drilling conditions. RC Pro software for cutting structure and bearing design facilitates rapid product development and design accuracy. Product performance is assured by extensive metallurgical laboratory test- ing performed in state-of-the-art facilities, and advanced seal testing to understand the effects of friction-related heat pro- duced at different motor speeds and axial motion frequencies. Equally important, Varel field service engineers provide expert analyses to fine tune applications and inform the development of new products. Commitment and Resources The industry was a much different place in 1947 when Varel began supplying drill bits for the mining industry. In the intervening years, it has been a lead- ing innovator of specialized technologies and products that apply a unique exper- tise to producing task-driven solutions. Today, Varel is a powerful resource for reliable options that increase ROP and lower drilling costs for mining and indus- trial applications.
