Project case in Brazil

Brazil is one of the world's largest producers of manganese ore. In the state of Minas Gerais, on-site personnel are conducting core drilling operations to study the quality and exploration potential of manganese ore. However, during the actual coring process, the field workers encountered significant difficulties with the rock formation. They noticed that the drill bits were wearing out rapidly, the drilling speed was slow, and at times, the drill bits even got stuck. This posed a practical challenge to the coring operation, and the drill bits were on the verge of depletion. The workers realized that conventional drill bits were inadequate for completing the coring work, and the project came to a standstill.

Through the recommendation of colleagues engaged in manganese ore coring operations in the state of Mato Grosso do Sul, the on-site personnel were introduced to Best’s drill bits. With remote guidance from Best engineers, they made further adjustments to the drilling parameters, including the speed, downforce, and flushing fluid flow, in order to overcome the hardness of the rock formation. Throughout the process, the workers observed that the wear and tear on the drill bits decreased by at least 50% compared to the previously used ones. The detailed consumption of drill bits was reduced, and the challenges posed by the increased resistance from the hard rock formation were successfully overcome. As a result, the project operations were completed smoothly, and the durability and stability of Best’s drill bits, along with the professional service provided by their engineers, were highly recognized by the on-site personnel.
