Rick Motes, Marc Lopeman, and Thomas Rose from Terelion recently held Rotary Percussion System™ (RPS) training — because performance starts with knowledge.

The RPS Gen 3 enhances drilling performance by delivering high-frequency percussive energy through the drill string while maintaining rotary motion. This combination increases Rate of Pe*******on (ROP), reduces time on bottom, and improves overall efficiency in hard rock and demanding applications.
