The ULTRAFREE additive is specifically designed to improve the rate of penetration (ROP) in theM‐I SWACO high‐performance ULTRADRIL water‐base mud system, especially when run with polycrystalline diamond compact (PDC) bits. ULTRAFREEROP enhancer employs a special blend of surface‐active agents to keep the bit free of solids. The chemical makeup of the ULTRAFREE additive assists in removing any buildup of drill solids below the bit, allowing the cutters to make continuous contact with new formation. ULTRAFREE ROP enhancer not only reduces bit and/or bottomhole assembly (BHA) balling, but also lowers torque and drag.
