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