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