LUBE BX Field Brine Lubricant | SLB


Field brine lubricant

Schlumberger Oilfield Services

LUBE BX field brine lubricant is a cost-effective, high-performance lubricant designed to reduce the metal-to-metal and metal-to-rock coefficient of friction in produced water and brine fluids. It decreases torque and drag, thus increasing ROP in water-based drilling fluid, produced water, or brine in highly deviated and horizontal drilling applications.

It is generally recommended to add LUBE BX lubricant at 3% by volume, but specific drilling conditions will dictate a suitable concentration. LUBE BX can be incorporated into the mud system through the mud hopper using no special or additional mixing equipment.

Toxicity and handling

Bioassay information is available upon request. Handle as an industrial chemical, wearing protective equipment, and observing the precautions as described in the safety data sheet.

Packaging and storage

LUBE BX lubricant is generally packaged in 55-galUS [208-L] drums. Follow safe warehousing practices regarding palletizing, banding, shrink-wrapping, or stacking. Keep containers tightly closed in a dry, cool, and well-ventilated place. Store in original container. Avoid heat, flames, and other sources of ignition.
