Summary
OBF-LUBE HP is specifically designed to decrease the coefficient of friction in all water-base drilling fluids, which lowers torque and drag in the wellbore. With a unique wettability characteristic which lowers the potential for Bottom-Hole Assembly (BHA) balling, OBF-LUBE HP contains no hydrocarbons and is compatible with all water-base fluids, including mono-/divalent brine fluids. With minimal contribution to the rheological properties of mud systems, OBF-LUBE HP does not foam and can be added to the mud system through the mixing hopper or directly to the surface system wherever good agitation is available.
Advantages
l Effective, all-purpose lubricant for water-base mud systems
l Decrease the coefficient of friction which reduces torque and drag
l Does not increase rheology or gel strengths
l Contains unique metal-wetting additives which reduce the tendency of soft, sticky shale to cause bit and BHA balling
l Does not cause foaming
l Biodegradable with no hydrocarbons
Usage range
Recommend temperature: ≤200℃ (BHCT).
Recommend dosage:1.0~3.0% (BWOC).
