Product Description

PURELUBRI^® EP is a high temperature, extreme-pressure lubricant for use in all water-based drilling fluids. PURELUBRI^® EP is effective for reducing torque, drag and friction, preventing side-wall sticking, prolonging bit bearing life, and preventing corrosion. PURELUBRI^® EP reacts directly with metal surface by a chemisorption process, forming a continuous lubricating film on the BHA surface. This film forms a physical barrier that reduces metal-to-metal friction and pipe wear, and protects the metal surfaces against corrosion hydrogen embrittlement. PURELUBRI^® EP contains no hydrocarbons and no harmful to human health and environmental.

Applications/Functions

• Increases extreme-pressure lubricating properties of drilling fluids
• Reduces wear of metal parts
• Reduces torque problems in high angle, long horizontal and complicated drilling operations

Advantages

• Effective in small concentrations
