Lubricity Evaluation Monitor

Lubricity Evaluation Monitor

The Lubricity Evaluation Monitor (LEM) is a laboratory device designed to evaluate lubricants by direct comparison. It determines the coefficient of friction between an interchangeable wellbore sample pressed against a rotating steel bob while immersed in a circulating cup of test fluid.

Features of Lubricity Evaluation Monitor

• Pneumatic ram applies side load pushing the bob against the sample
• Periodic refresh of test fluid by pulling bob away from sample at definable intervals
• Clamp allows samples of casing, formation, sandstone, etc. to be tested in the same fixture
• Computerized data acquisition and control
