Product Description

Ofite_C

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 (casing, formation, sandstone, etc.) pressed against a rotating steel bob while immersed in a circulating cup of test fluid.


Features

• 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
• Software
• Operator inputs rotational speed, side load, and refresh period
• Test archive provides access to historical data
• Graphs rotational speed (RPM), torque (in-lb), side load (lb), and coefficient of friction with respect to time
