Extreme Pressure(EP) Lubricity Tester – Model 212

Extreme Pressure (EP) Lubricity Tester – Model 212

The Fann Model 212 EP/Lubricity Tester is a robust, dual-function instrument designed to measure both the lubricating quality of drilling fluids and their extreme pressure (EP) performance. By simulating downhole torque and drag conditions, it provides valuable insight into the friction-reducing properties of drilling muds and the effectiveness of lubricating additives. This device is essential for optimizing drilling performance, reducing wear on mechanical parts, and evaluating additive performance in complex fluid systems.

Built for high-accuracy simulation of both steel-on-steel contact under pressure and high-load rotational motion, the Model 212 allows operators to assess film strength and predict mechanical wear—critical for bit-bearing longevity and drill pipe mobility.

Key Features of Extreme Pressure (EP) Lubricity Tester – Model 212

• Dual Testing Capability: Performs both EP (Extreme Pressure) and standard lubricity (torque/drag) tests.

• Realistic Downhole Simulation: Models friction at contact points between drill pipe and borehole under realistic loads (5,000–100,000 psig).

• Direct Torque Readout: Torque arm dial provides direct measurement of inch-pound resistance during lubricity tests.

• Steel Ring & Block Setup: Standardized steel-on-steel interface to assess lubricant film performance and breakdown.

• Evaluate Additives: Helps determine type and quantity of lubricant additives required to enhance fluid performance.

• Wear Rate Prediction: Identifies wear characteristics of fluids on mechanical components.

• Durable Construction: Built for long-term use in lab environments handling high-stress testing.

Applications of Extreme Pressure (EP) Lubricity Tester – Model 212

• Drilling Fluid Development: Evaluate the lubricity of water-based and oil-based muds.

• Additive Screening: Measure performance of EP and lubricity additives.

• Bit-Bearing Protection: Predict bearing life under high pressure, high temperature (HPHT) conditions.

• Torque & Drag Analysis: Simulate downhole conditions to improve rig efficiency and prevent string sticking.

• Routine Fluid Monitoring: Used in field or lab settings to ensure lubricity performance stays within required parameters.
