Linear Swell Meter

The Fann Linear Swell Meter Model 2100 (LSM) helps determine shale hydration or dehydration by measuring the increase or decrease in length over time of reconstituted or intact shale core. Together the LSM and Capillary Suction Time (CST) tests determine the recommended mud system for drilling through a specific shale formation. First, a CST test is conducted to determine the correct inhibitor for the shale. Then, a variety of fluids are tested.

Test results are graphed to show the percent of swelling versus swelling time in minutes. The LSM test demonstrates the inhibitive effects of these various fluids on shale swelling.
