Total Hardness – Water Based Mud Testing

Total Hardness – Water Based Mud Testing

The total hardness test gives an indication of the level of soluble Calcium and Magnesium ions present in the mud.

Such ions are considered detrimental since, under conditions of high pH (>11.5), they may render polymer, treatments for viscosity and fluid loss less effective.

High levels of hardness will also flocculate Bentonite.

The total hardness should be controlled below 400 mg/L and must not be allowed to rise above 600 mg/L.
