Laboratory Screening Tests to Determine the Ability of Scale Inhibitors to Prevent the Precipitation of Calcium Sulfate and Calcium Carbonate from Solution (for Oil and Gas Production Systems)

The test methods in this standard are designed to provide a relative and quantitative measure of the abilities of scale inhibitors to prevent the precipitation of solids, a necessary and critical stage in the formation of scale. The test methods described in this standard are static laboratory screening tests designed to give a measure of the ability of scale inhibitors to prevent the precipitation of calcium sulfate and calcium carbonate from solution at 71°C (160°F). This standard was maintained by Task Group 493.
