TM0374-2007 Laboratory Screening Tests to Determine the Ability of Scale Inhibitors to Prevent the Precipitation of Calcium Sulfate and Calcium Carbonate from Solution (for Oil & Gas Prod. Systems)
Provides 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. Describes static laboratory screening tests designed to give a measure of the ability of inhibitors to prevent the precipitation of calcium carbonate and calcium sulfate from solution at 71°C (160°F). The test methods are recommended only for ranking the performance of different chemicals under laboratory conditions set by these methods. They are not intended to provide actual field treating rates. Keywords: calcium carbonates, calcium sulfates, scale inhibitors, screening testing.
