Water with Scaling Tendencies
Acid Max sticks are water soluble sticks containing a combination of acid, surfactant, dispersing agent, iron sequestrator, and inhibitor in solid stick form. Acid Max sticks are primarily used in water injection wells to remove carbonate scale and rust deposits and lower injection pressures. Injection pressure drops of several hundred PSI have been observed following acid stick treatments. Some wells have gone on vacuum and taken water by gravity. Acid Max sticks have some limited uses in oil wells, gas wells, and water supply wells.
