Fighting Scale—Removal and Prevention - Schlumberger

When scale forms, a fast, effective removal tech-nique is needed. Scale-removal methods involve both chemical and mechanical approaches, each with its own niche—depending on the location of the scale and its physical properties. Some mineral scales, such as calcium carbon-ate [CaCO 3], can be dissolved with acids, while most others cannot.
