Overview
The Scale Dissolver Series is specifically designed for complex inorganic scale problems in oilfield production systems, particularly for hard-to-remove sulfate scales such as barium sulfate (BaSO₄) and strontium sulfate (SrSO₄).
The product utilizes a synergistic mechanism of chelation, complexation, and crystal lattice disruption to effectively dissolve existing scale deposits while preventing further growth and re-deposition. It is widely used in surface gathering systems, water injection systems, and downhole treatments as a key chemical solution for system restoration and maintenance.
