Anti-sludging agent can remedy sludging problems encountered in hydrochloric acid (HCl) solutions when raw acid contacts certain crude oils. Features anti-sludging agent helps prevent acid sludge formation either by acting as a chemical barrier between the asphaltene particles and acid or by reacting with and solubilizing sludge. It is used in low concentrations (no higher than 1.0%) in most acid stimulation treatments, and it allows more effective, higher concentrations of acid to be used in treatments (from 15 to 28%). In addition to preventing sludge formation, it can also perform as a nonemulsifier to prevent some acid-oil emulsions and improve the performance of other nonemulsifiers.
