Crude oil contains asphaltenes, colloid, and paraffin, which will react with acid and precipitate from crude oil. The formed sediment may plug formation and affect acidification.  In 1970s, alkylphenyl fatty acid and certain amount of oil-soluble surfactant were used as sediment cleaning agent worldwide.  Later on it was replaced by sulfonate or petroleum sulfonate.  In 1990s in China a solvent was found to function as a sediment cleaning agent but not as effective as W53 from US. By taking advantage of the special characters of both, we put phenyl sulfonate and polyether in solvent.  This blend improves the efficiency of precipitate prevention and sediment removal.
