Non-ionic solvent blend that shifts rock to water-wet, breaks/stabilizes emulsions, and speeds cleanup/flowback after acid. Solubilizes organic residues (asphaltenes, sludge, polymers) and improves acid compatibility in sandstone/limestone. Mitigates water blocks in tight zones; lowers IFT and helps fines dispersion.
Film-forming cationic packages (quats/imidazolines) protect tubulars and iron during HCl/organic/mud acid treatments. Works in 5–28% HCl and gelled/crosslinked acids; add intensifier (e.g., formic/formamide/KI) above ~300–350 °F or with high Fe³⁺.
