ASA-2 is an anionic anti-sludge additive with strong water wetting capabilities on sandstone formations. It is often incorporated into acid mixtures as an anti-sludge additive and de-emulsifier. ASA-2 has the unique ability to provide stable mixtures with organic solvents.
ASA-30 is an acidizing additive that imparts anti-sludge and de-emulsification properties to hydrochloric acid. It is used in acid treatments where emulsion or sludge formation may occur as a result of unstable asphaltenes in the oil and is particularly effective in dark crudes with high API gravity. The emulsion breaking properties of ASA-30 allow it to prevent acid induced emulsions, as well as break existing downhole emulsions.
ASA-5 is an anionic surfactant acidizing additive that imparts antisludge and de-emulsification properties to hydrochloric acid. It is used in treatments where emulsions or sludges could form as a result of unstable asphaltenes in oil.
