CorFix™ ACI-200 Acid Corrosion Inhibitor
CorFix™ ACI-200 with a base of quaternary ammonium compound is a high temperature, high performance acid corrosion inhibitor, used in matrix acidizing and acid fracturing operations. It is applicable in challenging conditions in the environments consisting severe and corrosive brines. CorFix™ ACI-200 as an acid corrosion inhibitor is compatible with intensifiers and various solvents. Its performance was evaluated in varying HCl and intensifier concentrations and efficiency assessed according to the changes on the corrosion rate and pits of the coupons.
