    • A concentrate which forms an acid internal microemulsion well treatment composition when added to an acid treatment fluid. The concentrate comprises in the range of from about 20% to about 98% by weight of a hydrocarbon carrier fluid, in the range of from about 1% to about 50% by weight of an alkyl alcohol having from 4 to 18 carbon atoms and in the range of from about 1% to about 50% by weight of an emulsifying agent comprising at least one compound selected from the group consisting of sulfate esters, phosphate esters, alkyl aromatic sulfonic acids, amine salts having ester or amide linkages, quaternary ammonium compounds having ester of amide linkages, propoxylated fatty acids, and propoxylated alcohols. Also disclosed are an acid internal microemulsion well treatment composition and a method of treating a subterranean formation to increase the production of hydrocarbons therefrom.
