Abstract

A quaternary amine composition selected from the group consisting of Formula I, Formula II, Formula III, and combinations of the same. A method of synthesizing a quaternary amine composition comprising the steps of reacting an alkoxylated dimer diamine with a methyl halogen, where the methyl halogen is selected from the group consisting of methyl chloride, methyl iodine, and combinations of the same; and allowing the reaction to proceed to produce the quaternary amine composition, the quaternary amine composition selected from the group consisting of Formula I, Formula II, Formula III, and combinations of the same. A method of treating a well comprising the steps of introducing an additive-containing well fluid to a well, where the additive-containing well fluid comprises a quaternary amine composition and a well fluid, allowing the additive-containing well fluid to interact with the well, and treating the well with the additive-containing fluid.
