Abstract:

Disclosed is a process for preparing a foamer composition having an anionic surfactant and a neutralizing amine. The process includes the steps of estimating an extent to which the anionic surfactant will decompose into acidic components under an elevated temperature range, determining an effective amount of neutralizing amine needed to sufficiently neutralize the acidic components upon the decomposition of the anionic surfactant and mixing the effective amount of neutralizing amine with the anionic surfactant. Also disclosed is a foamer composition having from about 5% to about 70% by weight anionic surfactant, from about 1% to about 20% by weight neutralizing amine, from about 2% to about 10% by weight amine-based corrosion inhibitor, from about 0% to about 20% by weight solvent, from about 1% to about 10% by weight scale inhibitor and from about 0% to about 30% water.
