Abstract
A composition useful as a well lubricant, solvent and emulsifier that is preferably formed by the reaction and distillation of a tall oil fatty acid with a fatty alkanolamide, preferably in the presence of methyl ester of fatty acids, and most preferably when further reacted and distilled with an emulsifier such as coconut oil diethanolamide or distilled tall oil amide of AEP. The fatty acids and oils useful in the invention can range from C.sub.8 to C.sub.24, with C.sub.12, C.sub.14, C.sub.16, C.sub.18 and C.sub.20 fatty acids and oils being most preferred. The presence of methyl ester is preferred because it functions as a foam supressant, diluent and amine scavenger during distillation.
