Claim 9:
10. A method of formulating a wellbore fluid, the method comprising:
quantifying, by nonaqueous titration, the concentration of residual free amine in a product mixture prepared from a reaction of a multireactive species and a fatty reactant, wherein the reaction of a multireactive species and a fatty reactant comprises an amide- or imine-forming reaction;
verifying that the concentration for the residual free amine in the product mixture is within an acceptable threshold; and
combining the product mixture with one or more wellbore fluid components to generate the wellbore fluid;
further comprising determining the concentration of free carboxylic acid in the product mixture, and adjusting the concentration of the free carboxylic acid in the wellbore to a concentration within the range of 0 ppb to 10 ppb.
