Abstract: Methods may include quantifying the concentration of residual free amine and/or free carboxylic acid in a product mixture prepared from a reaction of a multireactive species and a fatty reagent; verifying that the concentration for the free amine and/or free acid in the product mixture is within an acceptable threshold for a given application; and combining the product mixture with one or more wellbore fluid components to generate the wellbore fluid. In another aspect, methods may include including reacting the multireactive species and a fatty reactant to generate a product mixture; quantifying the concentration of residual free amine and/or free carboxylic acid in the product mixture; verifying that the concentration for the free amine and/or free acid in the product mixture is within an acceptable threshold for a given application; and collecting the product mixture.

Abstract: Wellbore fluids and methods of drilling with the wellbore fluids are provided. One wellbore fluid may include an oleaginous continuous phase, a non-oleaginous discontinuous phase, and a polymer having a polycyclic backbone. One method may include pumping the wellbore fluid into a wellbore through an earthen formation.

Abstract: Compositions may contain an oleaginous base fluid, and a branched amidoamine surfactant prepared from the reaction of an alkylene amine or an oligoalkylene amine and a branched acid having a C4 to C24 primary hydrocarbon chain, and having one or more C1 to C24 branches. Methods may include emplacing a wellbore fluid into a wellbore, wherein the wellbore fluid contains an oleaginous base fluid; and a branched amidoamine surfactant prepared from the reaction of an alkylene amine or an oligoalkylene amine and a branched acid having a C4 to C24 primary hydrocarbon chain, and having one or more C1 to C24 branches.

Abstract: Wellbore fluids may include an oleaginous continuous phase; a non-oleaginous discontinuous phase; and an emulsifier stabilizing the non-oleaginous discontinuous phase in the oleaginous continuous phase, wherein the emulsifier is the product of a reaction between an alkyl cyclic anhydride and a polar reactant, wherein the polar reactant is one or more selected from a group containing alkyl amine, alkanolamine, and polyamine. Methods may include drilling a wellbore with an oil-based mud, wherein the oil-based mud is an invert emulsion containing an emulsifier stabilizing the invert emulsion, wherein the emulsifier is the product of a reaction between an alkyl cyclic anhydride and a polar reactant, wherein the polar reactant is one or more selected from the group of alkyl amine, alkanolamine, and polyamine.
