Title: Nathalie Monfreux-Gaillard: Innovator in Reversible Emulsions
Introduction
Nathalie Monfreux-Gaillard is a prominent inventor based in Paris, France. She has made significant contributions to the field of reversible emulsions, particularly in the context of oil drilling fluids. With a total of 3 patents to her name, her work has garnered attention for its innovative approach to stabilizing emulsions.
Latest Patents
Nathalie's latest patents focus on reversible emulsions stabilized by amphiphilic polymers. The first patent details modified hydrophobic polyelectrolytes created through amide formation of a hydrophilic skeleton using n-alkylamines, where the alkyl chain consists of 6 to 22 carbon atoms. The preferred method involves di-n-dodecylamine, with the hydrophilic skeleton being a sodium polyacrylate or polyacrylic acid that corresponds to a statistical acrylate-AMPS copolymer. These polymers are particularly useful for stabilizing direct or invert emulsions that may be destabilized or inverted due to changes in the salinity of the aqueous phase or pH modifications. This invention is especially beneficial for stabilizing oil drilling fluids, including those used in drilling, fracturation, acidification, or completion processes.
The second patent reiterates similar concepts, emphasizing the application of these reversible emulsions in drilling fluids. The innovative approach to modifying hydrophobic polyelectrolytes has the potential to enhance the efficiency and stability of drilling operations.
