By a News Reporter-Staff News Editor at Journal of Engineering -- Fresh data on Chemical Engineering are presented in a new report. According to news originating from Morgantown, West Virginia, by VerticalNews correspondents, research stated, "Invert emulsions are used to drill for oil and gas when good wellbore stability and high temperature tolerance are required. These drilling fluids contain a solid phase and two immiscible liquid phases stabilised with a polymeric surfactant."
Our news journalists obtained a quote from the research from West Virginia University, "In ultra deep drilling, due to high temperature, the surfactant degrades causing phase separation. However, fine particles can be used as stabilisers, and the result is a Pickering emulsion. Here, we demonstrate that the use of a combination of hydrophobic nanoparticles and organically modified nanoclay results in stable water-in-oil invert emulsions model drilling fluids. These gel-like model fluids have the desired plastic viscosity and yield stress suitable for drilling fluid applications that can be modified by adjusting the nanoparticle-content."
According to the news editors, the research concluded: "Aging experiments at 225 degrees C showed that they also have high-temperature stability for demanding drilling operations."
