ORGANOCLAY-FREE INVERT EMULSION OIL-BASED DRILLING FLUIDS WITH POLYHEDRAL OLIGOMERIC SILSESQUIOXANE

A composition of an invert emulsion oil-based drilling fluid formulation includes an invert emulsion of an oil phase and an aqueous phase. The oil phase includes an oleaginous fluid and a liquid viscosifier that is a polyhedral oligomeric silsesquioxane (POSS). A method includes introducing an inver...

More Information
Summary:A composition of an invert emulsion oil-based drilling fluid formulation includes an invert emulsion of an oil phase and an aqueous phase. The oil phase includes an oleaginous fluid and a liquid viscosifier that is a polyhedral oligomeric silsesquioxane (POSS). A method includes introducing an invert emulsion oil-based drilling fluid formulation including an oil phase, an aqueous phase, and a liquid viscosifier including POSS downhole through the wellbore and maintaining wellbore conditions such that the invert emulsion oil-based drilling fluid formulation provides a stable rheological property including one or more of viscosity, yield point, plastic viscosity, gel strength, and electrical stability for a period up to about 96 hours.
