ORGANOCLAY-FREE INVERT EMULSION OIL-BASED DRILLING FLUIDS WITH POLYHEDRAL OLIGOMERIC SILSESQUIOXANE - A simplified explanation of the abstract
This abstract first appeared for US patent application 17827273 titled 'ORGANOCLAY-FREE INVERT EMULSION OIL-BASED DRILLING FLUIDS WITH POLYHEDRAL OLIGOMERIC SILSESQUIOXANE
Simplified Explanation
- The patent application is for a composition of an oil-based drilling fluid formulation used in drilling wells. - The composition includes an invert emulsion of an oil phase and an aqueous phase. - The oil phase contains an oleaginous fluid and a liquid viscosifier called polyhedral oligomeric silsesquioxane (POSS). - The method involves introducing this drilling fluid formulation downhole through the wellbore. - The goal is to maintain stable rheological properties of the drilling fluid, such as viscosity, yield point, plastic viscosity, gel strength, and electrical stability. - These stable properties should be maintained for a period of up to about 96 hours.
Original Abstract Submitted
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.
