Abstract
Methods to separate or recover brine that is present in an invert emulsion are described. The brine is present as an internal phase in the invert emulsion. The brine can be a valuable component, such as an alkali metal formate, and separation and recovering of the brine from the invert emulsion permits the brine to be reused.
