Abstract
An oil-based treatment fluid for use in subterranean operations may comprise an invert emulsion including an aqueous internal phase and an oil external phase. The aqueous internal phase is solids free and comprises a two-salt brine and a true crystallization temperature reduction additive. The two-salt brine comprises a bromide and a nitrate, wherein the bromide brine has a density of about 14.2 lbs/gal to about 17 lbs/gal. There are no additional salts in the aqueous internal phase; The bromide brine has a first true crystallization temperature without inclusion of a true crystallization temperature reduction additive and a second true crystallization temperature with a true crystallization temperature reduction additive that is lower than the first true crystallization temperature reduction additive.
