Abstract
Provided are compositions and methods that use a true crystallization temperature reduction additive in the aqueous internal phase. An example method may comprise providing an oil-based treatment fluid in the form of an invert emulsion comprising an aqueous internal phase and an oil external phase. The aqueous internal phase may include a bromide brine and a true crystallization temperature reduction additive, wherein the bromide brine has a density of about 14.2 lbs/gal or greater. The method may further include placing the oil-based treatment fluid into a wellbore.

A method comprising:
- providing an oil-based treatment fluid in the form of an invert emulsion comprising an aqueous internal phase and an oil external phase, wherein the aqueous internal phase comprises a bromide brine and a true crystallization temperature reduction additive, wherein the bromide brine has a density of about 14.2 lbs/gal or greater;
- and
- placing the oil-based treatment fluid into a wellbore.
An oil-based treatment fluid for use in subterranean operations, the oil-based treatment fluid comprising:
- an invert emulsion comprising an aqueous internal phase and an oil external phase, wherein the aqueous internal phase comprises a bromide brine and a true crystallization temperature reduction additive, wherein the bromide brine has a density of about 14.2 lbs/gal or greater;
- wherein the bromide brine has a first true crystallization temperature without inclusion of the true crystallization temperature reduction additive;
- and
- wherein the bromide brine has a second true crystallization temperature with the true crystallization temperature reduction additive that is lower than the first true crystallization temperature reduction additive.
