Abstract:
Compounds are identified that act as crystallization suppressants when added to clear brine fluids, significantly lowering the true crystallization temperatures of the brines, and allowing for higher salt content in clear brine fluids. The crystallization suppressants of the invention also allow for the preparation of higher density zinc free brines. Crystallization suppressant blends are also identified that allow for the preparation of high density clear brine fluids with lower viscosities.

Claim (Index 1):
A method for lowering the true crystallization temperature of a clear brine fluid comprising a halide salt and water and having a density of 10 ppg or more, which method comprises adding from 2 to 20 wt %, based on the combined weight of the halide salt and water, of a crystallization suppressant blend comprising a mixture of\n two or more of an aldose or ketose having at least 4 carbon atoms and/or an alditol having at least 3 carbon atoms; or a mixture comprising at least one aldose or ketose having at least 4 carbon atoms or an alditol having at least 3 carbon atoms with an amine, amino acid, alcohol or polyol other than an aldose, ketose having or an alditol, to provide a clear brine fluid with a true crystallization temperature of less than 20\u00b0 F. and a viscosity at 40\u00b0 F., measured as Brookfield viscosity using a #18 spindle at 60 rpm, of 250 cps or less.
