Abstract
A stabilized composition for use as a well fluid is provided. The stabilized composition includes a brine, a polyol, the polyol in an amount operable to inhibit solid formation, the polyol further operable to dissolve within the brine; and a stabilization compound, the stabilization compound operable to stabilize the polyol, such that the polyol does not degrade at a bottom hole temperature.
