High density brines |
| abstract |
A method of treating a wellbore comprises injecting into the wellbore a high density brine comprising water; an inorganic salt; and a polyol having at least four hydroxyl groups per molecule, the polyol being present in an amount effective to cause the high density brine to have a density of about 14.2 pounds per gallon to about 22 pounds per gallon; and to suppress the true crystallization point of the brine to about -70°F to about 70°F at a pressure of about 0 to about 20000 psi determined according to API 13 J. |
