Abstract
The present invention includes compositions and methods for treating a hydrocarbon-bearing formation by contacting the hydrocarbon-bearing formation with a fluid that includes at least one of a polyol or polyol ether, wherein the polyol and polyol ether independently have from 2 to 25 carbon atoms; and at least one of a monohydroxy alcohol, ether, or ketone, wherein the monohydroxy alcohol, ether, and ketone independently have from 1 to 4 carbon atoms, and wherein the at least one of a polyol or polyol ether is present in the fluid at at least 50 weight percent, based on the total weight of the fluid.
