Abstract
Improved aqueous fracturing fluids are disclosed that are particularly useful as well stimulation fluids to fracture tight (i.e., low permeability) subterranean formations. Gas wells treated with these fracturing fluids have rapid cleanup and enhanced well production. The fluids contain small but sufficient amounts of certain amine oxides to aid in the removal of the fracturing fluid from the formation. By facilitating the removal of fluid from the invaded zones, the amount of damage to the fracture faces in the formation is thereby minimized. The amine oxides correspond to the formula I, wherein Ris an aliphatic group of from 6 to about 20 carbon atoms, and wherein Rand Rare each independently alkyl of from 1 to about 4 carbon atoms. The amine oxides in which Ris an alkyl group are preferred, and those in which Ris an alkyl group of from 8 to 10 carbon atoms and Rand Rare each methyl or ethyl groups are most preferred.
