1. A ready-to-use surface treatment composition for increasing the permeability of a hydrocarbon shale formation during stimulation, the composition comprising:
a passivator comprising at least one of a quaternary monosaccharide having from about 1 to 3 moles of quaternary functional groups, and a quaternary saccharide having a number of the monosaccharide molecules ranging from about 2 to 20 bonded together by glycosidic linkage with from 0.5 to 3 moles of quaternary functional groups per molecule of the monosaccharide;
a conditioner comprising at least one of a surfactant, a hydrotrope, and a terpene; and
a solvent,
wherein the weight percent ratio of the passivator and the conditioner ranges between 20:1 to 1:20 respectively.
