1. A method for increasing the permeability of a hydrocarbon shale formation during stimulation, the method comprising:
contacting surfaces of a hydrocarbon shale formation with an effective amount of a surface treatment composition, 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 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 in the saccharide;
a conditioner comprising at least one of a surfactant, a hydrotrope, and a terpene; and
water;
the weight percent ratio of passivator and conditioner ranges between 20:1 to 1:20 respectively;
allowing the surface treatment composition to condition and passivate the surfaces to form passivated surfaces;
water contacting the passivated surfaces acquires a water-wet angle of contact; and
wherein the passivator destabilizes the interface between the water and the passivated surfaces causing the water to spread across the passivated surfaces further decreasing the angle of contact.
