Abstract
Polysaccharides may be partially oxidized by oxidative opening of a monosaccharide unit while still retaining glycosidic bonds. Such polysaccharides may be further functionalized with an amine moiety at a site of oxidative opening. Polysaccharides that are partially oxidized and amine-functionalized in this manner may be combined with an aqueous liquid to form compositions suitable for stabilizing clays in clay-containing formations. Clay stabilization may promote reduced swelling of the clays in the presence of water.
