Abstract: Metal contaminants may be problematic in a number of industries, particularly in the mining industry. Fines production and dust control may be similarly problematic in many industries, including the mining industry. Reaction products formed from a saccharide polymer and diallyldimethylammonium chloride (DADMAC) under room temperature to heating conditions in the presence of a hydroxide base or a radical initiator may be effective for promoting removal of metal contaminants from clay-containing substances, such as through froth flotation. The reaction products may also be effective for mitigating fines production and providing dust control by forming a coating upon a plurality of particulates.

Abstract: Compositions comprising a neutral surfactant or a reaction product thereof and a reaction product of a saccharide polymer and a fatty acid may be obtained in the presence of water and a hydroxide base (optionally in the presence of the neutral surfactant), the saccharide polymer comprising a dextran, a dextrin compound, or any combination thereof. The reaction product of the saccharide polymer and the fatty acid may be present at a concentration effective to lower surface tension of the neutral surfactant. Depending on the fatty acid identity, among other factors, the compositions may promote emulsification or de-emulsification. In addition, the compositions may promote foam formation under appropriate conditions. Treatment fluids comprising the compositions, including foamed treatment fluids, may be introduced into a subterranean formation to perform a treatment operation in which fluid emulsification or de-emulsification may occur.

Abstract: An agricultural product may comprise an aqueous carrier phase, a neutral surfactant or a reaction product thereof, and a reaction product of a saccharide polymer and a fatty acid. The reaction product of the saccharide polymer may be obtained in the presence of water and a hydroxide base (optionally in the presence of the neutral surfactant). The saccharide polymer comprises a dextran, a dextrin compound, or any combination thereof. The reaction product of the saccharide polymer and the fatty acid may be present at a concentration effective to lower surface tension of the neutral surfactant and may be highly biodegradable as evaluated by OECD 301B. Compositions comprising the reaction product of the saccharide polymer and the fatty acid may be applied to an untreated soil to form a treated soil that absorbs water faster or to a greater extent than does the untreated soil.

Abstract: A carrier phase, a neutral surfactant or a reaction product thereof, and a reaction product of a saccharide polymer and a fatty acid or a fatty ester may be formulated as consumer or industrial products of various types.

Illustrative products may include adjuvants, foaming agents, hard surface cleaners, skin creams and lotions, body washes, shampoos, liquid soaps, sunscreens, hair sprays and gels, cosmetics, deodorants, and antiperspirants.

Abstract: Proppant embedment can sometimes be problematic during fracturing operations. A partially oxidized, amine-functionalized polysaccharide comprising a plurality of oxidatively opened monosaccharide units and bearing an amine moiety at one or more sites of oxidative opening may lessen the amount of proppant embedment that occurs. Fracturing methods may comprise providing a fracturing fluid comprising such a partially oxidized, amine-functionalized polysaccharide and a plurality of proppant particulates, introducing the fracturing fluid into a subterranean formation at a hydraulic pressure sufficient to create or extend one or more fractures therein, such that at least a portion of the plurality of proppant particulates become localized in the one or more fractures, and releasing the hydraulic pressure. Upon releasing the hydraulic pressure, embedment of the proppant particulates in a face of the one or more fractures is about 10% to about 40% of a grain size of the proppant particulates.

Abstract: Loose particulate materials can be problematic in various aspects. For example, loose particulate materials may generate dust or be difficult to consolidate together. Fines in loose particulate materials may also be an issue. Coated particulates may alleviate some of the foregoing issues. Suitable coated particulates may comprise a particulate material comprising sand or a ceramic, and a polysaccharide composition coated upon the particulate material, the polysaccharide composition comprising a functionalized polysaccharide. Other particulate materials such as wood chips and animal litter particulates may be coated with functionalized polysaccharides to achieve similar advantages.

Abstract: Interactions between aqueous fluids and clay-containing subterranean formations may be problematic due to issues associated with clay destabilization and migration. Functionalized dextrin compounds that are partially oxidized and bear at least one amine group at an oxidation site may promote clay stabilization for more effective treatment of a subterranean formation. Subterranean treatment methods may comprise: providing a clay stabilizing composition comprising an amine-functionalized dextrin compound, the amine-functionalized dextrin compound comprising 2 to about 20 glucose units linked together with ?(1,4) glycosidic bonds, and a portion of the glucose units being oxidatively opened and functionalized with at least one amine group at a site of oxidative opening; introducing the clay stabilizing composition into a subterranean formation bearing a clay-containing mineral; and interacting the amine-functionalized dextrin compound with the clay-containing mineral to affect stabilization thereof.

Abstract: Friction reducing polysaccharide polymers may be stabilized against thermal degradation in performance using a lactate salt. Accordingly, friction reducing compositions may comprise at least one friction reducing polysaccharide polymer that is non-crosslinked, and a lactate salt. A fluid system may comprise the friction reducing compositions. Methods for mitigating friction may comprise introducing a fluid system comprising a lactate salt and at least one friction reducing polysaccharide polymer that is non-crosslinked into a location subject to friction, and exposing the fluid system to a friction-causing event in the location subject to friction.
