Abstract: Reaction products produced by reacting a maleated tall oil fatty acid and/or a maleated soy oil fatty acid with an ethylene amine material are used as clay inhibitors in drilling fluids and in hydraulic fracturing fluids for drilling wells and for fracturing subterranean formations, and are also used as clay inhibitors in other treatment fluids for treating wells or subterranean formations.

Abstract: A method of producing a cationic asphalt slurry composition which can be used as an asphalt paving sealer or as a paving or repair composition. In the method and composition, latex and other polymers are used to build viscosity and a pH buffering filler is added to prevent flocculation. Consequently, the cationic composition can be stored without irreversibly settling or separating, and without breaking for several days prior to use. In addition, non-expansive clay and a polar polymer hardening agent are used so that, when applied, the composition will set and develop strength very quickly.
