Abstract: A method of preparing and using a subterranean formation stabilization agent. The stabilization agent includes a guanidyl copolymer and may be admixed with a fracturing fluid and optionally brine. The stabilization agent is effective in preventing and/or reducing, for example, clay swelling and fines migration from a subterranean formation contacted with the stabilization agent.

Abstract: Aqueous suspensions of paints in waste waters can be treated to detackify the paint and facilitate its removal by contacting the paint suspension at a pH of from about 5 to about 14 with a polyarylamine that is produced by reacting an aldehyde with an arylamine in the presence of an acid in an aqueous suspension. The same polyarylamine can also be used for reducing the color content of highly colored liquids. Compositions containing the polyarylamine are also described.

Abstract: The current invention describes organoclay compositions and methods of using them for removing impurities from contaminated liquids. The compositions are formed by contacting an attapulgite, sepiolite, or zeolite clay mineral with an alkylamine base. The method of use involves contacting the organoclay composition with a contaminated liquid, such as oil in water, allowing the organoclay to absorb the contaminants. The organoclay can be in the form of a granular solid for inline filter applications, or it can be a finely divided powder for other applications.
