Abstract: A clayish subterranean formation, such as may be encountered in rock surrounding a well bore during hydrocarbon recovery operations may be stabilized with relatively high molecular weight acid ammonium salts of an imide of polymaleic anhydride. The salts may be unneutralized or partially neutralized. The invention is particularly relevant to hydraulic fracturing fluids used in enhanced oil recovery. The compositions herein are made in the presence of a reactive solvent, such as a polyalkylene glycol, e.g. polyethylene glycol. The compositions of this invention are more environmentally friendly than some current technology.

Abstract: Disclosed is composition useful for reducing the concentration of mercaptans in hydrocarbons comprising: (A) a first diazo component and (B) a second component comprising a nucleophilic acceptor. The composition can be added to hydrocarbons such as fuel oil to reduce mercaptans without increasing turbidity or color. Triethylene diamine and 1,2-epoxyhexadecane are disclosed to be exemplary diazo and nucleophilic acceptor components.
