Polyamine salts as clay stabilizing agents |
| abstract |
A clayish subterranean formation, such as may be encountered in rock surrounding a well bore during hydrocarbon recovery operations may be stabilized with a polyamine salt of an imide of polymaleic anhydride. The salt may be unneutralized or partially neutralized. The invention is particularly relevant to hydraulic fracturing fluids used in enhanced oil recovery. The compositions of this invention are more environmentally friendly than some current technology. |
