  • POLYAMINE SALTS AS CLAY STABILIZING AGENTS
    Publication number: 20080108523
    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.
    Type: Application

    Inventors: DAVID POELKER, JOANN MCMAHON, JOHN SCHIELD
  • High molecular weight polyamine salts as clay stabilizing agents
    Publication number: 20060254772
    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.
