| titleOfInvention | Cationic coatings for improved nanoparticle transport in a carbonate reservoir |
| abstract | Coated nanoparticles include nanoparticles with a cationic coating, such that the nanoparticles have a net-positive charge. The cationic coatings may be selected from an amino acid, a polysaccharide, a polyamine, an acrylate polymer, a dendrimer, a copolymer, a histone, a protein, an ester, or combinations thereof. The coated nanoparticles may be incorporated into methods for improving an amount of oil recovered during enhanced oil recovery. The methods may include introducing an aqueous drilling fluid comprising coated nanoparticles to a carbonate reservoir and injecting drilling fluid comprising the coated nanoparticles into the carbonate reservoir to displace oil in the carbonate reservoir and thereby enhance the oil recovery. |
