  • Polymers and nanoparticles formulations with shear-thickening and shear-gelling properties for oilfield applications
    Patent number: 8240380
    Abstract: Compositions having shear-gelling and shear-thickening properties are based on an amphiphilic polymer combined with hydrophilic particles and polyethyleneoxide. The hydrophilic particles preferably consist of a hydrous sodium lithium magnesium silicate. The amphiphilic polymer may be a synthetic polymer, a hydrophobically modified biopolymer, or both. The compositions may be employed in enhanced oil recovery operations.
