ABSTRACT:
A stable latex composition possessing a viscosity of less than about 50 cp. comprised of an ethylacrylate/methylacrylic acid/acrylic acid polymer and co-surfactant system comprising a nonylphenol polyethylene oxide ether sulfate and a propoxylated, ethoxylated propylene glycol nonionic surfactant block polymr useful for increasing the viscosity of water that is injected into subterranean petroleum bearing formations for the enhanced recovery of the petroleum.
