Enhanced oil recovery methods and systems
Patent
·
OSTI ID:5675164
A method is disclosed of enhanced oil recovery from subterranean oil-containing formations via injection through an injection well penetrating the formation of a viscous aqueous solution, containing one or more water-soluble organic polymers and forcing such solution through the formation towards a production well for ultimate recovery. The viscous aqueous polymer solutions of the invention are prepared at the site of their use by polymerizing one or more water-soluble polymerizable vinyl monomers in aqueous solutions, which may contain high concentrations of one or more salts.
