ABSTRACT:
Hydrocarbons are recovered from a subterranean hydrocarbon-bearing formation penetrated by an injection well and a production well by displacing hydrocarbons toward the production well using a drive fluid such as water thickened with a copolymer of (a) vinyl sulfonic acid alkoxylated with 2,3-epoxy-1-propanol and (b) acrylamide. Optionally, the drive fluid can be saturated with carbon dioxide and/or natural gas at the injection pressure.
