Process for secondary recovery |
| 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 acrylamide and vinyl sulfonic acid or salts thereof and saturated with carbon dioxide and/or natural gas at the injection pressure. If desired, the drive fluid may contain a small amount of a sulfated or sulfonated, ethoxylated acrylic acid polymer. |
