Hunter, W D

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 polyacrylamide or partially hydrolyzed polyacrylamide or the sodium, potassium or ammonium salt thereof and a minor amount of polyacrylamide or partially hydrolyzed polyacrylamide or the sodium, potassium or ammonium salt thereof alkoxylated with an alkylene oxide. Optionally, the drive fluid can be saturated with carbon dioxide and/or natural gas at the injection pressure. An aqueous fracturing fluid containing a small amount of alkoxylated polyacrylamide or partially hydrolyzed polyacrylamide is also described.
