| titleOfInvention |
Stable mixtures of polymers and surfactants for surfactant flooding |
| abstract |
An improved fluid for surfactant flooding a subterranean oil-bearing reservoir is prepared by contacting polymer with fresh water in the substantial absence of a salt; thereafter combining the thus-formed polymer solution and a salt solution; and finally adding a surfactant. |
