Oil recovery method and alkyl alkoxy propio sulfonate surfactants |
| abstract |
Abstract New alkyl alkoxy propio sulfonate compounds are disclosed. These materials are useful as additive to aqueous solutions employed to obtain enhanced or further recoveries from petroleum bearing formations. When added to brine solutions such as are available in the field, the materials exhibit improved stability against hydrolysis at elevated temperatures and for prolonged periods. |
