OIL RECOVERY PROCESS USING POLYALKENE OXIDE POLYMER SOLUTIONS WITH ADDED CATIONS |
| 摘要 |
Oil is displaced from oil-bearing formations by injecting into the formations aqueous compositions which include polyalkene oxide polymers and controlled quantities of alkaline earth metal ions. Similar compositions can also be used as viscosity increasing ingredients in other applications.
