COMPOSITION OF MICROEMULSION AND METHOD FOR ADVANCED RECOVERY OF HEAVY OIL |
摘要 |
This invention describes a composition of microemulsion comprising a mixture of a combination of surfactants and co-surfactants, an oil phase and an aqueous phase; and a method for advanced recovery of heavy oil comprising stages of: injection of a bank containing the said microemulsion composition, injection of a bank of a polymer solution, and injection of water. This microemulsion composition can be applied in arenitic and carbonatic reservoirs, containing oils with API below 22.3° API, in both onshore and offshore fields. |
