Micellar flooding process for recovering oil from petroleum reservoirs
Patent
·
OSTI ID:7303445
Oil recovery efficiency of tertiary oil recovery processes using a micellar solution as the displacement fluid is improved by injecting a dilute aqueous solution of an alkali metal silicate into the reservoir subsequent to the micellar solution injection and prior to the drive fluid injection. The alkali metal silicate has a M/sub 2/O/SiO/sub 2/ ratio of between 1 and 4. 14 claims.
