.... The experimental results revealed that a significant improvement in the oil recovery can be achieved through alteration of the injection water salinity. Reducing the salinity of UER water from 197,362 ppm to 5000 ppm resulted in an improvement of oil recovery from 63% to 84.5% of OOIP and the latter salinity...

The average waterflooding recovery was found to be 75.1 % of OOIP (out of 19 experiments) whereas surfactant injection (modified waterflooding) yielded an average of 69.9 % of OOIP (out of 8 experiments). This indicates that the surfactant injection is not preferable and not recommended...
