Abstract

Water flooding is an efficient approach to maintain reservoir pressure and has been used widely to enhance oil recovery. However, preferential water pathways generated after long-term water flooding process and the strongly heterogeneous reservoirs can significantly decrease the sweep efficiency. Therefore, the utilization ratio of injected water is seriously affected. Most water-flooded reservoirs are in their late development stage, and their water cuts are more than 90%. How to develop new flooding technology to further improve the oil recovery is a pressing problem. Ferrofluids are colloidal suspensions of magnetic particles of diameter approximately 10 nm stabilized in various carrier l..
