| Outline of Final Research Achievements |
We conducted a basic research to use cellulose nanofiber (CNF) suspension as an injection fluid to enhanced oil and gas recovery (EOGR). The CNF suspension is biodegradable and safe for human. Therefore, this research is aimed to contribute both to providing a stable supply of oil and gas and to solving environmental problems in the development of them. As a result of our research, it was found that the CNF suspension, compared to other thickeners, has poor injectivity to oil and gas reservoir rocks. But, it was also found that it can be applied to injection profile modification for EOGR and improve recovery of oil and gas, if it can be injected into the reservoir rocks. In this research, we tried to inject the CNF suspension into a Berea sand stone core as an inclusion of W/O emulsion with a diameter of 1 μm or less and we were succeeded in injecting it into a Berea sandstone easily.
