Retrieval of Solvent Injected During Heavy-Oil Recovery in Heterogeneous Porous Media: Pore Scale Analysis through Micro Model Experiments
DownloadFall 2016
Solvent retrieval is essential for the economics of the solvent-related heavy-oil recovery technologies. In fractured and oil-wet reservoirs, water-flooding followed by solvent is not suitable to achieve this goal. Two methods can be proposed as solution to solvent retrieval in complex...

Solvent retrieval and wettability alteration during heavy-oil and bitumen recovery by SOS-FR (steam-over-solvent injection in fractured reservoirs) method
DownloadFall 2014
Mohammed, Mohammedalmojtaba Y.S.
Water injection is inefficient to recover heavy oil from naturally fractured carbonate reservoirs mainly due to its oil-wet nature of the matrix. Solvent injection could be an option in this type of reservoir through dilution of oil and gravity drainage. This, however, will only be feasible if...
