Primary oil recovery remains less than 10% in tight oil reservoirs, even after expensive
multistage horizontal well hydraulic fracturing stimulation. Substantial experiments and pilot …

Due to the complexity of sedimentary rocks, especially the fine-grained and highly-
heterogeneous nature of some argillaceous caprocks in the subsurface, it is challenging to …

Formation damage caused by fine migration and straining is a well-documented
phenomenon in sandstone reservoirs. Fine migration and the associated permeability …

CO 2 huff-n-puff can store CO 2 and improve the recovery of tight oil reservoir. The
asphaltene precipitation produced by the interaction of CO 2 and oil causes damage to tight …

Carbon dioxide miscible flooding has been proven to be one of the most effective enhanced
oil recovery (EOR) technologies, particularly for light and medium oil reservoirs. However …

Carbonated water injection (CWI) might be an efficient alternate to CO 2 injection technique.
In CWI, CO 2 exists as a dissolved phase and not as a free phase; thus, it eliminates some …

CO 2 injection into hydrocarbon reservoirs can simultaneously pave the path for two
important processes, namely oil production increase, and CO 2 storage. This combined …

The recoverable hydrocarbon reserves of conventional oil and gas resources are very
limited in China. As important alternative resources, unconventional oil and gas have …

CO 2 trapping in porous media is one attractive sequestration option in which the CO 2
trapped for long periods and also enhanced oil recovery (EOR) simultaneously. The aim of …

Pore and throat blockage and wettability alteration caused by asphaltene deposition are
serious problems during the injection of CO2 into subsurface reservoirs for enhanced oil …
