Carbonated water injection (CWI) is a promising enhanced oil recovery (EOR) technique in
which the dissolved CO 2 can transfer to the oil phase to improve the oil mobility and to …

Due to the feature of tight formation, the primary oil recovery is usually very low and leaves
substantial oil still in place. This fact results in a strong motivation of applying an enhancing …

Carbonated water injection (CWI) is a promising enhanced oil recovery (EOR) technology
that has received much attention in co-optimizing CO 2 storage and oil recovery. This study …

Low volumetric sweep efficiency, early breakthrough of injected fluid, and high risk of gas
leakage from the reservoir are the major technical challenges associated with direct gas and …

During this study, a comprehensive investigation of low salinity water alternating CO 2
injection was performed for enhanced oil recovery in oil-wet carbonate reservoirs. A synergy …

The benefits and advantages of waterflood are well-known with many decades of
application in a wide range of reservoirs with different crude oil and rock types. However, the …

Abstract Specification of CO2 and brine phase behaviour plays a vital role in CO2
sequestration and CO2 reduction from atmosphere to deep saline aquifers. Because CO2 …

Wettability of oil-brine‑carbonate system is an important petro-physical parameter, which
governs subsurface multiphase flow and residual oil saturation. CO 2-assisted EOR …

Although CO 2 huff-n-puff process has been widely employed as an efficient oil recovery
and carbon storage technique in unconventional reservoirs, it suffers from the …

Long-term CO2 injection will induce natural fractures to open and form an induced fracture
network, which is dynamic during injection and shut-in because there is no proppant in the …
