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 …

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 …

This study investigates the potential of a novel CO 2-carbonated water-alternating-gas
(CWAG) injection method for enhanced oil recovery (EOR) and geological carbon storage …

Polymeric nanoparticle (NP) suspensions are colloidal suspensions where NPs (size≤ 100
nm) are suspended in the polymer-enhanced base fluid, mainly water. Compared to water or …

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 …

Carbonated water injection (CWI) is a CO 2-augmented water injection strategy that leads to
increased oil recovery with added advantage of safe storage of CO 2 in oil reservoirs. In …

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 …

In this study, the performance of secondary carbonated water injection (CWI) was
investigated at various operating pressures (ie, P= 0.7–10.3 MPa). Prior to CWI tests, CO2 …

Enriching the injection water with CO 2 has demonstrated encouraging results to improve oil
recovery and securely store CO 2 in underground oil reservoirs. However, the mutual …

Gas injection process for more oil recovery and in particular CO 2 injection is well-
established method to increment oil recovery from underground oil reservoirs. CO 2 …
