“…Controlling CO 2 mobility makes it possible to increase oil recovery more cheaply and efficiently, with associated positive effects that mitigate CO 2 entering the atmosphere. 4 There are several ways to adjust the CO 2 phase when injecting it into the reservoir to increase oil recovery: 7 CO 2 –water alternating gas (WAG) injection, Polymer additives for direct thickening of CO 2 , In situ polymer gels for CO 2 conformance control, Preformed polymer gels for CO 2 conformance control, Surfactant-assisted CO 2 mobility control, and NP-enhanced CO 2 flooding. …”

“…NP surface treatments can be used to target specific molecules, thereby promoting the formation of a CO 2 /water foam without the formation of oil/water emulsions. 7 In this process, NPs and nanofluids influence the interfacial tension (IFT), rheological properties, and wettability of surfaces. Polymer solutions and surfactants can be modified by adding NPs to alter the rock wettability, reduce IFT, and improve rheological properties.…”

Carbon dioxide (CO 2 ) in enhanced oil recovery (EOR) has received significant attention due to its potential to increase ultimate recovery from mature conventional oil reserves. CO 2 -enhanced oil recovery (CO 2 -EOR) helps to reduce global greenhouse gas emissions by sequestering CO 2 in subterranean geological formations. CO 2 -EOR has been exploited commercially over recent decades to improve recovery from light and medium gravity oil reservoirs in their later stages of development. CO 2 tends to be used in either continuous flooding or alternated flooding with water injection. Problems can arise in CO 2 -flooded heterogeneous reservoirs, due to differential mobility of the fluid phases, causing viscous fingering and early CO 2 penetration to develop. This study reviews the advantages and disadvantages of the techniques used for injecting CO 2 into subsurface reservoirs and the methods adopted in attempts to control CO 2 mobility. Recently developed methods are leading to improvements in CO 2 -EOR results. In particular, the involvement of nanoparticles combined with surfactants can act to stabilize CO 2 foam, making it more effective in the reservoir from an EOR perspective. The potential to improve CO 2 flooding techniques and the challenges and uncertainties associated with achieving that objective are addressed.

Microfluidic Study of the Effect of Nanosuspensions on Enhanced Oil Recovery

The essential advantages of microfluidic studies are the excellent visualization of the processes of oil displacement from the porous medium model, simple cleaning, and the possibility of the repeated use of the microfluidic chip. The present article deals with the process of oil displacement by suspension flooding using a microfluidic chip, simulating a porous medium, and the suspensions of silicon dioxide nanoparticles (22 nm). The mass concentration of nanoparticles in suspensions ranged from 0.1 to 2 wt%. Five mass concentrations (0.125 wt%, 0.25 wt%, 0.5 wt%, 1 wt% and 2 wt%) were considered. The article presents the experimental photographs of the oil displacement process by water and SiO2 suspension. It is shown that, with the increasing concentration of nanoparticles, the oil recovery factor increases. A significant effect is observed at 0.5 wt% concentration of nanoparticles. It is shown that the increase in oil recovery during flooding by SiO2 suspension with the maximum concentration was 16%.

“…It is estimated that more than 50% of original-oil-in-place remains unrecovered after the primary and secondary phases of oil recovery. 1 Enhanced oil recovery (EOR) is applied as a tertiary recovery phase. Gas injection or miscible flooding is nowadays a widely used method in EOR.…”
