Modern technology must meet the urgent need for net-zero global carbon emissions to
mitigate the deleterious effects of fossil fuel consumption. CO 2 utilization in fields such as oil …

As the global oil market continues to tighten, there is an increasing focus on enhancing oil
recovery. However, enhanced oil recovery technologies require the addition of chemical …

Enhanced oil recovery (EOR) has been widely used to recover residual oil after the primary
or secondary oil recovery processes. Compared to conventional methods, chemical EOR …

CO 2 flooding is often used in low permeability reservoirs, but there is general fracture in the
reservoir, resulting in the problem of gas channeling. To achieve anti-gas channeling in …

Different salt ions with different concentrations can affect the fracturing effect by influencing
the stability of the carbon dioxide-in-water (C/W) foam during C/W foam fracturing to …

Producing CO 2-foams in saline environments can be a great challenge in many industrial
applications, since fast gas diffusion and reduction of electrical double layer promote fast …

The use of foam technology in Pre-Salt reservoirs is a potential solution to control gas
mobility in highly heterogeneous reservoirs. However, achieving stable CO 2-foams under …

With the urgent need for energy and reduction of carbon emissions around the world, the
use of carbon dioxide foam flooding in enhanced oil recovery and CO 2 storage in …

Investigation of methods to effectively block the high-permeability channel and displace the
residual oil in the small pores in the old oilfields is an urgent research hotspot. The heat …

Tight oil reservoirs have poor physical properties, insufficient formation energy, and low
natural productivity. CO2 flooding is an important technical mean that enhances the oil …
