Capturing carbon dioxide (CO 2) at its combustion point and thereby storing it in geological
sites or its usage for enhancing oil recovery (EOR) through miscible gas flooding technology …

Global shale oil is abundant in geological reserves, but there are widespread problems of
difficult exploitation and unsatisfactory oil recovery. CO 2 injection in shale reservoirs can …

Heavy oil resources have become increasingly important in recent years due to a reduction
in light oil production and an increase in energy consumption. A large number of heavy oil …

Foam-based fracturing fluid application in unconventional reservoirs has recently attracted
prodigious attention, due to their high apparent viscosity and ultra-low water contents, which …

In this study, experimental and mathematical studies were carried out to investigate heavy
oil production performance using the carbon dioxide (CO 2) huff-n-puff process, as well as …

Recent evidence suggests that CO 2 huff-n-puff can significantly enhance the oil recovery in
tight/shale oil reservoirs after primary depletion. However, the key driving forces of CO 2 huff …

CO 2-assisted EOR technologies appear to be low-cost and eco-friendly means to boost
crude oil production of dense reservoirs. The potential of CO 2 huff-n-puff process and CO 2 …

Horizontal well re-fracturing of tight reservoirs triggers complex fractures, which induces
severe gas channeling and low sweeping efficiency in CO 2 flooding due to the significance …

Carbon dioxide (CO 2) emissions present one of the world's most pressing issues as a
primary drive for climate change. This requires a viable solution through capture and storage …

The complicated flow behaviors of multiphase fluids in shale reservoirs are significantly
influenced by fluid-fluid and fluid-rock interactions due to the non-negligible intermolecular …
