The oxidation of fossil fuels produces billions of tons of anthropogenic carbon dioxide (CO 2)
emissions from stationary and nonstationary sources per annum, contributing to global …

Carbon emissions have caused serious climate changes such as global warming, glacier
melting, and sea level rise. Carbon neutrality has become a global target and the …

Primary oil recovery from fractured unconventional formations, such as shale or tight sands,
is typically less than 10%. The development of an economically viable enhanced oil …

The wettability of reservoir rocks is considered to be closely related to fluid distribution and
CO 2 geo-storage (CGS) security after injecting CO 2 into reservoir. To investigate the …

A combination of high-resolution imaging, low-pressure gas adsorption, and small-angle X-
ray and neutron scattering quantifies changes in the pore characteristics of pulverized shale …

The permeability of shale reservoir rock and caprock is the key parameters influencing the
shale gas production and the storage security of CO 2. During the CO 2 enhanced shale gas …

Due to the complexity of sedimentary rocks, especially the fine-grained and highly-
heterogeneous nature of some argillaceous caprocks in the subsurface, it is challenging to …

Shale is a source rock for hydrocarbon recovery that can be stimulated by CO 2-based
fluids, as well as a caprock for CO 2 geological sequestration due to its extremely low …

CO2–shale interaction performs a crucial role in determining the capacity and leakage risk
of CO2 storage in shale reservoirs. In this paper, the alterations of physical and chemical …

Shales have been a major focus of the energy industry over the past few decades. Recently,
there is a paradigm shift in the energy industry to low-carbon solutions, such as carbon …
