The development of hydraulic fracturing and horizontal drilling techniques has promoted the
exploitation of shale gas resources. However, using water has several potential drawbacks …

CO 2 sequestration has proven to be an attractive way to combat global warming. However,
due to the corrosive nature of CO 2, chemical reactions between CO 2 and the host rock can …

Hydraulic fracturing has transformed the international energy landscape by becoming the go-
to method for the exploitation of natural gas from unconventional shale reservoirs. However …

Unconventional oil and gas resources, such as shale gas and tight oil, are increasingly
important in the energy structure; however, these reservoirs have poor physical properties …

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 …

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 …

Fluid–shale interaction mechanisms and their implications on shale mechanical property
evolutions are essential for both shale gas exploitation and CO2 sequestration. To …

Supercritical carbon dioxide (SC–CO 2) serves as a promising anhydrous fracturing fluid
that has the potential to simultaneously enhance shale gas recovery and accomplish CO 2 …

Dynamic mass transfer due to spontaneous imbibition is of significant importance in various
scientific and engineering applications, including environmental remediation, chemical …

Shale is featured by nanometer pores and ultralow permeability. Enhancing shale oil
recovery after primary production is challenging as a result of the low injectivity of water …
