Capture and subsurface storage of CO 2 is widely viewed as being a necessary component
of any strategy to minimise and control the continued increase in average global …

In carbon storage activities, and in shale oil and gas extraction (SOGE) with carbon dioxide
(CO2) as stimulation fluid, CO2 comes into contact with shale rock and its pore fluid. As a …

Shales are considered to be both source and cap rocks, and play an important role in
various geotechnical applications including oil and gas exploration and production. A deep …

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 are heterogeneous sedimentary rocks which typically comprise a variable
mineralogy (including compacted clay particles sub-micrometer in size), silt grains, and …

Shale reservoirs have gained the attention of many in recent years due to their potential as a
major gas resource. Production from this kind of formation, however, requires an accurate …

To understand the geomechanical implications of long-term creep (time-dependent
deformation) response of gas shale, short-duration creep was recorded from laboratory …

Shale composition might influence the petrophysical properties of shale reservoirs. The
relationships among composition, porosity and permeability of Longmaxi Shale in Weiyuan …

We tested samples cored from the Vaca Muerta shale reservoir using nanoindentation (2
min) and triaxial (12 hr) creep experiments in which confining pressure and differential …

The evolution of shale's mechanical properties with confining pressure, temperature, and
mineral composition directly influences fracture closure besides the effect of in situ stress …
