Brittleness is a key mechanical characteristic of rock and critical to various engineering
practices particularly to design efficient fracturing stimulation of unconventional shale gas …

Quartz is an important component of shale and has a significant influence on shale physical
properties. However, the specific effects that different quartz types exert on shale porosity …

Hydraulic fracturing is an extensively used technique for development of oil and gas
resources. In the shale reservoir, rock brittleness plays an important role during hydraulic …

Characterizing the origin of natural fractures in organic-rich fine-grained deposits is key to
constraining permeability evolution in these potential source rocks and tight reservoirs, as …

For hydrocarbon exploitation in tight glutenite, glutenite brittleness plays an important role in
fracturing efficiency, but the detailed effect is not entirely clear. In this study, considering rock …

Fractures in organic-rich shale affect the evolution of permeability and control shale gas
preservation. We characterize fracture attributes in the Qiyue-Huaying Fold-Thrust belt in the …

As typical low-permeability unconventional fossil resources, tight sandstone oil cannot be
exploited economically without effective hydraulic fracturing. Fracability is a term commonly …

The safety and efficiency of commercial shale gas development strategies are tightly related
to accurate evaluation of rock deformation and brittle failure processes. In contrast to …

Abstract The Kevin Dome CO 2 storage project, located in northern Montana, attempted to
characterize the Duperow Formation as a potential long-term storage zone for injected CO 2 …

Adsorbed gas can share a significant portion of total gas content in shale reservoirs. At the
same time, the adsorption characteristics of clay‐organic complexes which commonly exist …
