After soaking in organic salt drilling fluid, the strength of rock sample weakens, drilling fluid fills the fracture surface to a certain extent. After soaking in oil-based drilling fluid, the strength of rock sample weakens, and oil-based drilling fluid fills and closes the fracture surface. ...
It is the most common sedimentary rock and is found in sedimentary basins worldwide. ADVERTISEMENT What is Shale? Shale is a fine-grained sedimentary rock that forms from the compaction of silt and clay-size mineral particles that we commonly call "mud." This composition places shale in a ...
Solid organic matter (OM) plays an essential role in the generation, migration, storage, and production of hydrocarbons from economically important shale rock formations. Electron microscopy images have documented spatial heterogeneity in the porosity of OM at nanoscale, and bulk spectroscopy measurements...
Hydraulic fracturing, or fracking, is a technique designed to recover gas and oil from shale rock (Image Credit: Public Domain). This poem is inspired byrecent research, which suggests that fracking may be responsible for the increase in atmospheric methane that has been observed over the past ...

Establishing the links between the composition, microstructure and mechanics of shale continues to be a formidable challenge for the geomechanics community. In this study, a robust methodology is implemented to access the in situ chemomechanics of this sedimentary rock at micrometer length scales. Mass...
