Unconventional resources like shale gas has been the focus of intense research and
development for two decades. Apart from intrinsic geologic factors that control the gas shale …

The organic carbon-and uranium-rich, marine Alum Shale Formation in northwestern
Europe (Middle Cambrian (Miaolingian) to Early Ordovician) was deposited in the Baltic …

The geomechanical integrity of shale overburden is a highly significant geological risk factor
for a range of engineering and energy-related applications including CO _2 2 storage and …

Brittle-ductile transition conditions and mechanisms are key scientific issues embedded in
the reservoir deformation-related difficulties faced during shale gas exploration and …

Hydraulic fracturing (HF) at Preston New Road (PNR), Lancashire, United Kingdom, in
August 2019, induced a number of felt earthquakes. The largest event (ML 2.9) occurred on …

The mechanical behavior of brittle ductile transition in rocks is one of the essential
components of deep rock mechanics, as well as a key factor that impacts the safe and …

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 …

This study investigates the nano to core‐scale geomechanical properties of a maturity series
of organic‐rich, calcareous shales buried to 100° C–180° C, with a focus on:(a) the …

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 …

Although many studies based on naturally deformed samples have been carried out to
investigate the pore-crack characteristics of shales, studies based on high temperature (T) …
