Natural fractures have long been suspected as a factor in production from shale reservoirs
because gas and oil production commonly exceeds the rates expected from low-porosity …

Spontaneous imbibition behavior gained popularity several decades ago which led to
widely exploited application in fractured reservoirs. Recently the imbibition behavior of …

Although research on CO 2 injection in shale gas reservoirs has been focused for enhanced
gas recovery (EGR) and CO 2 storage, previous studies have not examined both multi …

The mechanical and creep properties of shale strongly influence artificial hydraulic
fracturing, wellbore stability, and the evaluation of reservoir performance in shale gas …

The economic production of gas and oil from shales requires repeated hydraulic fracturing
operations to stimulate these tight reservoir rocks. Besides simple depletion, the often …

Creep of shale controls the stability of fault gouge in sedimentary rocks, aseismic
deformation in the upper crust, and several engineering operations, such as proppant …

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

Safety assessment of geological nuclear waste repositories is essential for the permanent
disposal of spent nuclear fuels and high-level radioactive waste. The long-term integrity of …

In this study, three shale samples from the Wolfcamp Formation in Permian basin were
selected and studied for creep behavior using two different methods at macro-and micro …

Shale is known to exhibit significant creep across spatiotemporal scales. In this work, we
performed indentation and triaxial creep tests on organic-rich Woodford shale and showed …
