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 …

During the past decades, significant progress has been made in the development of induced
seismicity monitoring for related human activities. Hydraulic fracturing and induced …

Mechanical stratigraphy encompasses the mechanical properties, thicknesses, and interface
properties of rock units. Although mechanical stratigraphy often relates directly to …

Probing source mechanisms of natural and induced earthquakes is a powerful tool to unveil
associated rupture kinematics. The source processes of failure and slip instability driven by …

Abstract 3D fracture network modeling remains a challenging work with the wide application
of microseismic monitoring in multi-stage hydraulic fracturing. Due to the existence of invalid …

Microseismic monitoring is crucial to improving stimulation efficiency of hydraulic fracturing
treatment, as well as to mitigating potential induced seismic hazard. We applied an …

Shales are heterogeneous media with porosity at many scales and in many microtextural
positions, including within organic matter and clay aggregates. Because these materials …

The increasing exploration and production in unconventional resource plays in the past
decade has been accompanied by a greater need for understanding the effectiveness of …

This study characterizes the elastic and fluid flow properties systematically across a ductile–
brittle fault zone in crystalline rock at the Grimsel Test Site underground research laboratory …

Failure of brittle rocks under axisymmetric extensional loading, when the minimum principal
stress is tensile, results in the formation of one or more opening-mode cracks that are …
