Preexisting discontinuities, such as joints and beddings, are widely distributed in
unconventional reservoirs. During fluid injection, hydraulic fractures strongly interact with …

Extraction of geothermal energy, oil and gas, and coalbed methane (CBM) are all
constrained by the rock's permeability. To stimulate the production, hydraulic fracturing has …

A novel model is proposed to simulate radon migration by combining the fractal theory and
the discrete fracture network (DFN) model. In the model, a power-law distribution based on …

In underground engineering, tunnels are important passages for underground wastewater,
personnel and vehicles. As the surrounding rock usually experiences the splitting failure, the …

The engineering water inrush events were affected by the hydraulic characteristics of the
fractures. In order to quantitatively study the seepage characteristics of the fractures, the …

To explore the mechanical properties of fractured rock masses under complex stress paths,
shear creep tests on marble under different fatigue conditions were conducted; the effects of …

The objective of this study is to simulate the two-phase flow in pipes with various two-fluid
models and determinate the shear stress. A hyperbolic shear deformation theory is used for …

The sandstone-mudstone interbedded reservoirs in Bohai Bay Basin, eastern China are
typically characterized by high in-situ stress difference, low permeability, and significant …
