Understanding the transport of hydraulic fracturing (HF) fluid that is injected into the deep
subsurface for shale gas extraction is important to ensure that shallow drinking water …

After the initial development of the first TOUGH-based geomechanics model 15 years ago
based on linking TOUGH2 multiphase flow simulator to the FLAC3D geomechanics …

Gas production from hydrates induced by depressurization is a complex thermal-
hydrodynamic-mechanical–chemical (THMC) coupled process. In this paper, we present a …

We perform numerical studies on vertical fracture propagation induced by tensile hydraulic
fracturing for shale gas reservoirs. From the numerical simulation, we find that tensile …

Unconventional geomaterials often exhibit multi-modal pore size distribution. We have
developed a comprehensive framework for porous media exhibiting multiple porosity scales …

Pulse hydraulic fracturing (PHF) is a new stimulation technique to enhance effectively
permeability of coal seams, increasing the efficiency of gas extraction. However, the …

Geomaterials containing fissures such as some sedimentary rocks often exhibit a bimodal
pore size distribution, and they are also inherently anisotropic due to the distinct bedding …

This paper presents a coupled thermal-hydraulic-mechanical (THM) model for simulating
failure processes in geological media. The coupling between stress/strain and heat transfer …

Hydrocarbon production from unconventional resources and the use of reservoir stimulation
techniques, such as hydraulic fracturing, has grown explosively over the last decade …

In this paper, a novel hybrid FEM and Peridynamic modeling approach proposed in Ni et
al.(2020) is used to predict the dynamic solution of hydro-mechanical coupled problems. A …
