Introduction: geology of fractured reservoirs
Journal of the Geological Society, 2020 The characterization of fractured reservoirs and fractured geothermal resources requires a thorough understanding of the geological processes involved during fracturing and the rheological properties of the host rock.

Influence of Shear Displacement on Fluid Flow and Solute Transport in a 3D Rough Fracture
Lithosphere, 2021 Fractured rocks in the subsurface are ubiquitous, and the dynamics of mass transfer in fractured rocks plays an important role in understanding the problem in engineering geology and environmental geology.

On the hydraulic fracturing in naturally-layered porous media using the phase field method [PDF]
Engineering Geology, 2020, 266: 105306, 2023 In the hydraulic fracturing of natural rocks, understanding and predicting crack penetrations into the neighboring layers is crucial and relevant in terms of cost-efficiency in engineering and environmental protection. This study constitutes a phase field framework to examine hydraulic fracture propagation in naturally-layered porous media.

Quantification of bound water content, interstitial porosity and fracture porosity in the sediments entering the North Sumatra subduction zone from Cation Exchange Capacity and IODP Expedition 362 resistivity data [PDF]
Marine and Petroleum Geology, Elsevier, 2020, 111, pp.156-165, 2020 In this study, we investigate porosity evolution through the sedimentary input section of the North Sumatra Subduction zone by quantifying interstitial porosity, bound water content and fracture porosity based on IODP Expedition 362 data and post-cruise chemical analyses.

Natural fracture propping and earthquake-induced oil migration in fractured basement reservoirs
Geology, 2019 The geological processes that create fluid storage capacity and connectivity in global fractured basement reservoirs are poorly understood compared to conventional hydrocarbon plays.

A phase-field modeling approach of fracture propagation in poroelastic media [PDF]
Engineering Geology, 2018, 240: 189-203, 2019 This paper proposes a phase field model for fracture in poroelastic media. The porous medium is modeled based on the classical Biot poroelasticity theory and the fracture behavior is controlled by the phase field model. Moreover, the fracture propagation is driven by the elastic energy where the phase field is used as an interpolation function to ...

Fracture healing and strength recovery in magmatic liquids
Geology, 2019 Cycles of fracture and healing in magma are important controls on outgassing time scales and repetitive seismicity at silicic volcanoes. Here, we experimentally drove silicate melts (at 109–1011 Pa·s) to tensile failure, measuring the strength during ...
