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. The presence or absence of mechanical layering within the rock and the mode of failure substantially control the organization and ...

Geology of the Rokko Tunnel with reference to fracture pattern
Journal of the Japan Society of Engineering Geology, 1968 The Rokko Tunnel built up in April 1967 is 2843m in length and combines Kobe with the Sanda basin in lesser distance. During its construction, geological survey with datailed mapping in scale of 1/100 was attempted and the results are summarized as follows:The wall of the tunnel consists of the quartz diorite, granite and rarely lithoidite.

Geology and fracture system at Stripa. Technical information report No. 21 [PDF]
, 1979 The Stripa test site has been excavated in granitic rock between 338 m and 360 m below the ground surface, and is located under the north limb of an ENE-plunging synclinal structure. The granitic rocks, in the areas mapped, are of Archean age and are dominated by a reddish, medium-grained, massive monzogranite that shows varying degrees of deformation.

Application of Freezing Method in the Geology Disaster Treatment of Fault Fracture Zone
DEStech Transactions on Engineering and Technology Research, 2017 Fault rupture zone inrush of water and mud is the most serious geological disaster of the tunnel and underground engineering. The disaster has a direct threat to the progress of engineering and the safety of builders. The Yonglian tunnel appears to multiple inrush of water and mud disaster in the process of construction Geological environment and ...

Review of discrete fracture network characterization for geothermal energy extraction
Frontiers in Earth Science, 2023 Geothermal reservoirs are highly anisotropic and heterogeneous, and thus require a variety of structural geology, geomechanical, remote sensing, geophysical and hydraulic techniques to inform Discrete Fracture Network flow models.

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.
