Impact of Induced Thermal Stresses during Circulation Tests in an Engineered Fractured Geothermal Reservoir: Example of the Soultz-sous-Forêts European Hot Fractured Rock Geothermal Project, Rhine Graben, France — The wider concept of hot fractured rock geothermal energy is put forward to overcome the natural limitations of classic geothermal fields. A suite of numerical modules based on a disc...

Considered the characteristics of porous medium in coal seam and goaf, order to reflect accurately influence various media against gas flow, mathematical model discrete multi-scale network macroscopic CFCM (Coal-Fracture-Cavity-Model), was presented. The is classified into matrix, fracture hole systems based on size, matrix system includes micro fractures micro-porous. can be regarded as diffus...

Abstract In this study, the correlation between geometric properties of fracture network and stress variability in a fractured rock was studied. Initially, discrete networks were generated using stochastic approach, then, considering tensorial nature stress, field under various tectonic conditions determined finite-difference method. Ultimately, data analyzed tensor-based mathematical relations...

Abstract The role of natural fractures in future reservoir performance is prominent. fractured porous media composed an interconnected network and blocks the medium where occur various scales have a strong influence either when most flow concentrated them or they act as barriers. A general numerical model for discrete fracture networks (DFN) usually employed to handle observed wide variety prop...

We discuss techniques to represent groundwater flow in carbonate aquifers using the three existing modeling approaches: equivalent porous medium, conduit network, and discrete fracture network. Fractures faulted stratigraphic successions are characterized by dominant sets of sub-vertical joints. Grid rotation is recommended medium match higher hydraulic conductivity with orientation Modeling fa...
