... and processes associated with the creation and evolution of an EDZ in the Opalinus Clay. In particular, the significance of rock mass anisotropy is highlighted both as a likely origin for far-reaching pore fluid pressure changes and as a controlling factor in EDZ development during the excavation process. 1...

... or multiphysics. Some advantages are for instance that fluid pressure discontinuities and localized flow lines may be represented on the same FE mesh used for the mechanical problem, as well as the influence of fluid pressure on mechanical stresses or, conversely, of crack openings on the flow redistribution...

... on microseismic data clearly show that fluid-pressure-driven frac- tures interact with preexisting discontinuities, thus highlighting the strong influence of rock mass structures on hydraulic fracture development. However, these mechanisms are not well accounted for by analytical models and conventional continuum...

... for 20 hours. Spatio-temporal distribution of fluid pressure, injection/production induced seismic events, their magnitudes and source characters are investigated. The simulation shows that production induced seismic events mostly occur along the line at steep fluid pressure gradient with mostly...

... that the values of vertical displacements are lower to cases with compressible fluids than to those with incompressible fluids. Instantaneously after load application, fluid pressure increases to a maximum value and it dissipates as load is gradually transferred to solid matrix. For compressible fluids, however...
