Rock Damage and Fluid Transport, Part II,t was held at the GeoForschungsZentrum Potsdam, Germany in September 2004. Part I of this volume (Pure and Applied Geophysics, Volume 163, No. 5) mainly contains papers related to problems of rock damage, fracture mechanics, and stresses in rock. Part II contains contributions on transport propertie

Short-Timescale Chemo-Mechanical Effects and their Influence on the Transport Properties of Fracturn and net removal of mineral mass, fractures may alternately gape or seal, depending on the prevailing mechanical and chemical conditions. The influence on transport properties is observed to be large, rapid, and irreversible: Permeabilities may change by two orders of magnitude in a month, and the

Permeability Evolution During Non-linear Viscous Creep of Calcite Rocks,% quartz. Both isostatic and conventional triaxial loading conditions were used. The tests were performed at confining pressure of 300 MPa, pore pressures between 50 to 290 MPa, temperatures from 673 to 873 K and strain rates of 3 × 10. s.. Argon gas was used as the pore fluid. The initial porositie

Determination of Porosity and Permeability out of Dispersion Analyses of Borehole Wall Displacement This article gives the theoretical background and develops a new method to determine rock-physical parameters out of such controlled measurements of waves carried inside the borehole. Theoretical dispersion curves of the group velocities are matched to dispersion analyses of registrations obtained

Fluid Pressure Variation in a Sedimentary Geothermal Reservoir in the North German Basin: Case Studion of geothermal electricity from low-enthalpy reservoirs. An . downhole laboratory was established in the 4.3 km deep well Groß Schönebeck with the purpose of developing appropriate stimulation methods to increase permeability of deep aquifers by enhancing or creating secondary porosity and flow p

Characterisation of Tensile Damage in Rock Samples Induced by Different Stress Paths,ompared to samples in which first damage is induced by compressive stresses, followed by tensile stresses. To quantify the effect of the compressive stresses, samples only damaged by compression are also studied. The tensile stresses cause the occurrence of an intergranular crack. When the sample is

Monitoring Fracture Propagation in a Soft Rock (Neapolitan Tuff) Using Acoustic Emissions and Digit the detachment of large blocks from the cavity roofs, walls and pillars, often a long time after the original quarry excavation has been completed. It is recognised that existing discontinuities, e.g., fractures, play an important role in the failure process by inducing local stress-concentrations
