Rock Damage and Fluid Transport, Part II
This volume forms the second part of a topical issue generated from contributions presented at the Euroconference on Rock Physics and Geomechanics that 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 properties of fractured rocks which were studied with advanced techniques at the laboratory scale and the field scale. Elsworth and Yasuhara conduct circulation experiments on fractures in novaculite and limestone, intermittently imaged by X-ray computer tomography. Xiao et al. measure permeability, storage capacity, volumetric strain and creep during the deformation of hot-pressed calcite samples with different volume fractions of quartz. Song and Renner investigate the influence of heterogeneities on hydraulic properties of Fontainebleau sandstone applying harmonic pore pressure testing. On a larger scale, Albrecht and Mansurov estimate porosity and permeability analysing the velocity dispersion of elastic waves near boreholes. Huenges et al. monitor fluid pressure variations in a borehole sunk in geothermal reservoir rocks of the Rotliegend formation in NE-Germany.
