A multiscale analysis of a fracture pattern in granite: A case study of the Tamariu granite, Catalunya, Spain

摘要: The in-depth investigation of fractured reservoirs is mainly limited to geophysical data that in 3D and mostly on the scale hundred meters several kilometers or boreholes 1D at meter lower scale. study outcropping analogues buried therefore a key tool for characterization fault fracture network reservoir Tamariu granite has been subject this with aim analyse faults fractures from seismic borehole With combination satellite picture different resolution field study, we perform statistical analysis focused length orientation infra centimeter crack kilometer fault. On whole range studied, i.e. 7 orders magnitude, have defined distribution following power-law an exponent = -2. contrary can be modelled unique law, shows variation depending observation: as sets are suitable regional crack, proportion varies each observation.
