Report on the laboratory fracking experiment, its boundary conditions, and ist flow rates and fracture apertures versus time curves.

Report on the laboratory fracking experiment performed at controlled conditions (state of stress, flow rate and pressure, laboratory pressure and temperature) on sample blocks of size 30x30x45 cm³, its boundary conditions, and its flow rates and fracture apertures versus time curves. Results of this experiment will be used in task 6.5 for verifying a selection of numerical codes for simulating the propagation of hydraulic fractures.
