Abstract: Based on laboratory experiments and numerical modelling, the propagation of hydraulic fracturing fractures in cylindrical granite samples caused by viscous fluid pumping is described. Comparison of simulation results and laboratory measurements show that the fracture hydraulic resistance much greater than the one predicted by the cubic law that is usually used in hydraulic fracture models. If this hydraulic resistance is not taken into account, the pressure, volume and speed of fracture propagation are predicted incorrectly. It is shown that additional hydraulic resistance can be caused by the fracture walls roughness and can be taken into account by velocity correction factor.
