Nowadays hydraulic fracturing is performed for not only competent rocks but also unconsolidated sand. In the latter case, pore pressure should play a key role on fracture initiation and propagation, while the role is still unclear. Thus we examined the fracturing phenomena in laboratory experiments, and observed peculiar phenomena such as the drastic change in fracture patterns by injection flow rate and the fracturing suppression caused by slight change in formation permeability.
