Furthermore, if AE occurs during the mini-frac test, its spatio-temporal hypocenter distribution could help to estimate the dynamic behaviors of fracture extension or pressure diffusion. However, a relationship between the spatio-temporal hypocenter distribution...

... ABSTRACT Our previous studies on hydraulic fracturing in granite at 200°C to 450°C under triaxial stress condition revealed that infiltration of low-viscosity water at near-/super-critical temperatures stimulates preexisting microfractures and creates dense fracture networks which is favorable...

... and project economics of unconventional field development are highly dependent on the effectiveness of hydraulic fracturing. The mechanism of hydraulic fracturing is complicated due to interference between the multiple factors. Not only the geological heterogeneities such as natural fractures but also...

... to natural fracture system. For the construction of a quantitative geomechanical model, a hydraulic fracturing simulator, which can model a primary tensile fracture propagation interacting with a natural fracture system, is used. The most difficult parameters to estimate are properties of a natural fracture...

... Abstract A hydraulic fracturing simulator for modeling a primary tensile fracture propagation interacting with a natural fracture system has been developed. In the simulator, the primary fracture is modeled by small segments aligned along the direction of maximum horizontal stress...
