... acting as barriers to the growth. Preliminary modeling results show how the vertical growth of a hydraulic fracture is influenced by the various mechanical/energy barriers. Three primary types of barrier behaviors are identified. A stress barrier leads to gradually increasing fluid pressure when...

... the opposite side. Continuous three-dimensional growth of the hydraulic fracture increases the fluid pressure inside the open natural fracture and can cause initiation of a branch fracture from one or more of its extremities. The net result is creation of a main fracture together with a set of smaller and very...

... hydraulic fractures and natural fractures are represented in a unified framework by split interfaces between solid elements that represent the rock continuum. Fracture flow elements and frictional contacts are deployed along the split interface, generating fluid pressure and contact stress applied...

.... In this application of the equations, the internal wellbore fluid pressure is assumed to be applied to the surface of the borehole, without penetration into the pore space of the rock. Breakdown of the well is assumed to occur when the internal wellbore pressure is high enough to set the tangential stress (σ t...
