Discrete Element Analysis for Hydraulic Fracture Propagations in Laminated Reservoirs with Complex Initial Joint Properties

Figure 4

Interactions between the induced fracture and the preexisting fracture under the variation of pressure difference and approach angle. (In the upper right corner of each picture, those two numbers represent approach angle and the deviatoric stress. Red color represents the hydraulic fracture while black line represents the preexisting fracture. For the interpretation of the references to color in this figure, the reader needs to refer to the web version of this article).
