.... The premature sreenout is caused by insufficient fracture growth and inadequate fracture aperture to accept certain amount of proppant concentration. The causes are roughly classified into three types. The first one is near fracture plane twisting or discontinuity which is known as nearwellbore tortuosity...

... simulator incorporates pressure-dependent apertures of the primary fracture as well as the natural fractures by converting their apertures to hydraulic properties of dual porosity model at each time step. Using the developed simulator, we investigate effects of horizontal stress contrast and degree...
