摘要：
Methods of initiating a fracture tip screenout, that comprise pumping an annulus fluid into an annulus, between the subterranean formation and a work string disposed within a wellbore penetrating the subterranean formation, at an annulus flow rate; and reducing the annulus flow rate below a fracture initiation flow point so that the fracture tip screenout is initiated in the one or more fractures in the subterranean formation, are provided. Also provided are methods of fracturing a portion of a subterranean formation and methods of estimating a fracture initiation flow point.
