Abstract
A method for generating self-propped hydraulic fractures. In one embodiment, the method comprises injecting three fluid stages sequentially, each with successively higher viscosity, comprising a pad, a sealing slurry, and a displacement fluid which may be referred to as a sweep. Compositions of each of the three fluid stages are provided, each of which may be selected based upon characteristics of the formation being treated or upon one or more characteristics of the desired fracture.
