摘要: The invention relates to a method of generating network fractures in rock formation for extraction hydrocarbon or other resource from the formation. includes steps i) enhancing natural and incipient within by injecting non-slurry aqueous solution into well under conditions suitable promoting dilation, shearing and/or hydraulic communication fractures, subsequently ii) inducing large-fracture that is with enhanced fracture plurality slurries comprising carrying fluid sequentially larger-grained granular proppants said series injection episodes.
