Abstract

The invention discloses a method for use in a wellbore in a tight gas shale formation, comprising: providing a hydraulic fracturing fluid to initiate at least a fracture in the shale; injecting a treatment fluid in the fracture to at least partially destabilize and remove the shale; and repeating the step of fracturing the shale.
