Abstract
Methods comprising first introducing a solids-free fracturing fluid into a subterranean formation at a rate sufficient to enhance or create at least one fracture therein. Once a fracture is created or enhanced, a treatment fluid comprising a carrier fluid and a shear-thickening fluid is placed into the fracture. The shear-thickening fluid comprises a propping material selected from the group consisting of: proppant, proppant aggregates, solids free gel bodies, and combinations thereof. The propping material forms a bed within the fracture. In some embodiments, solids-free gel bodies may also be included in the treatment fluid.
