Summary: | A hydraulic fracturing method is disclosed that includes designing a fracture treatment including a fluid pumping schedule to fracture a subterranean formation according to a design model that accounts for cumulative filter cake thickness, including polymer concentrated at the fracture surfaces, to provide a propped fracture width effectively greater than the cumulative filter cake thickness, and injecting fluids through a wellbore into the formation essentially according to the fluid pumping schedule of the fracture treatment design. A fracturing method is also disclosed that includes placing a high breaker loading in the filter cake. A composition is disclosed which comprises a fluid viscosified with a polymer and a fluid loss additive comprising a delayed breaker. |
