Patent ID: 8327940

Claim:
A method for hydraulic fracturing of a low-permeability subterranean formation comprising injecting a fracturing fluid with a pumping rate exceeding 8 m 3 /min through a wellbore into a fracture made in the subterranean formation, the fracturing fluid having viscosity less than 0.01 Pa·s and containing proppant particles with the radius σ, which is determined by formula σ < 0.0173 ⁢ w ⁢ ρ f ρ p if proppant particles are heavier than the fracturing fluid (ρ p >ρ f ), or by formula σ > 0.0387 ⁢ w ⁢ ρ f ρ p if proppant particles are lighter than the fracturing fluid (ρ p <ρ f ), where w is the fracture width, ρ f and ρ p —densities of the fluid and proppant.
