The application discloses a method of treating a subterranean formation of a well bore, including providing a first treatment fluid substantially free of macroscopic particulates; pumping the first treatment fluid into the well bore at different pressure rates to determine the maximum matrix rate and the minimum frac rate; pumping the first treatment fluid above the minimum frac rate to initiate a fracture; providing a second treatment fluid comprising a second carrier fluid, a particulate blend including a first amount of particulates having a first average particle size between about 100 and 2000 µm and a second amount of particulates having a second average particle size between about three and twenty times smaller than the first average particle size, such that a packed volume fraction of the particulate blend exceeds 0.74; pumping the second treatment fluid below the minimum frac rate; and allowing the particulates to migrate into the fracture. |
