Claim:
1. A method of treating a subterranean formation, the method comprising: providing a pad fluid comprising a tackifier and a first proppant, wherein the first proppant comprises a particle size of 150 mesh or smaller, and wherein the tackifier is at least partially coated on the first proppant, the pad fluid having a viscosity of less than about 20 cP at standard temperature and pressure; fracturing the subterranean formation with the pad fluid and at least partially coating one or more fracture face with the tackifier; providing a second fluid comprising a second proppant, wherein the second proppant comprises a particle size larger than the first proppant; and placing the second fluid in fractures and fracture branches created in the subterranean formation by the pad fluid at a pressure greater than the fracture gradient of the subterranean formation.
