摘要：
Lightweight proppant particles are disclosed. The lightweight proppant particle can include a proppant particle having an apparent specific gravity of at least about 1.5 g/cc, a coating of a hydrophobic material formed on an outer surface of the proppant particle, and a coating of an amphiphilic material formed on an outer surface of the coating of the hydrophobic material.
