    摘要: Methods of improving load recovery using hydrophobic coatings to enhance the recovery of treatment fluids from subterranean formations may include the use of hydrophobic coating agents. In particular, such methods may include the steps of coating a plurality of particulates so as to form a plurality of hydrophobically-coated particulates. The presence of these hydrophobically-coated particulates downhole may enhance the recovery of aqueous treatment fluids.
