摘要： Dual-purpose additives that may be used as viscosifying agents and surface active agents in fluids, subterranean treatments and oilfield operations are provided. In one embodiment, the methods comprise: providing a treatment fluid comprising a base fluid and a polymeric dual-purpose additive comprising a base polymer comprising a plurality of monomer units, and one or more hydrophobic groups bonded to at least one of the monomer units; introducing the treatment fluid into at least a portion of a subterranean formation; and depolymerizing at least a portion of the dual-purpose additive to form one or more surface active fragments, each of the surface active fragments comprising one or more of the hydrophobic groups bonded to one or more of the monomer units.

摘要： Methods involving the sequential application of surfactants to improve fluid recovery and control fluid loss in conjunction with subterranean fracturing treatments are provided. In one embodiment, the methods comprise: introducing a first surfactant into a portion of a subterranean formation; allowing the first surfactant to increase the oil-wettability of at least a portion of a fracture face in the portion of the subterranean formation; ceasing the introduction of the first surfactant into the portion of the subterranean formation; introducing a second surfactant into the portion of the subterranean formation; and allowing the second surfactant to increase the water-wettability of the portion of the fracture face in the portion of the subterranean formation.
