  • Publication number: 20180230362
    Abstract: A fracturing fluid comprises an aqueous base fluid and a cationic polymer combined with a salt. The fracturing fluid may be used to fracture a subterranean formation. The cationic polymer in combination with a salt provides for reduced clay swelling, while maintaining the granularity and porosity of the formation, which thereby promotes the flow of hydrocarbons from the formation.

  • Publication number: 20180134948
    Abstract: A method of treating in a subterranean formation including combining an aqueous base fluid, an oil based fluid, a hydrophobic proppant, and a non-hydrophobic proppant to form an immiscible fluid system; and introducing the immiscible fluid system into the subterranean formation. A method of treating includes combining an aqueous base fluid, an oil based fluid, a hydrophobic proppant, and a non-hydrophobic proppant to form an immiscible fluid system; introducing the immiscible fluid system into a fracture in the formation; allowing the immiscible fluid system to separate into at least two separate phases, wherein the oil based fluid and hydrophobic proppant to form proppant aggregates and the aqueous based fluid to act as a spacer fluid surrounding at least a portion of the proppant aggregates; and removing the spacer fluid from the fracture during flowback stage or well production to form proppant-free channels between proppant aggregates.
