Claim 0:
1. A method associated with a chemical composition for fracturing fluids to increase estimated ultimate recovery of hydrocarbons from shale, the method comprising:
pumping the chemical composition within a fracture, the chemical composition including an ammonium chloride corrosion inhibitor, a phosphonate scale inhibitor, and a surfactant, wherein the ammonium chloride corrosion inhibitor is alkyl pyridine quaternary ammonium chloride;
pumping a proppant pack within the fracture, wherein the proppant pack is pumped downhole with the chemical composition, the proppant pack including an anionic charged proppant;
forming a film on pyrite on the shale within the fracture and forming a film on the proppant pack, the film causing the proppant to be hydrophobic;
changing a relative permeability of the proppant pack to reduce an amount of water flowing through the proppant pack while allowing viscous oil to flow through the proppant pack, wherein the surfactant lowers the relative permeability of the proppant pack;
reducing a flow of water from a fracture towards a surface of a well via the proppant pack.
