Relative permeability modifier package for produced fluids from a subterranean formation

A method of treating a portion of a subterranean formation comprising:

• introducing a fluid into the portion of the subterranean formation that has an initial permeability to an aqueous fluid, wherein the fluid comprises:
• a liquid, wherein the liquid comprises water, and wherein the water is selected from the group consisting of freshwater, seawater, brine, and any combination thereof in any proportion;
• a mutual solvent;
• and
• a relative permeability modifier package, wherein the relative permeability modifier package comprises:
• a first relative permeability modifier that is a surfactant, wherein the first relative permeability modifier is water insoluble, and wherein the first relative permeability modifier is soluble in the mutual solvent;
• and
• a second relative permeability modifier that is a polymer, wherein the polymer comprises a hydrophilic monomer and a hydrophobically modified monomer;
• and
• causing or allowing the first and second relative permeability modifiers to coat surfaces of the portion of the subterranean formation, wherein after coating, a final permeability to the aqueous fluid is reduced from the initial permeability.
