providing a proppant-free pad or pre-pad fluid that comprises a base fluid and a surface-treating reagent capable of modifying the stress-activated reactivity of a mineral surface in a subterranean formation, wherein the surface treating reagent comprises at least one tackifying agent selected from the group consisting of a polyamide, a polyester, a polycarbonate, a polycarbamate, an acrylic acid polymer, an acrylic acid ester polymer, an acrylic acid derivative polymer, an acrylic acid homopolymer, an acrylic acid ester homopolymer, an acrylic acid ester co-polymer, a methacrylic acid derivative polymer, a methacrylic acid homopolymer, a methacrylic acid ester homopolymer, an acrylamido-methyl-propane sulfonate polymer, an acrylamido-methyl-propane sulfonate derivative polymer, an acrylamido-methyl-propane sulfonate co-polymer, an acrylic acid/acrylamido-methyl-propane sulfonate co-polymer, a silyl-modified polyamide compound, and any combination thereof;

introducing the pad or pre-pad fluid into the subterranean formation; and

allowing the surface-treating reagent to modify the stress-activated reactivity of at least a portion of the mineral surface in the subterranean formation.
