Systems and methods for facilitating effective fracture initiation

A method comprising:

• deploying a tool string into a wellbore extending through a subterranean formation, wherein the tool string comprises a perforating tool and a mechanical reactant delivery assembly;
• releasing a plurality of chemical reactants from the mechanical reactant delivery assembly while the tool string is deployed within the wellbore to enable the plurality of chemical reactants to mix to form a breakdown fluid;
• firing one or more explosive charges of the perforating tool to inject the breakdown fluid into the subterranean formation to initiate one or more fractures in the subterranean formation;
• and
• pumping a follow-up fluid into the subterranean formation subsequent to injecting the breakdown fluid into the subterranean formation,
• wherein the breakdown fluid is configured to produce a gel having a viscosity higher than the follow-up fluid, and
• wherein the follow-up fluid comprises a crosslinking agent configured to continue to gel the breakdown fluid in the subterranean formation.
