Certain embodiments of the present disclosure are directed to techniques for creating a filler material within a slickwater slurry. The filler material is generated by adding a cationic additive to the slickwater slurry. The cationic additive can be introduced to the slurry either before, after, or simultaneously with the proppant or friction reducer. Upon addition and mixing with the friction reducer, the cationic additive reacts due to electrostatic attraction, forming gel-like substances or agglomerates. This process, which may be termed complex coacervation, agglomeration, or aggregation, may entrap proppant particles during formation, with proppant particles possibly being trapped within these agglomerates or aggregates. The operation then proceeds as a slickwater treatment. After the proppant is delivered into the fracture and subsequently transported and settled, the agglomerates act as fillers within the proppant pack, thereby reducing its bulk density.

For example, a method includes 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; and 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.
A system and method are provided for stimulating heterogeneous subterranean formations using a tailored particulate diverter (PD). In some embodiments, a wellbore completion string includes an inflow control device (ICD) positioned in a high-permeability zone and an additional completion section positioned in a lower-permeability zone. The ICD includes restrictive openings, such as nozzles or valves, configured to impose a predictable pressure drop to balance inflow during production. During stimulation, the tailored particulate diverter comprising degradable diverter particles suspended in a carrier fluid is pumped into the completion string. The diverter particles exhibit a multimodal particle size distribution with at least four distinct size modes selected to bridge and seal the restrictive openings of the ICD, diverting stimulation fluid into the lower-permeability zone. Following treatment, the diverter particles degrade under downhole conditions to restore flow through the restrictive openings, improving stimulation coverage and enhancing overall production and/or injection efficiency.
