Abstract
A hydraulic fracture fluid is provided. The fluid can include a liquid solvent, one or more surfactants, a proppant-forming compound, and one or more curing agents. The liquid reacts to form proppant in-situ under downhole conditions.
Claims18
A hydraulic fracturing fluid, comprising:
- a liquid solvent;
- at least one surfactant;
- a liquid phase proppant-forming compound, wherein the liquid phase proppant-forming compound comprises at least one of aliphatic epoxides, anhydrides, glycidyl amine epoxide, cycloaliphatic epoxides, epoxy functional resins, polyurethane resins, phenol-formaldehyde resin, bis-phenol A diglycidyl ether, poly glycidyl ethers, acrylic resin, glycidyl ethers, or bis-phenol F diglycidyl ethernovalac resins, or combinations thereof;
- and
- at least one curing agent;
- wherein a product of agglomerated individual solid beads is generated from the hydraulic fracturing fluid in-situ under downhole conditions, and wherein a ratio of an alkoxylate based surfactant and an ethoxylated isotridecanol based surfactant is changed to adjust a Hydrophile-Lipophile Balance and a coalescence rate of the agglomerated individual solid beads.
