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.
Claims6
A method of hydraulic fracturing comprising
- formulating a hydraulic fracturing fluid comprising:
- a liquid solvent comprising seawater;
- at least one surfactant comprising an alkoxylate based surfactant and an ethoxylated isotridecanol based surfactant;
- a liquid phase proppant-forming compound comprising a modified bisphenol A epoxy resin;
- at least one curing agent comprising an amine modified curing agent;
- and
- injecting the hydraulic fracturing fluid into a wellbore;
- generating a product of agglomerated individual solid beads from the alkoxylate based surfactant and the ethoxylated isotridecanol based surfactant in the hydraulic fracturing fluid in-situ under down hole conditions;
- and
- forming pillars from islands generated by the product of in-situ formed agglomerated individual solid beads in a two-dimensional structure capable of maintaining conductive fractures in a downhole environment.
