Scientists at the Siberian Federal University are studying the effect of nano-additives on the properties of gels used in hydraulic fracturing (FRACKING).
Studies have shown that silicon oxide nanoparticles significantly improve parameters such as wettability and interfacial tension.
The use of nanoparticles in low concentrations (from 0.01%) makes it possible to accelerate the penetration of the gel into the formation, and higher concentrations (up to 0.8%) increase its viscosity. These data will help optimize the composition of gels for various mining conditions. In addition, the addition of nanoparticles increases the thermal stability of gels.
The results of laboratory studies are planned to be tested on real deposits. If the technology proves its effectiveness, nanoparticles can replace expensive chemical additives, reducing the cost of the process.
