Abstract

The invention includes a method of extending an oil and gas system effective stimulated reservoir volume by performing the steps of adding a brine resistant silicon dioxide nanoparticle dispersion to oil well treatment fluids. This method is found to increase initial production rates of an oil well by over 20.0% as compared to wells either not treated with the brine resistant silicon dioxide nanoparticle dispersion technology or treated by conventional nano-emulsion surfactants.
