Interaction of Surface Modified Silica Nanoparticles with Clay Minerals

Metin C.O., Nguyen Q.P., The University of Texas at Austin, US

The interaction of silica nanoparticles with montmorillonite clay was investigated by visual swelling tests, Fourier Transform Infrared (FTIR), and x-ray diffraction (XRD). The adsorption of silica nanoparticles onto montmorillonite was also studied with a UV-Vis [...]

The Retention of Silica Nanoparticles at Oil/Water Interface

Metin C.O., Nguyen Q.P., The University of Texas at Austin, US

We investigate the retention of silica nanoparticles at water/crude oil interface. Silica nanoparticles with three different surfaces (unmodified, surface modified with anionic (sulfonate), or nonionic (PEG) surfactant) are used. Interfacial tension (IFT) measurements provide us [...]

Stability of Aqueous Silica Nanoparticle Dispersions under Subsurface Conditions

Metin C.O., Nguyen Q.P., Lake L.W., The University of Texas at Austin, US

The potential application of nanotechnology has significantly advanced into the upstream oil and gas industry. However, harsh subsurface conditions such as high temperature and saline environment are generally incompatible to most commercially available engineered nanoparticles. [...]
