Conformance Control through In-situ Gelation of Silica Nanoparticles

Rankin K.M., Nguyen Q.P., The University of Texas at Austin, US

Due to reservoir heterogeneities, oil recovery from fluid injection during secondary and/or tertiary recovery does not occur in an ideal piston-like displacement. Rather sweep efficiency can be much lower than 100% due to heterogeneities such [...]

Molecular dynamics simulation of the transport of H2, O2, Ar, CH4 and n-C4H10 in composite poly (4-methyl-2-pentyne) and nanoparticle of cristobalite silica and faujasite silica

Yang Q., Achenie L.E., Virginia Tech, US

In industrial processes membranes made of composite polymer material are widely employed to separate gas mixtures. These membranes have better performance than membranes consisting of polymer alone. To understand the mechanism and therefore aid membrane [...]

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. [...]

Liposome Encapsulation of Fluorescent Nanoparticles: Quantum Dots and Silica Nanoparticles

Chen C-S, Yao J., Durst R.A., Cornell University, US

Quantum dots (QDs) and silica nanoparticles (SNs) are new classes of fluorescent probes that overcome the limitations encountered by organic fluorophores in bioassay and biological imaging applications. We encapsulated QDs and SNs into liposomes by [...]
