Experimental determination of colloid deposition rates and collision efficiencies in natural porous media

Simulation and Experimental Investigation of the Permeability Reduction due to Asphaltene Deposition in Porous Media

Colloid-facilitated Contaminant Transport in Natural Porous Media: Experimental Studies and Modelling

Mobile colloidal particles have been identified to be involved in a broad variety of environmentally relevant processes. A considerable number of these processes may have hazardous consequences. Most recently, mobile colloidal particles have been reported to be a potentially relevant transport pathway for strongly sorbing contaminants. Thereby the colloidal particles act as highly mobile contam...

Experimental Investigation on Asphaltene Deposition in Porous Media During Miscible Gas Injection

In this work the likelihood of asphaltene deposition problems during dynamic displacement of oil by natural gas in unconsolidated porous media is experimentally inspected. The two different rock materials, limestone and sandstone, are used as a representative of porous media. Dynamic flow experiments indicate that the increase of natural gas injection inc...

Colloid-Facilitated Solute Transport in Variably Saturated Porous Media: Numerical Model and Experimental Verification

Strongly sorbing chemicals (e.g., heavy metals, radionuclides, pharmaceuticals, and explosives) in porous media are associated predominantly with the solid phase, which is commonly assumed to be stationary. However, recent fieldand laboratory-scale observations have shown that in the presence of mobile colloidal particles (e.g., microbes, humic substances, clays, and metal oxides), colloids can...
