Use of a gamma ray attenuation technique to study colloid deposition in porous media

Use of a gamma ray attenuation technique to study colloid deposition in porous media An experimental study of colloidal deposition in porous media is presented. The local deposition is determined through a local measurement of porosity variation using a γ-ray attenuation technique. The basic principle of this technique is described and the accuracy measurement is discussed. An experimental setup was designed using an artificial porous medium flushed with several pore volumes of a latex suspension. The damage to the porous medium was determined from permeability reduction and porosity measurements. A good agreement was obtained for a monolayer deposit. The discrepancy between global and local measurements of multilayer deposition is discussed. Experiments in Fluids Springer Journals
