Effects of Replica Ceramic Foam Microstructure on Porous Media Combustion Temperature Distribution

Simulation of Foam Transport in Porous Media

FOllin is an excellent fluid for achieving mobility control of gas in porous media. Practical application of fOllins for EOR processes, however requires a predictive model of foam displacement. Further, quantitative information on fOllin-flow behavior at reservoir flow rates llild pressures is required as input to llily field-scale modeling. An experimental and mechanistic-modeling study is rep...

Effect of Foam on Liquid Phase Mobility in Porous Media

We investigate the validity of the assumption that foam in porous media reduces the mobility of gas phase only and does not impact the liquid-phase mobility. The foam is generated by simultaneous injection of nitrogen gas and a surfactant solution into sandstone cores and its strength is varied by changing surfactant type and concentration. We find, indeed, that the effect of foam on liquid-pha...

Microstructure Analysis of Reconstructed Porous Media

We compare the quantitative microstructural properties of Berea Sandstone with stochastic reconstructions of the same sandstone. The comparison is based on local porosity theory. The reconstructions employ Fourier space ltering of Gaussian random elds and match the average porosity and two-point correlation function of the experimental model. Connectivity properties of the stochastic models dii...

Distributed Microstructure Models of Porous Media

Laminar flow through through fissured or otherwise highly inhomogeneous media leads to very singular initial-boundary-value problems for equations with rapidly oscillating coefficients. The limiting case (by homogenization) is a continuous distribution of model cells which represent a valid approximation of the finite (singular) case, and we survey some recent results on the theory of such syst...
