We
present the results of an experimental investigation of the
effect of gas type and composition on foam transport in porous media.
Steady-state foam strengths with respect to three cases of distinct
gases and two cases containing binary mixtures of these gases were
compared. The effects of gas solubility, the stability of lamellae,
and the gas diffusion rate across the lamellae were examined. Our
experimental results showed that the steady-state foam strength is
inversely correlated with the gas permeability across a liquid lamella,
a parameter that characterizes the rate of mass transport. The results
are also in good agreement with existing observations that the foam
strength for a mixture of gases is correlated with the less soluble
component. Three hypotheses with different predictions of the underlying
mechanism that explain the role of gas type and composition in foam
strength are discussed in detail.
