摘要

Problem statement: We present an experimental study of multiphase transport in porous media with controlled wettability patterns based on lab-on-chip methodology. Approach: Fractional, or patterned, wettability was known to have an enormous impact in the petroleum industry on oil recovery and continuous efforts are being made to assess the role of such conditions. Results: Thus far, due to the absence of the technology required to produce micro fluidic networks modeling porous media (called "micromodels") with well-controlled wettability patterns, experimental results on this question have remained particularly elusive. We recently unlocked this bottleneck and can now selectively alter surface wettability within individual pores and thereby create precisely controlled wettability patterns within "micro models". Conclusion/Recommendations: The experiments we report here reveal the considerable impact of wettability patterning on the oil-water flow behavior (as compared with homogeneous wetting) and consequence on the amount of liquid left after one phase has been swept through the network, information directly linked to the question of oil recovery.
