Description: Wettability is the most important property governing oil trapping or recovery during water flooding in oil reservoirs. However, the wettability changes under two-phase flow in complex porous media are not well understood and the protocols of wetting state measurements are not properly defined under two phase flow conditions. Measurements of the contact angle on a substrate or the wettability index in spontaneous imbibition and centrifuge experiments do not provide a good predictability of the possible optimal wettability conditions or wettability changes in a dynamic two phase flow experiment.
We propose to study changes of oil distribution and evolution of wettability in two phase flow in glass micro-models or lab-on-chip microfluidics. The focus will be to understand oil trapping in channels and pores at different conditions. The evolution of wettability together with the distribution of oil and water versus time will be monitored. The learning from these fundamental and simplified experiments will be extended to two phase flow experiments in complex micromodels. (Text: Courtesy of Hamid Hosseinzade Khanamiri)
Deliverables: Elucidation and determination of the role of wettability in determining the macroscopic flow properties. A new method for wettability classification and determination. Experimental verification of ensemble probability distribution.
