- who: Amir H. Haghi from the DepartmentUniversity of have published the Article: Poromechanical controls on spontaneous imbibition in earth materials, in the Journal: Scientific Reports Scientific Reports of 23/Nov/2020
- what: The authors designed the experiments such that fluid-fluid displacements are capillary-dominant (i.e., spontaneous) imbibition with capillary numbers in the order of Ca=(µw vw )/γ ≈ 10-8, where γ is the interfacial tension, vw is the interstitial water velocity vw=Qw /(ϕA), and ϕ is the porosity of the r ock33. These observations quantify the striking impact of poromechanics on fluid-fluid displacement . . .
