^bdenoted as “UA sand data” in Figure 2

^cdenoted as “UFL data” in Figure 2

^dthis study was conducted using the surfactant mass balance method under drainage conditions; all other studies employed the advective tracer-test method with the organic liquid at residual saturation (imbibition conditions).
