267 These experiments in the following example involve the CO
invasion of a vertical, brine-
2
saturated Berea sandstone core (1,010 mD, 22% porosity, 40 mm x 170 mm, 20–30 micron pore
throat diameters) [Farajzadeh , Andrianov, Bruining and Zitha, 2009]. In the “base case” of the
following example, there is no surfactant in the brine, thus fingering and early gas breakthrough
would be expected. This is shown in the top series of CT images in Figure 10.4, where there is
not a distinct CO
front displacing the brine and breakthrough occurs after injection of ~0.18 PV
2
of CO
due to fingering. The lower series of CT images illustrates the effect of saturating the
2
core with a surfactant solution; a sharp CO
front forms, fingering is inhibited, and CO
2
2
breakthrough does not occur until ~0.45 PV of CO
are injected.

Andrianov, Bruining and Zitha, 2009]
