Aqueous foams play an important role in many industrial processes, from ore separation by froth flotation to enhanced oil recovery (EOR). In the latter case, the foam is used as a means of increasing the sweep efficiency through the oil bearing rock -the complex, structure dependent, flow behaviour of the foam [Jones et al., 2013] means that it has improved penetration of lower permeability regions than would be obtained with a Newtonian fluid. An understanding of how foam behaves when flowing through a rock is therefore of great importance when selecting suitable surfactants for EOR processes.Previous tests have suggested that there is no reliable correlation between bulk foam behavior and foam behavior in a rock core, especially in the presence of oil [Dalland et al., 1994;Mannhardt et al., 2000]. We present a comparative study of bulk stability tests and core floods with foam, both with and without oil. Core-flood tests were conducted in rock cores with a diameter of 1 cm and length of 17cm, significantly smaller than typical cores [Jones et al, 2015]. Apparent viscosity / injected gas fraction response curves were obtained, both with and without oil in the system. This current work found that there is a positive correlation between bulk foam stability and core flood performance in the absence of oil. Bulk foam experiments can therefore be a useful screening tool to get a good indication of the surfactant performance in the core flood. However, there was no correlation found between bulk foam stability and the performance in the core for the experiments performed in the presence of oil.It is crucial to select the right surfactant, as it stabilizes the foam. The surfactant selection is specific to the application; it depends of the rock chemistry, water salinity, reservoir temperature and the oil type. The general consensus is that the most representative test of the foam behavior, especially in presence of oil, is the coreflood experiment at the reservoir conditions. However coreflood tests are timedemanding and expensive so that only a limited number of surfactants can be tested. Bulk foam tests
