Capillary imbibition recovery was studied considering the simultaneous effects of gravity, low interfacial tension (IFT), and boundary conditions. Kerosene and light crude oil were used. Berea Sandstone samples saturated with two-types of oil were exposed to counter- and co-current capillary imbibition at ambient temperature and pressure conditions. For kerosene-brine pair, no significant change in the ultimate recovery with different boundary condition (BC) was observed. However, for crude oil-brine pair, the BC affected the ultimate recovery. The low IFT solution yields in higher oil recovery from the non-contacted part of the core sample was observed. However, the recovery rate decreased when the low IFT solutions was used instead of brine especially for the unfavorable boundary conditions.
