In this study, the effect of brine salinity in different sequences of core flooding scenarios has been studied. Salinity of injection brines at secondary and tertiary stages of flooding has been changed to investigate low salinity effect. Core plugs from Tor chalk formation in the Danish North Sea were used and the recovery response measured by core flooding experiments. The experiments have been conducted in small scale core flooding setup, employing shorter core plugs of 1-2 cm length. As small slices with length of less than 2 cm and standard diameter are used in these experiments, the pore volume is more than 2.5 times less than the standard core plugs. Hence the amount of materials (oil and brine) and also consumption time is lower than the long core flooding experiments. Ion analysis has been conducted for effluents to see engaged mechanisms as well. This study demonstrates using small slices in core flooding experiments provides comparable results to experiments on standard cores.
