Abstract:
Polymer and low salinity flooding can improve the oil recovery from both sandstone and carbonate reservoirs. Combining these methods is of interest because they can improve both macroscopic and microscopic sweep efficiency, and the required polymer volume becomes less when mixed with low salinity brine, which has a positive impact on both cost and environment. However, as polymer molecules are large compared to the ions in the brine and even large compared to the typical pore sizes, the polymer molecules may flow at a completely different speed than the salt ions. This could be of particular importance in highly inhomogeneous systems.
