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.;;;;;;;;;;;;;
