Abstract

Summary

Low salinity waterflooding (LSW) is a promising enhanced oil recovery (EOR) method in which the injected brine salinity is adjusted to improve oil recovery compared to conventional high salinity waterflooding. Most of the suggested salinity values for LSW in the literature are below 5000 ppm, total dissolved solids, however, under a constant injected brine salinity, different ionic compositions of the injected water may have different effects on oil recovery. Therefore, in the present study, two mono-dimensional flow homogeneous reservoir-scale numerical models were generated to investigate the impact of injected water ionic composition on oil recovery in both sandstone and carbonate reservoirs. Based on the outcome of the simulation studies, the effect of each studied ion on oil recovery is classified into negligible, slight, significant, or key categories. Thus, it is useful for designing the injection fluid, i.e. determining which ions should enrich fresh water to obtain an effective LSW.

As a final remark, simulation results obtained in this work cannot be regarded as values of general validity because they depend on the characteristics assigned to the reservoir models. Nevertheless, the study proves the need to model and economically evaluate the injected water ionic composition for oil recovery optimization.
