Diluting SW twice (d2SW) was not useful in the second cycle of core B35 as in B31 with SW. Diluting SW ten times (d10SW) triggered the B45 core's wettability to be more waterwet and to release more oil out the core (about 1.5%) making the total oil recovery from both foam and d10SW around 6.6% of the OOIP. Interestingly, lowering the injected water salinity to 966 ppm increased oil recovery in the second cycle of the core B47 to 12.5% of the OOIP, which represents the highest oil recovery in the second cycle in this study. An oil recovery of 12.5% is a high oil recovery, which was accolmlished by the effect of both foam and LS water flooding.
