...) was calculated for each area and each layer. Even though the overall VRR in the waterflooded areas is above one, the distribution of the injected water is uneven. Redistributing injected water and ensuring that all the areas and all the layers are adequately supported will help to maximize recovery...

Paper Number: SPE-206151-MS
...Abstract Abstract Oil-wetness and heterogeneity (i.e., existence of low and high permeability regions) are two main factors that result in low oil recovery by waterflood in carbonate reservoirs. The injected water is likely to flow through high permeability regions and bypass the oil in low...

..., the remaining fractional oil from water-wet sandstone formations is generally less than the oil-wet formations. In water-wet sandstone formations, during waterflooding, the injected fluid tends to imbibe into the pore network due to the favorable wetting conditions. On the contrary, in naturally fractured oil...
