Therefore, it is important to better understand the interaction between injected brine and carbonate rock to de-risk...

... Abstract Wettability of the reservoir is a major parameter controlling the oil production profile during waterflooding, the breakthrough of injection water, the final oil recovery, and the residual oil saturation (S or ) trapped in the pore structure. Therefore identifying the wettability...

... Abstract Field application proves that polymer flooding is an effective technology for improving development effect of heterogeneous reservoirs. Previously, single slug injection is performed. However, there are problems of profile reverse, non-effective circulation of polymer solution in high...

It showed that suitably formulated ion tuning water (ITW) has the potential to accelerate oil production and improve displacement efficiency, thus resulting in a higher recovery factor with only a fraction of pore volume of low-salinity water injected. To conclude, this paper demonstrates that ITWF has...
