Understanding the Mechanisms of Low-Salinity Flooding in Carbonates using Model Systems

Low-salinity flooding (LSF) is an improved-oil-recovery method that consists of injecting brine with lower salinity than conventional formation water into the reservoir rock. This method has the potential to improve the oil recovery beyond conventional waterflooding. In sandstone reservoir rocks, it has been reported that the salinity range...

Calcite dissolution behaviour during low salinity water flooding in carbonate rock

Low salinity water flooding (LSF) has been proved to be a promising enhanced oil recovery method for sandstone reservoirs. The efficiency of LSF in carbonate reservoirs has not been proven completely yet, because there are still uncertainties about the LSF recovery mechanism in carbonate. From experimental studies, it was shown that wettability...
