International Petroleum Technology Conference
Abstract The use of Low Salinity Waterflooding (LSWF) as Enhanced Oil Recovery (EOR) technique has gained attention due to its cost-effectiveness, simplicity, and environmental benefits. Existing research emphasizes the importance of injected brine salinity and Potential Determining Ions concentration in EOR, primarily in sandstone ...

Low Salinity Waterflooding and Mineral Dissolution
SPE Annual Technical Conference and Exhibition, 2010Abstract Numerous laboratory studies have shown that water composition can substantially affect oil recovery by waterflooding. Investigation of increased oil recovery by injection of low salinity water such as coalbed methane production water has been extended to reservoir cores from the Tensleep, Minnelusa and Phosphoria formations in ...

Evaluation of Mixing in Low Salinity Waterflooding
SPE EOR Conference at Oil and Gas West Asia, 2016Abstract The impact of heterogeneity induced mixing between the injected low salinity water and the high salinity connate water is investigated in secondary low salinity waterflooding (LSW). Although LSW has proved to be a promising EOR process in laboratory experiments and field trials, its efficiency can be reduced due to mixing with ...

Low Salinity Water Injection for EOR
SPE Nigeria Annual International Conference and Exhibition, 2015Abstract Low Salinity Waterflooding is one of the emerging oil recovery techniques which has gained its popularity in the past decade. Many experiments and laboratory works have been conducted since its oil recovery potential was discovered in late 1960s.
