Isolation of haloarchaea that grow at low salinities
Environmental Microbiology, 2004Summary Archaea, the third domain of life, were long thought to be limited to environmental extremes. However, the discovery of archaeal 16S rRNA gene sequences in water, sediment and soil samples has called into question the notion of Archaea as obligate extremophiles.

The extension of the Practical Salinity Scale 1978 to low salinities
IEEE Journal of Oceanic Engineering, 1986The Practical Salinity Scale (PSS) 1978 is defined only for salinities within the range 2-42. We have investigated the relationship between mass-determined salinity, electrical conductivity, and temperature for salinities between 0 and 2 with the aim of developing an extension to the Practical Salinity Scale 1978.

Novel Observations of Salinity Transport in Low-Salinity Waterflooding
SPE Journal, 2019Summary Low-salinity waterflooding (LSWF) is a promising process that could lead to increased oil recovery. To date, the greatest attention has been paid to the complex oil/water/rock chemical reactions that might explain the mechanisms of LSWF, and it is generally accepted that these result in behavior equivalent to changing oil and ...

One of the key open questions in the area of low or controlled salinity water flooding (LSWF or CSWF) is how the observed oil recovery at macro-scale (e.g. Darcy or core-scale) can the explained and what underlying microscopic mechanisms drive it.

Under‐ice salinity transport in low‐salinity waterbodies
Limnology and Oceanography, 2019AbstractIn cold and temperate climates, ice typically covers the surface of waterbodies during winter. Many of these systems are also weakly saline where, unlike seawater, the temperature of maximum density, , is higher than its freezing temperature, .

Although the terms Low Salinity Sea Water and Smart Sea Water have been used interchangeably as one of Enhanced Oil Recovery methods in recent years, the present study shows that there are some differences between these two.

Visualizing Low-Salinity Waterflooding
Journal of Petroleum Technology, 2014Technology Update Low-salinity waterflooding has recently attracted considerable interest from governments, researchers, and oil companies, who are evaluating the method’s potential to increase oil recovery. While laboratory work and field tests have indicated that low-salinity waterflooding can have positive results, and implementation ...

Low Salinity EOR in Carbonates
SPE Improved Oil Recovery Symposium, 2012Abstract Modifying the chemistry of injection water yields improved wettability behavior on carbonate rock surfaces. Previous work has focused on demonstrating the effect of modified brine formulation on particular carbonate samples. Here the results of a more general screening study consisting of Amott spontaneous imbibition experiments

Low salinity waterflooding has received increasing attention. However, the increased oil recovery by low salinity is in most cases very limited. Combining low salinity with other EOR methods has been our focus in recent years. The combined effect of brine chemistry and added surfactant on oil recovery was addressed by Alagic and Skauge in recent ...
