  • Scientists develop a well-good way to extract oil

    Science & Technology Facilities Council , 3rd Apr 2019

    The surfactant developed by the team from Swansea University is hydrocarbon-based, which they hope has the potential to be a ‘green’ replacement. To find out, the team, led by Dr Shirin Alexander and Professor Andrew R Barron, turned to the investigative powers of the ISIS Neutron and Muon Source at Rutherford Appleton Laboratory.

  • Scientists develop a well-good way to extract oil

    ISIS Neutron and Muon Science , 2nd Apr 2019

    Scientists from Swansea University have used ISIS Neutron and Muon Source to investigate a new and, potentially, ‘greener’ way to extract oil that might otherwise remain trapped deep within rocks.

  • Swansea University: A New Class of Branched Single Chain Surfactant for Enhanced Oil Recovery Reported

    Market Screener , 29th Mar 2019

    The researchers led by Dr Shirin Alexander and Professor Andrew R. Barron reported their find in the American Chemical Society journal of Energy & Fuels:

    Fabrication of a glass micromodel and testing of these materials were carried out by Sajad Kiani, (a PhD student at the Energy Safety Research Institute (ESRI) at the Swansea University Bay Campus).

    Sajad designed a quasi-two-dimensional glass microfluidic pattern with heterogeneous form to evaluate the suitability of the surfactant for oil displacing in EOR. Such heterogeneous pattern was replicated from a cross-section of sandstone rock and has been used to investigate the visual mechanism of the fluid flow on porous mediums.

  • A New Class of Branched Single Chain Surfactant for Enhanced Oil Recovery Reported

    EurekAlert! , 28th Mar 2019

    This efficient surfactant was examined by a research team led by Dr Shirin Alexander and Professor Andrew R. Barron at ESRI, Swansea University. It is shown to improve the oil recovery by 72% in both low and high brine solutions, a remarkable result for only a single chain surfactant flooding, compared to 45% recovery in the presence of other surfactants alone.

  • A New Class of Branched Single Chain Surfactant for Enhanced Oil Recovery Reported

    Phys.Org , 28th Mar 2019

    Dr. Alexander said: "It is a revelation that a single chain surfactant alone, without addition of any nanoparticle, polymer or alkaline, can achieve such a large recovery of oil. The effectiveness of this surfactant in EOR is due to its ability in reducing the surface and interfacial tension of the water/oil remarkably, compared to the other single chain surfactants. This is also because of its effective wettability alteration and capability to maintain the aggregation structure under extreme heat and salinity."
