    • A theoretical study of gas adsorption on calcite for CO2 enhanced natural gas recovery 

      Carchini G.; Hussein I.; Al-Marri M.J.; Shawabkeh R.; Aparicio S. ( European Association of Geoscientists and Engineers, EAGE , 2019 , Conference Paper)
      The adsorption of gas molecules (CO2, CH4, H2O, H2S and N2) on calcite (104) has been studied by means of Density Functional Theory, in order to investigate the molecular characterization of Enhanced Gas Recovery (EGR) ...

    • Application of DFT in iron sulfide scale removal from oil and gas wells 

      Onawole A.; Hussein I.; Saad M.; Ahmed M.; Aparicio S. ( European Association of Geoscientists and Engineers, EAGE , 2019 , Conference Paper)
      Scale formation including those formed by iron sulfides have been a major hassle in the upstream sector of the oil and gas industry for many decades. Iron Sulfide scales including pyrite (FeS2) and troilite (FeS) often ...
