    • The effect of temperature on CO2 injectivity in sandstone reservoirs 

      Sokama-Neuyam, Yen Adams; Aggrey, Wilberforce N.; Boakye, Patrick; Sarkodie, Kwame; Oduro-Kwarteng, Sampson; Ursin, Jann Rune (Peer reviewed; Journal article, 2022)
      Carbon Capture, Utilization and Storage (CCUS) is a pragmatic technology that could reduce anthropogenic CO2 and halt climate change. CO2 injectivity is affected by several physicochemical interactions around the injection ...

    • Experimental and theoretical investigation of the mechanisms of drying during CO2 injection into saline reservoirs 

      Sokama-Neuyam, Yen Adams; Yusof, Muhammad Aslam Md; Owusu, Shadrack Kofi; Darkwah-Owusu, Victor; Turkson, Joshua Nsiah; Otchere, Adwoa Sampongmaa; Ursin, Jann Rune (Peer reviewed; Journal article, 2023)
      A viable CO2 storage resource must have sufficient storage capacity, reliable containment efficiency and adequate well injectivity. Deep saline formations stand out in terms of storage capacity and containment efficiency. ...

    • Experimental Investigation of the Mechanisms of Salt Precipitation during CO2 Injection in Sandstone 

      Sokama-Neuyam, Yen Adams; Ursin, Jann Rune; Boakye, Patrick (Peer reviewed; Journal article, 2019)
      Deep saline reservoirs have the highest volumetric CO2 storage potential, but drying and salt precipitation during CO2 injection could severely impair CO2 injectivity. The physical mechanisms and impact of salt precipitation, ...

    • Stochastic thermodynamic production model for shale gas reservoirs 

      Ramirez Pacheo, Carlos (Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-06-15)
      Most operating companies use Decline Curve Analysis (DCA) for their production forecast on Shale Gas assets (Mongalvy, Chaput and Agarwal, 2011). DCA method is based in empirical analysis and the theoretical background ...

    • Theoretical Modeling of the Impact of Salt Precipitation on CO2 Storage Potential in Fractured Saline Reservoirs 

      Sokama-Neuyam, Yen Adams; Boakye, Patrick; Aggrey, Wilberforce Nkrumah; Obeng, Nicholas O.; Adu-Boahene, Francis; Woo, Seung Han; Ursin, Jann Rune (Peer reviewed; Journal article, 2020)
      Deep saline reservoirs have the capacity to hold large volumes of CO2. However, apart from the high brine salinity, which poses an injectivity challenge, a high percentage of saline reservoirs are also fractured. The ...
