2. 1. CO2 storage in deep saline aquifers : Models for geological heterogeneity and large domains

   Author : Liang Tian; Auli Niemi; Fritjof Fagerlund; Simon Mathias; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; CO2; Carbon Capture Storage; Storage Capacity; Injectivity; Monte Carlo; Gaussian; Permeability; Upscaling; 二氧化碳; 地質封存; 高斯仿真; 滲透係數; 非均質性; 升尺度; 存儲效能; 場地模擬; 不確定性; 壓力累積;

   Abstract : This work presents model development and model analyses of CO2 storage in deep saline aquifers. The goal has been two-fold, firstly to develop models and address the system behaviour under geological heterogeneity, second to tackle the issues related to problem scale as modelling of the CO2 storage systems can become prohibitively complex when large systems are considered.

4. 2. Residual Trapping in Geological Storage of CO2 : Determination from Field Experiments and Data Analysis Using Numerical Modeling

   Author : Saba Joodaki; Auli Niemi; Zhibing Yang; Jonathan Ennis-King; Uppsala universitet; []
   Keywords : Residual trapping; CO2 geological storage; Dissolution trapping; Field experiment; numerical modeling; Geovetenskap med inriktning mot miljöanalys; Earth Science with specialization in Environmental Analysis;

   Abstract : Geological storage of CO2 in deep saline aquifers is one of the methods to mitigate the release of this greenhouse gas into the atmosphere. The efficiency of this solution can be improved by better understanding of the relevant trapping processes, as well as by improving available injection techniques and developing tools for more accurate site characterization.

5. 3. Residual and Solubility trapping during Geological CO2 storage : Numerical and Experimental studies

   Author : Maria Rasmusson; Fritjof Fagerlund; Auli Niemi; Jonathan Ennis-King; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; capillary trapping; CCS; convective flow; CO2; light transmission; SO2; well test; Hydrology; Hydrologi;

   Abstract : Geological storage of carbon dioxide (CO2) in deep saline aquifers mitigates atmospheric release of greenhouse gases. To estimate storage capacity and evaluate storage safety, knowledge of the trapping mechanisms that retain CO2 within geological formations, and the factors affecting these is fundamental. READ MORE

6. 4. Residual and critical saturation in geological storage of CO2 : results from field studies, pore-network modelling and laboratory experiments

   Author : Ramin Moghadasi; Auli Niemi; Philip Ringrose; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Geological CO2 storage; Residual trapping; Gas remobilization; Field experiment; Numerical modelling; Pore-network modelling; Pore-scale imaging;

   Abstract : Geological storage of CO2 in deep saline aquifers is a promising technology in the combat to reduce the atmospheric emissions of CO2. A critical component in this solution is the estimation of aquifer’s in situ capability to store CO2. READ MORE

7. 5. Modeling of geohydrological processes in geological CO2 storage – with focus on residual trapping

   Author : Kristina Rasmusson; Auli Niemi; Fritjof Fagerlund; Rainer Helmig; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; capillary trapping; CCS; characterization test; CO2; injection design; pore-network model; Hydrology; Hydrologi;

   Abstract : Geological storage of carbon dioxide (CO2) in deep saline aquifers is one approach to mitigate release from large point sources to the atmosphere. Understanding of in-situ processes providing trapping is important to the development of realistic models and the planning of future storage projects. READ MORE
