IEAGHG Investigation of Extracted Water from CO2 Storage: Potential Benefits of Water Extraction and Lesson Learned

Abstract The Energy & Environmental Research Center analyzed formation water extraction from carbon dioxide (CO2) storage reservoirs under a project jointly sponsored by the IEA Greenhouse Gas R&D Programme and the U.S. Department of Energy. This paper presents some of the results of this project, which included a study of the impacts of formation water extraction on CO2 storage as well as the potential for the beneficial use of the extracted water. This paper also identifies several beneficial use options for the extracted water and candidate treatment technologies to achieve the water quality required by these end uses.
