Leakage risk assessment was conducted for a potential CO2 storage site modeled in Pickaway County, Ohio. Using the National Risk Assessment Partnership’s (NRAP) Integrated Assessment Model NRAP-Open-IAM, we assessed the risk of brine and CO2 leakage along nearby, hypothetical cemented wellbores and through the caprock layer above the storage reservoir. The following components of NRAP-Open-IAM were used to setup the model: stratigraphy, reservoir CO2 saturation and pressure lookup tables, cemented wellbore, aquifer, and seal horizon. The static earth model and dynamic reservoir model of the storage site provided the foundation for the inputs used in the model, such as distributions of geologic properties such as permeability, and time-varying pressure, and CO2 saturation responses to CO2 injection. The outputs of the cemented wellbore model are the leakage rates along cemented wellbores into a thief zone and shallow aquifer that are considered in the area. The seal horizon component calculates flux from the storage reservoir into and through the overlying caprock. With increased commercial interest in CCUS development, NRAP-Open-IAM represents a viable option for assessing geologic risks associated with permanent carbon storage.Keywords: risk assessment, leakage, cemented wellbore, seal horizonPermalink: https://doi.org/10.1190/image2022-3749378.1FiguresReferencesRelatedDetails Second International Meeting for Applied Geoscience & EnergyISSN (print):1052-3812 ISSN (online):1949-4645Copyright: 2022 Pages: 3694 publication data© 2022 Published in electronic format with permission by the Society of Exploration Geophysicists and the American Association of Petroleum GeologistsPublisher:Society of Exploration Geophysicists HistoryPublished Online: 15 Aug 2022 CITATION INFORMATION Stuart Skopec, Sanjay Mawalkar, Veronika Vasylkivska, Priya Ravi Ganesh, Autumn Haagsma, and Mark Kelley, (2022), "Risk assessment of carbon storage at potential Midwest Regional Carbon Initiative (MRCI) sites using NRAP Open-IAM component models," SEG Technical Program Expanded Abstracts : 515-518. https://doi.org/10.1190/image2022-3749378.1 Plain-Language Summary Keywordsrisk assessmentleakagecemented wellboreseal horizonPDF DownloadLoading ...
