Prospective CO2 saline resource estimation methodology: Refinement of existing US-DOE-NETL methods based on data availability

Abstract

Carbon storage resource estimation in subsurface saline formations plays an important role in establishing the scale of carbon capture and storage activities for governmental policy and commercial project decision-making. Prospective CO 2 resource estimation of large regions or sub-regions, such as a basin, occurs at the initial screening stages of a project using only limited publicly available geophysical data, i.e. prior to project-specific site selection data generation. As the scale of investigation is narrowed and selected areas and formations are identified, prospective CO 2 resource estimation can be refined and uncertainty narrowed when site-specific geophysical data are available. Here, we refine the United States Department of Energy-National Energy Technology Laboratory (US-DOE-NETL) methodology as the scale of investigation is narrowed from very large regional assessments down to selected areas and formations that may be developed for commercial storage. In addition, we present a new notation that explicitly identifies differences between data availability and data sources used for geologic parameters and efficiency factors as the scale of investigation is narrowed. This CO 2 resource estimation method is available for screening formations in a tool called CO 2-SCREEN.

A Hierarchical Framework for CO2 Storage Capacity in Deep Saline Aquifer Formations

“…Most-capacity evaluation methodologies currently use volumetric-based or mass-balanced approaches for estimating theoretical CO 2 capacity in a geological medium at regional and sub-basin scales (Goodman et al, 2011;Goodman et al, 2016). The US-DOE, Carbon Sequestration Leadership Forum (CSLF), International Energy Agency, Greenhouse Gas R&D Programmer, and the United State Geological Survey (USGS) have independently developed methodologies for capacity assessment of CO 2 storage in open aquifers (Bachu et al, 2007;Bradshaw et al, 2007;Co2Crc, 2008;Zhou et al, 2008;Iea-Ghg, 2009;Kopp et al, 2009a;Kopp et al, 2009b;Goodman et al, 2011;Goodman et al, 2013;Doe-Netl, 2018).…”

Simulating and Quantifying Multiple Natural Subsea CO2 Seeps at Panarea Island (Aeolian Islands, Italy) as a Proxy for Potential Leakage from Subseabed Carbon Storage Sites

“…Carbon dioxide (CO 2 ) capture and storage (CCS) has been discussed as a potentially key tool in the stringent mitigation required to restrict climate warming to within 2 °C relative to preindustrial levels. , CCS represents the capture of CO 2 mainly from large point sources and its injection into subsurface reservoirs, usually at 800–2000 m below the seafloor. ,− In Europe, CO 2 storage capacity is chiefly located offshore within sandstone aquifers. , Currently, this storage capacity lies principally within Norwegian waters, where the multinational energy company Equinor (formerly Statoil ASA) operates the Sleipner CCS facility that has injected ∼1 Mt y –1 of CO 2 into the Utsira formation since 1996. , Procedures guide the selection of appropriate subseabed CO 2 storage sites, ,− which have been suggested to present lower risks for human populations in case of accidental leakage compared to terrestrial locations. , However, there is a need to identify suitable procedures for the monitoring of active and closed marine storage sites to ensure their adequate operation and enable identification and quantification of potential leaks …”
