“…During last years, studies focussing on CO 2 sequestration have known growing interest as part of climate mitigation researches (Holloway et al, 2007;Wildenborg et al, 2009;Winthaegen et al, 2005). By them, studies dedicated to a better knowledge of natural analogues are of primary interest, as they focus either on sites where CO 2 is naturally stored at depth from many years (e.g.…”

Natural analogues studies have received growing interest during preceding years in a CCS perspective. There is a strong willing to deploy robust and reliable technologies to ensure the safety and integrity of CO 2 underground storages. Here we present a dataset acquired in the Eifel volcanic district, using geochemical monitoring methods focusing on both dissolved and gaseous species.Onshore and offshore monitoring (Lake Laacher See) were performed to depict spatial behaviour of CO 2 natural releases. Additional gaseous species, mainly helium and radon, were also monitored to better assess the shapes of gas vents, using methodologies that were learned from hydrological and tectonic applications. Lake water monitoring allowed the characterisation of the water body itself, in terms of lateral heterogeneities, to evaluate the impact of CO 2 deep degassing near the bottom of the lake. The use of a dedicated sensor for monitoring in situ CO 2 partial pressure did not provide more valuable information that was learned from more classical physico-chemical parameters. From those investigations, the usefulness of geochemical monitoring is still demonstrated, but the use of complementary approaches and methods is still needed to get a powerful set of techniques able to warn in case of leakages occurring from depth.

“…These rocks are pervasively fractured owing to the tectonic forces active during their emplacement. However, the behaviour of CO 2 in such media, and the physical and chemical changes that can be expected in rocks if CO 2 is injected, are still a concern in the scientific community (Holloway et al, 2007;Huijgen et al, 2006). The sequestration capacity of deep oceans is about 104 GtC (e.g., Freund & Ormerod, 1997;Lackner, 2003).…”

“…Numerous CO 2 sequestration approaches, including ocean, terrestrial, geological, biological and chemical options are currently being studied (Conrad & Klose, 1999;Freund & Ormerod, 1997;Friedmann, 2007;Gunter et al, 1997;Holloway, 1997;Lackner et al, 1995;Lackner et al, 1998;Lackner, 2003;Metz et al, 2005;O'Connor et al, 2002;Parson & Keith, 1998;Xu et al, 2004). As a substantial share of CO 2 emissions must be stored, the retention or sequestration of CO 2 in geological reservoirs is currently the applied option (e.g., Weyburn, Canada; Sleipner, North Sea; Holloway et al, 2007). Deep aquifers and depleted reservoirs in oil and gas fields have stored natural gas and crude oil for million of years.…”

“…This means the variances of atmospheric CO 2 concentrations at the study area were higher than the CO 2 concentrations in its northern area across all time scales. The CO 2 -EOR project, just like other geological carbon storage, was considered to operate under zero or very limited predictable leakage (Holloway, Pearce, Hards, Ohsumi, & Gale, 2007). Currently there is no standardized value for tolerable seepage.…”

Enhanced oil recovery with carbon dioxide (CO 2 -EOR) is considered to be a cost effective way for carbon capture and storage. However, due to the complexity of geological structure in underground reservoirs, long-term leakage is possible. A case study of CO 2 -EOR has been conducted at Citronelle, Alabama in the United State of America. A total of 8,036-ton of CO 2 were injected from November 2009 to September 2010 and some leakages via production were identified by isotopic analysis in May 2010. In this study, remote sensing data of CO 2 and methane (CH 4 ) concentrations, and aerosol optical depth (AOD) at a large scale were used to monitor emissions to atmosphere at the study site. Based on the observed monthly CO 2 and CH 4 concentrations in the atmosphere at the study site and surrounding areas, some abnormal values related to possible emission were identified at different time scales by correlation, variance and entropy analysis. The annual average of ratios between CO 2 concentration and CH 4 concentration, which might be due to CO 2 emission, reached the highest value in 2009. In comparison with surrounding areas, the monthly values of AOD at the study site were relatively higher, especially during the time periods of 2008, 2009 and part of 2010. Our results might confirm the isotopic analysis at the ground and may provide more detailed information. Therefore, through this approach remote sensing data could be used to monitor and evaluate emissions from areas involved in CO 2 -EOR at a large scale and provide helpful information for ecological assessment of CO 2 -EOR.
