Remote sensing of CO2 leakage from geologic sequestration projects

Harnessing the power of machine learning for carbon capture, utilisation, and storage (CCUS) – a state-of-the-art review

“…By combining the information from the AE sensors and relevant temperature and pressure data, a leakage location and estimation model based on ML algorithms should be developed for the safe operation of the CCUS pipe networks. Moreover, for the large-area monitoring of a CO 2 storage site, remote sensing techniques, such as hyperspectral imaging, aerial imaging and satellite imaging, should be considered [180][181][182] . Meanwhile, in-field pressure and seismic transducers may also be applied for the local-area monitoring of a CO 2 storage site 183 .…”

Sizing a geodetic network for risk-oriented monitoring of surface deformations induced by CO 2 injection: Experience feedback with InSAR data collected at In-Salah, Algeria

“…Rinaldi and Rutqvist, 2013) in the vicinity of the injection well. A leakage at depth could also be detected through surface deformations (Jung et al, 2013;Verkerke et al, 2014). According to McColpin (2009), surface-deformation measurements can be used to monitor fracture, caprock integrity and out-of-zone fluid movement.…”

Early atmospheric detection of carbon dioxide from carbon capture and storage sites

“…Leaked CO 2 can contaminate shallow aquifers and surface water bodies and eventually reach the atmosphere with potential adverse impacts on ecosystem and human health (Keating et al, 2013 ). To gain and preserve public support for CCS, it will be necessary to implement technologies for the early detection and rapid mitigation of CO 2 from storage sites (Bruant et al, 2002 ; Verkerke et al, 2014 ).…”

“…CCS leaks can be detected at local sites by monitoring soil or atmospheric CO 2 concentrations (Cohen et al, 2013 ; Schutz et al, 2013 ; Verkerke et al, 2014 ), whereas leak detection can involve the use of chemical tracers (Myers et al, 2013 ). At all scales, including global, ratios of gases or their isotopes have been proposed as strategies for identifying CO 2 leaks from CCS sites (Keeling et al, 2011 ; Romanak et al, 2013 ; Ma et al, 2013 ).…”
