Carbon Dioxide Saturation Estimates at Sleipner Using Seismic Imaging and Rock Physics Inversion
Dupuy, Bastien; Romdhane, Anouar; Eliasson, Peder; Yan, Hong; Torres Caceres, Veronica Alejandra; Querendez, Etor; Ghaderi, Amir (Chapter; Peer reviewed, 2017)We present an integrated approach combining Full-Waveform Inversion and rock physics inversion to estimate CO2 saturation at Sleipner. Acoustic FWI provides high-resolution P-wave velocity images where the uncertainty is ... -
Combined geophysical and rock physics workflow for quantitative CO2 monitoring
Dupuy, Bastien; Romdhane, Anouar; Eliasson, Peder; Yan, Hong (Peer reviewed; Journal article, 2021)Safe CO2 storage requires conformance verification, i.e. confirmation that the pressure and CO2 accumulation are consistent with modelling forecasts within a given uncertainty range. Quantitative estimates of relevant ... -
Inter-source seismic interferometry by multidimensional deconvolution (MDD) for borehole sources
Liu, Yi; Arntsen, Børge; Wapenaar, Kees; Romdhane, Anouar (Book, 2014)Seismic interferometry (SI) is usually implemented by crosscorrelation (CC) to retrieve the impulse response between pairs of receiver positions. An alternative approach by multidimensional deconvolution (MDD) has been ... -
Quantitative seismic characterisation of CO2 at the Sleipner storage site, North Sea
Dupuy, Bastien; Romdhane, Anouar; Eliasson, Peder; Querendez, Etor; Yan, Hong; Torres Caceres, Veronica Alejandra; Ghaderi, Amir (Journal article; Peer reviewed, 2017)Reliable quantification of carbon dioxide (CO2CO2) properties and saturation is crucial in the monitoring of CO2CO2 underground storage projects. We have focused on quantitative seismic characterization of CO2CO2 at the ... -
Rock Physics Inversion for CO2 Saturation Estimation at Sleipner - Sensitivity Tests and Baseline Application
Yan, Hong; Dupuy, Bastien; Romdhane, Anouar; Arntsen, Børge (Chapter, 2017)We demonstrate the use of rock physics inversion for estimating CO2 saturation and rock frame properties at the Sleipner CO2 storage pilot in the North Sea. We investigate the relation between rock physics properties and ...
