Combined geophysical and rock physics workflow for quantitative CO2 monitoring
(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 ... -
Gas flow through shallow sediments - A case study using passive and active seismic field data
(Journal article; Peer reviewed, 2019)Offshore Quaternary sediment sequences are generally weak and unconsolidated, and fluid flow through these rock formations is hard to predict or model. Surface flow observations, such as gas seeps, often appear random and ... -
Numerical analysis of mixed-mode rupture propagation of faults in reservoir-caprock system in CO2 storage
(Journal article, 2018)Injection-induced seismicity and caprock integrity are among the most important concerns in CO2 storage operations. Understanding and minimizing fault/fracture reactivation in the first place, and rupture growth/propagation ... -
Qualitative and quantitative experimental study of convective mixing process during storage of CO2 in heterogeneous saline aquifers
(Journal article; Peer reviewed, 2018)CO2 dissolution is considered as one of the most promising mechanisms for trapping of free-phase CO2 into brine. It causes an increased density of the brine and initiation of gravitational instability that eventually leads ... -
Time lapse seismic analysis of the Tohoku-Oki 2011 earthquake
(Journal article, 2019)A detailed time lapse seismic analysis of subsurface movements is presented using seismic 2D lines acquired prior to and after the Tohoku-Oki earthquake offshore Japan in 2011. Estimated movements of the seabed from the ...
