Factors Governing Pressure Behavior Under CO2 Injection in a Faulted Basin-Scale Model
Nybråten, Eline (Master thesis, 2022)Fullskala CO2-fangst og lagringsprosjekter vil kunne bidra som et effektivt klimatiltak ved å redusere konsentrasjonen av drivhusgasser i atmosfæren. Geologiske formasjoner med egnede lagringsbetingelser har enorme ... -
Gas flow through shallow sediments - A case study using passive and active seismic field data
Landrø, Martin; Wehner, Daniel; Vedvik, Noralf; Ringrose, Philip; Løhre, Nora Løw; Berteussen, Karl-Andreas (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 ... -
