Bayesian ensemble Kalman filter for Gaussian mixture models
Gryvill, Håkon; Grana, Dario; Tjelmeland, Håkon (Journal article; Peer reviewed, 2024)Inverse theory and data assimilation methods are commonly used in earth and environmental science studies to predict unknown variables, such as the physical properties of underground rocks, from a set of measured geophysical ... -
Bayesian Inversion of Time-Lapse Seismic AVO Data for Multimodal Reservoir Properties
Forberg, Ole Bernhard; Grana, Dario; Omre, Henning (Peer reviewed; Journal article, 2021)We consider time-lapse seismic amplitude versus offset (AVO) inversion for the reservoir properties porosity and water saturation, with a focus on monitoring the evolution of water saturation in a dynamic setting of ongoing ... -
