Bayesian Gaussian Inversion of Time-Lapse Seismic AVO Data
Forberg, Ole Bernhard (Master thesis, 2017)The goal of this study is to characterize an oil reservoir along a depth profile at two different points in time, based on seismic AVO data gathered at these times. We apply Bayesian methodology to the inversion problem. ... -
Bayesian inversion of seismic data using multimodal selection Gaussian prior models
Forberg, Ole Bernhard (Doctoral theses at NTNU;2021:395, Doctoral thesis, 2021) -
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 ... -
Bayesian seismic amplitude variation with offset inversion for reservoir variables with bimodal spatial histograms
Forberg, Ole Bernhard; Kjøsnes, Øyvind; Omre, Henning (Peer reviewed; Journal article, 2021)A Bayesian seismic amplitude versus offset (AVO) inversion scheme with a laterally coupled prior model for porosity, water saturation, and volume of clay is proposed. A 2-D section and a 3-D volume of an oil reservoir are ... -
Bayesian Seismic AVO Inversion Using a Laterally Coupled Multimodal Prior Model
Forberg, Ole Bernhard; Kjøsnes, Øyvind Andre Gjerde; Omre, Henning (Peer reviewed; Journal article, 2022)A Bayesian seismic amplitude versus offset (AVO) inversion scheme with a laterally coupled prior model for porosity, water saturation, and volume of clay is proposed. A 2-D section and a 3-D volume of an oil reservoir are ...
