    • A Simulation Analysis of CO2 Capture and Underground Storage Monitoring in Smeaheia 

      Anyosa, Susan; Bunting, Scott William Christopher; Eidsvik, Jo; Romdhane, Mohamed Anouar (Chapter, 2019)
      The emissions of CO2 are an environmental problem and one possible solution is its capture and conduct underground storage (CSS). However, there is potential risk of leakage, and to aid in this challenge we propose to use ...

    • Artificial Intelligence for Well Integrity Monitoring Based on EM Data 

      Hosseini, Seyed Ehsan; Zonetti, Simone; Romdhane, Mohamed Anouar; Dupuy, Bastien; Arntsen, Børge (Chapter, 2021)
      Monitoring of integrity of plugged and abandoned (P&A'ed) wells is of interest for the oil and gas industry and for CO2 storage. The purpose of this study is to develop artificial intelligence (AI)-based approaches to ...

    • Assessing the value of seismic monitoring of CO2 storage using simulations and statistical analysis 

      Anyosa, Susan; Bunting, Scott William Christopher; Eidsvik, Jo; Romdhane, Mohamed Anouar; Bergmo, Per Eirik Strand (Peer reviewed; Journal article, 2021)
      Successful storage of CO2 in underground aquifers requires robust monitoring schemes for detecting potential leakage. To aid in this challenge we propose to use statistical approaches to gauge the value of seismic monitoring ...

    • CO2 saturation estimates at Sleipner (North Sea) from seismic tomography and rock physics inversion 

      Yan, Hong; Dupuy, Bastien; Romdhane, Mohamed Anouar; Arntsen, Børge (Journal article; Peer reviewed, 2018)
      CO2 saturations are estimated at Sleipner using a two‐step imaging workflow. The workflow combines seismic tomography (full‐waveform inversion) and rock physics inversion and is applied to a two‐dimensional seismic line ...

    • Offset dependence of overburden time-shifts from ultrasonic data 

      Bakk, Audun; Holt, Rune Martin; Bauer, Andreas; Dupuy, Bastien; Romdhane, Mohamed Anouar (Journal article; Peer reviewed, 2020)
      Depletion or injection into a reservoir implies stress changes and strains in the reservoir and its surroundings. This may lead to measurable time-shifts for seismic waves propagating in the subsurface. To better understand ...

    • Offset-Dependent Overburden Time-Shifts from Ultrasonic Data 

      Bakk, Audun; Holt, Rune Martin; Bauer, Andreas; Dupuy, Bastien; Romdhane, Mohamed Anouar (Chapter, 2019)
      Depletion or injection into a reservoir implies stress and strain changes in the reservoir and its surroundings. This may lead to measurable time-shifts for seismic waves propagating in the subsurface. We have measured ...

    • Rock physics inversion for CO2 characterization at Sleipner 

      Yan, Hong (Master thesis, 2017)
      We combine Full-Waveform Inversion (FWI) and rock physics inversion to provide quantitative estimates of CO2 saturation at Sleipner. The rock physics tool is based on uniform saturation and patchy saturation rock physics ...
