    • 3D Analysis of Temperature and Heat flow in Steady State Approximation in the Halten Terrace 

      Hovda, Trine (Master thesis, 2015)
      Thermal effects and heat flow distribution are of major interest as they affect the petroleum system in a sedimentary basin. Heat controls the maturation and generation of hydrocarbons as well as the reservoir quality. ...

      Ellingråsa Graben er en grabenstruktur lokalisert i den umiddelbare hengblokken til Bremstein Forkastningskompleks (BFC), i Norskehavet, 65°N. De første letebrønnene i Norskehavet ble boret og funnet tørre på denne strukturen, ...
    • An integrative modelling of the Vøring Basin to understand the observed temperature anomalies 

      Chernyshova, Alena (Master thesis, 2019)
      Letebrønner i Vøringbassenget avslører svært varierende termisk profil. Høye temperatur- og varmestrømavvik er oppdaget på Gjallarryggen, Grønøyhøyden og i Vestfjordenbassenget, mens observerte temperaturer på Utgardhøyden ...
    • Automated Log Data Analytics Workflow – The Value of Data Access and Management to Reduced Turnaround Time for Log Analysis 

      Torres Caceres, Veronica Alejandra; Duffaut, Kenneth; Westad, Frank Ove; Stovas, Alexey; Johansen, Yngve Bolstad; Jenssen, Arne Johannes Kaaijk (Peer reviewed; Journal article, 2022)
      The oil and gas industry of today is undergoing rapid digitalization. This implies a massive effort to transform standard work procedures and workflows into more efficient practices and implementations using machine learning ...
    • Automated Well-Log Depth Matching – 1D Convolutional Neural Networks Vs. Classic Cross Correlation 

      Torres Caceres, Veronica Alejandra; Duffaut, Kenneth; Yazidi, Anis; Westad, Frank Ove; Johansen, Yngve Bolstad (Peer reviewed; Journal article, 2022)
      During drilling and logging, depth alignment of well logs acquired in the same borehole section at different times is a vital preprocessing step before any petrophysical analysis. Depth alignment requires high precision ...
    • Burial induced changes in physical sandstone properties: A case-study of North Sea and Norwegian Sea sandstone formations 

      Blazevic V., Lara A.; Duffaut, Kenneth; Avseth, Per Åge (Journal article; Peer reviewed, 2017)
      The changes in physical properties of sandstones with burial depth are a result of mechanical and chemical compaction processes. These processes are affected by rock microstructure, pressure regimes and temperature history. ...
    • Contribution of Rock Physics Laboratory Tests and Modelling to Improving Uplift Estimates 

      Torset, Sondre; Duffaut, Kenneth; Holt, Rune Martin (Journal article; Peer reviewed, 2018)
      Most currently applied procedures for uplift estimation rely on assumptions that porosity and seismic / log measured velocity are unaltered by the uplift process. Laboratory experiments have been performed with synthetic ...
    • Contribution of Rock Physics Laboratory Tests and Modelling to Improving Uplift Estimates 

      Torset, Sondre; Duffaut, Kenneth; Holt, Rune Martin (Chapter, 2018)
      Most currently applied procedures for uplift estimation rely on assumptions that porosity and seismic / log measured velocity are unaltered by the uplift process. Laboratory experiments have been performed with synthetic ...
    • Enhanced lithological description of the Jurassic sequence in the Viking Graben and Oseberg Terrace using machine learning 

      Bøe, Harald Wie (Master thesis, 2018)
      Automatic classifications of well logs using machine learning techniques has gained improved attention within the last couple of years among others for increasing the accuracy and speed of lithofacies prediction on wireline ...
    • Estimating Horizontal Resistivity Trends in Sedimentary Rocks: A Case Example from the Northern North Sea 

      Duffaut, Kenneth; Wang, Ying; Nordskag, Janniche Iren (Journal article; Peer reviewed, 2018)
      Understanding the major controlling factors on the horizontal resistivity-depth trends of sedimentary rocks in any given basin around the world are interesting from both scientific and commercial perspectives. Hence, we ...
    • Estimating Net Erosion in the Western Barents Sea 

      Elks, Richard Anthony (Master thesis, 2016)
      Quantification of uplift and erosion in the western Barents Sea has been a relevant and challenging problem for geoscientists for several decades. Uplift and erosion processes have implications for petroleum prospectivity, ...
    • Estimation of Anisotropy Parameters and AVO modeling of the Troll Field, North Sea 

      Haktorson, Hilde (Master thesis, 2012)
      In the work of this Master's thesis, the anisotropy parameters, epsilon and delta, for the reservoir and the cap rock on the Troll Field have been estimated. This was done using well logs from 35 wells, including the P-wave ...
    • Estimation of Barents Sea uplift by comparison of linear trend lines from well log properties 

      Erichsen, Stian Werner (Master thesis, 2017)
      Linear trends of measured well log properties have been compared in this thesis, to see if uplift in the Barents Sea can be estimated. Reference trends from areas that have not been uplifted, wells 15/9-6, 34/7-1, 34/7-5 ...
    • Estimation of Timeshifts and Velocity Changes from 4D Seismic Analysis: A Case Study from the Norne Field 

      Erichsen, Lene Lykke (Master thesis, 2018)
      The scope of this thesis is to investigate whether it is possible to determine the vertical strain in the overburden directly from the 4D seismic data from the Norne field in the Norwegian sea, by using changes in traveltime ...
    • Evaluation of N/G distribution of the Tofte Formation in the Smørbukk Field through AVO attribute inversion with a focus on anisotropy and tuning effects 

      Johannessen, Oda Marie (Master thesis, 2019)
      Tofte-formasjonen i Smørbukk-feltet er svært kompleks med store laterale variasjoner i N/G-fordeling. På grunn av formasjonens dyp har seismiske datasett lav oppløsning, og amplituderesponsen til formasjonen lider derfor ...
    • Generative Adversarial Networks for Seismic Interpretation 

      Huso, Erik Arne (Master thesis, 2020)
      Arbeidsprosesser der tolkning av seismikk inngår, er en nødvendig del av prosjekter der olje- og gassforekomster oppdages. Selv om nylige fremskritt i forskningen rundt dyp læring har gjort det mulig å forenkle noe av ...
