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. ... -
An evaluation of tectonostratigraphy and hydrocarbon potential of the Ellingråsa Graben, Halten Terrace, offshore Mid-Norway
Blilie, Kristin (Master thesis, 2019)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 ... -
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 (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 ... -
An integrated study for lithology and fluid prediction in the Cretaceous sediments from Halten Terrace. - Rock Physics Templates, AVO attributes and Inversion analysis.
Chiriac, Andreea (Master thesis, 2018)AVO attributes analysis and Seismic inversion are useful tools for quantitative reservoir characterization. They are used to validate hydrocarbon presence and mitigate the exploration risk. This study has as objective the ... -
Integrating rock physics laboratory data and modelling to improve uplift characterization methodology
Torset, Sondre; Holt, Rune Martin; Duffaut, Kenneth (Peer reviewed; Journal article, 2020)Modelling changes in elastic wave velocities in sediments and rocks as they undergo burial and uplift can reveal aspects of their burial history. This has implications in the petroleum risking procedures, as aspects such ... -
Is it possible to estimate the magnitude of uplift and erosion by the use of check-shot data and average velocity?
Aven, Eirik (Master thesis, 2017)This work investigates a new method in quantifying the magnitude of net erosion or net exhumation by using average velocity profiles derived from check-shot data. The fundamental principle is based on finding the same ... -
