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 ... -
Modeling burial induced changes in physical sandstone properties - A case-study of North Sea and Norwegian Sea sandstone formations
Blazevic Vucelic, Lara Antonia (Master thesis, 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. ... -
Modelling Geophysical Properties of Crustal Igneous Rocks
Haaland, Malin Lerstøl (Master thesis, 2017)The chemical composition of crustal igneous rocks strongly affects their geophysical properties. In order to model these effects, a classification scheme based on silica content was applied, resulting in the classes felsic, ... -
Net exhumation estimation from seismic traveltimes and burial history modelling in the Western Barents Sea.
Martinez Guzman, Ricardo Jose (Master thesis, 2018)A new seismically based technique is proposed for the estimation of net exhumation magnitudes in sedimentary basin areas. The method uses traveltimes mapped from well log data or pre-stack seismic data, starting from the ... -
Net Exhumation Estimation Using an Effective-medium Technique Based On Seismic Traveltime Measurements
Martinez, Ricardo Jose; Duffaut, Kenneth (Chapter, 2018)We propose a new seismically based technique for estimating net exhumation magnitudes on sedimentary basin areas. The method uses traveltime measurements mapped from e.g. seismic data, or ray traced well log data, starting ... -
Overpressure Distribution of the Central and Northern Viking Graben - A study of Cretaceous, Jurassic and Triassic sediments
Tjønnfjord, Karl Hampus Viberg (Master thesis, 2017)The North Sea was subjected to massive faulting during the Jurassic period, resulting in a complex graben structure. Consequently, the Viking Graben is heavily compartmentalized and overpressures occur within the Jurassic ... -
Permeability Prediction from Acoustic Velocity
Vølstad, Hanna Skårdal (Master thesis, 2016)Permeability is estimated in the middle Jurassic Garn Fm. in the Haltenbanken area in the Norwegian Sea by combining the Kozeny-Carman model for permeability estimation with Raymer s model for porosity estimation. The ... -
Porøsitetstrender estimert fra sonic og seismiske p-bølge hastighetsdata.
Flatøy, Vegard (Master thesis, 2016)Vi utvikler med dette arbeidet en ny model og metodikk for å estimere lavfrekvente porøsitetstrender fra p-bølge hastighetsdata med en mulighet for å forbedre estimert porøsitet ved å inkludere en litologisk parameter for ... -
Predicting horizontal resistivity trends: An example from the Barents Sea
Wang, Ying; Duffaut, Kenneth; Nordskag, Janniche Iren (Chapter, 2018)Exploring the major controlling factors on resistivity depth trends in sedimentary basins is an interesting subject from both scientific and commercial perspectives. We propose a rock-physics based workflow for predicting ... -
Predicting Porosity and Clay Trends from P-Wave Velocity
Helle, Anne Cathrine (Master thesis, 2018)P-waves are sensitive for several parameters, and when P-waves are the only information present, the primary effects have to be identified. In this study, two models are created to describe the relation between porosity, ... -
Quick clay monitoring using distributed acoustic sensing: A case study from Rissa, Norway
Rørstadbotnen, Robin Andre; Dong, Hefeng; Landrø, Martin; Duffaut, Kenneth; Growe, Kevin; Kakhkhorov, Umedzhon; Wienecke, Susann; Jacobsen, Joacim (Peer reviewed; Journal article, 2023)Quick clay avalanche is one of the most devastating landslide types worldwide. Hence, an early warning system is in demand to mitigate the fatal consequences caused by such events. To address this, distributed acoustic ... -
