The Seismic Analyzer: Interpreting and Illustrating 2D Seismic Data
(Peer reviewed; Journal article, 2008)We present a toolbox for quickly interpreting and illustrating 2D slices of seismic volumetric reflection data. Searching for oil and gas involves creating a structural overview of seismic reflection data to identify ... -
Seismic Attributes for Carbonates
(Master thesis, 2009-06-02)Seismic attributes can reveal important information about rock properties, and rock physics modeling provide a link between geological and seismic parameters. Carbonate rocks can have wide variations in properties due to ... -
Seismic characterization of reservoirs with multiple fracture sets using velocity and attenuation anisotropy data
(Journal article, 2011)Knowledge about the spatial distribution of the fracture density and the azimuthal fracture orientation can greatly help in optimizing production from fractured reservoirs. Frequency-dependent seismic velocity and attenuation ... -
Seismic data analysis of an onshore-offshore transition zone at Ramså Basin, Norway – a modelling study
(Master thesis, 2022-10-03) -
Seismic depth imaging of complex structures An example from Zagros fold and thrust belt, Iran
(Doctoral thesis, 2006-05-24) -
Seismic Event Classification using Machine Learning
(Master thesis, 2021-06-02)The manual detection of seismic events is a labor intensive task, requiring highly skilled workers continuously analyzing recorded waveforms. Previous work has shown the potential of machine learning methods for aiding in ... -
Seismic expression of shear zones: Insights from 2-D point-spread-function based convolution modelling
(Journal article; Peer reviewed, 2020)Shear zones are common strain localization structures in the middle and lower crust and play a major role during orogeny, transcurrent movements and rifting alike. Our understanding of crustal deformation depends on our ... -
A seismic field test with a Low level Acoustic Combustion Source and Pseudo Noise codes
(Journal article, 2007-01-20)The Low level Acoustic Combustion Source (LACS) is a new type of pulsed underwater acoustic source with an output level of 0.5-1.0 barm peak to peak. The source is based on a combustion engine and intended for shallow ... -
Seismic hazard in Norway due to large earthquakes
(Master thesis, 2015-06-01)There are many faults located in Norway, posing as potential earthquake sources. Even though the seismicity is characterized as low to moderate, earthquakes of magnitude 3.5 or lower occur regularly. The seismic hazard ... -
Seismic hazard of the Izmir region, Turkey, based on a probabilistic seismic hazard assessment and stochastic ground motion simulations
(Master thesis, 2015-06-01)The purpose of this thesis is to conduct a seismic hazard analysis of the region surrounding Izmir. The chosen area is located in a very active seismic region with a high seismicity due to large amount of earthquakes. In ... -
Seismic imaging of faults and fault zones: insight through modelling for improved interpretation
(Master thesis, 2022-06-01)Faults and fault zones in the subsurface can create problems in reservoir production and well placement if gone un-detected because of restriction of fluid flow or affecting the ability of the reservoir to hold fluids. In ... -
Seismic Interpretation and Basin Modeling of the Svalbard Margin and Knipovich Ridge
(Master thesis, 2014-12-11)The Knipovich Ridge is a 550km long system situated on the seafloor west of Svalbard in the Northern Atlantic Ocean. It is a relatively young divergent boundary and ridge in the Northern Mid-Atlantic Ridge system. It is ... -
Seismic Modeling for Geothermal Reservoir Characterization
(Master thesis, 2016-05-31)The world's energy demand is increasing and there is a need for alternative energy sources to replace depleting fossil fuels. Geothermal energy could be an important part of these new sources of energy. For efficient and ... -
Seismic modeling of plaster models deformed in extension and contraction
(Master thesis, 2014-11-18)The effects of overburden, burial depth, source-receiver distance and frequency on seismic resolution have been studied in this thesis. Synthetic seismic sections of two plaster models, where a volume of plaster has been ... -
Seismic modelling and deconvolution of prestack depth migrated images through ray-based Point-Spread Functions
(Doctoral thesis, 2021-12-15)Seismic modelling involves simulating the propagation of waves through an Earth model to retrieve information about the subsurface. If an a priori Earth model is known, seismic modelling allows geoscientists to assess how ... -
Seismic modelling of the stratigraphic architecture of syn-rift deep-water channel complexes in the Corinth Rift, Greece
(Master thesis, 2022-08-03)Deep-water systems in rift basins lack extensive research because they tend to be buried in the subsurface making them hard to study directly. Rare, exhumed deep-water syn-rift depositional systems can therefore provide ... -
Seismic monitoring of CO2 sequestration – effects of saturation, pressure and temperature.
(Master thesis, 2021-06-22)Time-lapse seismic monitoring of carbon sequestration at Sleipner has revealed the seismic signature of injecting CO2 into the shallow Utsira reservoir. Several bright spot anomalies have occurred within the reservoir unit ... -
Seismic on floating ice: data acquisition versus flexural wave noise
(Journal article; Peer reviewed, 2019)Geophysical surveying of the Arctic will become increasingly important in future prospecting and monitoring of the terrestrial and adjacent areas in this hemisphere. Seismic data acquired on floating ice are hampered with ...
