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. ... -
AVO Modeling and Interpretation related to Thermal Effects: Åsgard Field, Norwegian Sea
Johannessen, Tone Karin (Master thesis, 2014)In oil exploration, one of the first steps is to conduct a seismic survey to get an overview of the area of interest. If a possible reservoir is found, the only way to determine reservoir quality is to drill an exploration ... -
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, ... -
Modelling of Electromagnetic Fields in Conductive Media and development of a Full Vectorial Contrast Source Inversion Method
Wiik, Torgeir (Master thesis, 2008)Seismic surveys are well established in hydrocarbon prospecting, and technology for processing seismic data has been developed through decades. The first electromagnetic survey for hydrocarbon prospecting however, was ... -
On Processing and Inversion of Marine Magnetotelluric Data
Mütschard, Lutz (Doctoral theses at NTNU;2017:311, Doctoral thesis, 2017) -
Seismic geophysics application for Seafloor Massive Sulfides. Seafloor Massive Sulfide deposits mineral richness estimation using their acoustic impedance or zero-offset seismic.
Khayrullaev, Jokhongir (Master thesis, 2022)Seafloor massive sulfide deposits are generated in tectonically active areas such as the back-arc spreading centre, volcanic arc, and mid-ocean ridges. Seafloor massive sulfide deposits form at or near the seafloor surrounded ... -
Sensitivity of seismic well ties to attenuation effects
Czajkowski, Marcelina Karen (Master thesis, 2015)Seismic attenuation affects seismic data by reducing the amplitudes, by imposing phase distortion and by decreasing the data bandwidth. These effects need to be adequately managed to obtain satisfactory well ties. In this ... -
Strategies for Petroleum Exploration on the Basis of Bayesian Networks: A Case Study
Martinelli, Gabriele; Eidsvik, Jo; Hokstad, Ketil; Hauge, Ragnar (Journal article; Peer reviewed, 2014)The paper presents a new approach for modeling important geologicalelements, such as reservoir, trap, and source, in a unified statistical model.This joint modeling of these geological variables is useful for reliableprospect ... -
Temperature History And Its Impact On AVO Responses In The Halten Terrace Area
Hadler-Jacobsen, Helle (Master thesis, 2015)Temperature is a fundamentally important petroleum geology parameter affecting both i) reservoir quality preservation (diagenetic evolution) and ii) source rock maturation (hydrocarbon generation). The link between ...
