Ml-based porosity modeling tested on synthetic and subsurface data
Salomonsen, Einar (Master thesis, 2022)This thesis investigates if synthetic porosity models are useful as a basis for comparison between machine learning (ML) approaches to porosity prediction. In addition to the ML methods, the sequential gaussian simulation ... -
Modeling of turbidite systems in deep-water, thrust-related bivergent anticlines
Jaimes Duarte, Yvonne (Masteroppgave/UIS-TN-IER/2019;, Master thesis, 2019-06)In deep-water fold and thrust belts, thrust-related folds that switch vergence along strike can occur and are considered to have a major impact on reservoir distribution (Higgins et al., 2009). Syn-sedimentary processes ... -
Outcrop-scale fracture analysis and seismic modelling of a basin-bounding normal fault in platform carbonates, central Italy
Volatili, Tiziano; Agosta, Fabrizio; Cardozo, Nestor; Zambrano, Miller; Lecomte, Isabelle Christine; Tondi, Emanuele (Peer reviewed; Journal article, 2022)Faults are characterized by a complex internal architecture. In carbonates, the geometry, attitude, and distribution of fault-related fractures and subsidiary faults can largely affect the petrophysical properties and hy ... -
Porosity prediction from seismic data of the F3 block, offshore Netherlands, through seismic inversion and machine learning
Umar, Muhammad (Master thesis, 2022)Porosity is a key rock property that influences reservoir quality and plays an important role in petroleum exploration and production. The most common sources of information for reservoir characterization are well and ... -
Predictive Dynamic Models of the Upper Jurassic Ula Fm Aquifer Between the Ula and Oda Fields, Norwegian Central Graben, North Sea
Ghesla Rossetti, Isabella (Masteroppgave/UIS-TN-IER/2020;, Master thesis, 2020-07-15)The Ula and Oda oil fields in the southern part of the Norwegian Central Graben have high quality Upper Jurassic sandstone reservoirs from the shallow marine Ula Fm. Pressure data from the Oda field indicates communication ... -
Quantitative seismic interpretation using converted PS waves: A case study from the Oseberg South Field, North Sea
Frette, Lars Ulsund (Masteroppgave/UIS-TN-IER/2018;, Master thesis, 2018-06)The converted wave (PS) seismic in combination with the compressional wave (PP) seismic may help in better description and understanding of subsurface stratigraphic and structural features. Since compressional and shear ... -
Reservoir Modeling and Uncertainty Estimation: A Comparison Between Stochastic and Deterministic Inversion.
Rotar, Vlad (Masteroppgave/UIS-TN-IER/2019;, Master thesis, 2019-06-29)This study compares the uncertainty estimation based on both deterministic and stochastic inversion with the Gauss Simulation technique applied to modelling the distribution of limestone facies in a sand-shale reservoir. ... -
Salt tectonics on the Cod Terrace and Sørvestlandet High, Central North Sea
Aarseth, Ville August (Masteroppgave/UIS-TN-IER/2019;, Master thesis, 2019-06-15)Four high- to moderate-quality 3D seismic surveys and public well data were used to define the structural framework and understand the Mesozoic and Cenozoic structural evolution of the salt diapirs on the Cod Terrace and ... -
Sediment growth around salt diapirs: Analysis and interpretation using full-azimuth seismic data from the Central Nordkapp Basin, SW Barents Sea
Tatayo, Alexandra (Masteroppgave/UIS-TN-IER/2019;, Master thesis, 2019-06-15)The Nordkapp Basin (Norwegian Barents Sea) comprises a large number of salt structures developed during Late Paleozoic-Early Mesozoic. Salt diapirism is dominant in this basin, and it influences all aspects of the petroleum ... -
The Seismic Imaging and Interpretation of Faults: A Case Study from the Snøhvit Field, Barents Sea
Cunningham, Jennifer Elizabeth (PhD thesis UiS;568, Doctoral thesis, 2021-01)An accurate understanding of faults in the subsurface is critical to successful petroleum exploration and production. Faults define sediment distribution pathways during deposition, act as barriers or conduits to fluid ... -
Seismic imaging of salt-influenced compressional folds
Castillo Valencia, Diana Carolina (Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06)Fold-and-thrust belts (FTB) detaching on salt have a high potential for developing trap structures and host large oil and gas fields. Due to their high structural complexity and often low-quality seismic data, their ... -
Structural evolution of basement fault bounded fold structures using forward modelling methods: Application to the Beta structure in the Smeaheia area.
Gilje, Hanne (Master thesis, 2022)In rift systems, extensional fault-related folds play an important part on the deformation pattern, and they are key to understand fault and sediment growth. In this thesis, the Beta structure in the Smeaheia area, Horda ... -

Muñoz, J.A.; Hardy, S.; Vidal-Royo, O.; Koyi, H.; Cardozo, Nestor (Journal article; Peer reviewed, 2013-03)This paper reports on the integration of different modelling techniques to construct a unified conceptual model of structural evolution of the Pico del Águila anticline (External Sierras, southern Pyrenees, Spain). The ... -
Structural geologic modeling and restoration using ensemble Kalman inversion
Oakley, David Owen Smith; Cardozo, Nestor; Almendral Vazquez, Ariel; Røe, Per (Peer reviewed; Journal article, 2023-06)We demonstrate the use of Ensemble Kalman Inversion (EKI) for building three-dimensional, multi-fault, kinematically restorable structural geologic models, by means of a workflow in which fault geometry, the distribution ... -
Tectonic evolution of the Marulk Basin and adjacent highs, northern North Sea
