(Master thesis, 2020)Dannelse-, smelte- og nedfallsprosessene til en iskjøving langs fylkesvei 715 i Trøndelag i Norge ble kartlagt gjennom vinteren 2019/2020, med det formål å undersøke påvirkningen av luft- og bergtemperatur på endringer i ... -
Iceberg ploughmarks illuminated by shallow gas in the central North Sea
(Journal article; Peer reviewed, 2014)Conventional 3D seismic data provides direct evidence for glacial influence during the early Pleistocenesedimentation in the Central North Sea. We identify iceberg ploughmarks as dim linear to curve-linearfeatures in three ... -
Identification and Effects of Thin Vertical Intrusions on Seismic Data
(Master thesis, 2013)In this report I consider a case with a simple three-dimensional two-layer model penetrated by a thin vertical intrusion. Synthetic seismic data is generated, and a number of events are identified. The identified events ... -
Identification of Nanocellulose Retention Characteristics in Porous Media
(Journal article; Peer reviewed, 2018)The application of nanotechnology to the petroleum industry has sparked recent interest in increasing oil recovery, while reducing environmental impact. Nanocellulose is an emerging nanoparticle that is derived from trees ... -
Identification of the Transition Between Two Phase Flow Regimes in Sphere Packs
(Master thesis, 2018)This thesis presents an experimental investigation of the simultaneous immiscible two phase flow, in three dimensional porous media made up of glass beads. The objective of this thesis was to find the scaling relation ... -
Identifisering og Kvantifisering av utvalgte Designparametre for underjordsbrytning i Vestmalmen, Rana Gruber AS
(Master thesis, 2020)I denne oppgaven presenteres det kvantifiserte designparametre for underjordsdrift på Vestmalmen ved Rana Gruber i Ørtfjell. Målet er å komme med en anbefaling på dimensjoner og om mulig komme frem til den mest passende ... -
Igneous Evolution and Ore-Forming Potential of the Ulleren Mafic-Ultramafic Complex
(Master thesis, 2024)Ulleren er en mafisk intrusjon som ligger i Kongsberg Terrenget i den Svekonorvegiske fjellkjeden. Ved hjelp av feltarbeid, petrografiske studier samt analyser av hoved- og sporelementer, var hovedmålet med denne oppgaven ... -
Igneous Hydrothermal Alteration and Ore-Forming Processes in the Land's End Granite, Nanjizal
(Master thesis, 2015)This study addresses the hydrothermal alteration and mineralization related to a system of tourmaline-quartz veins intersecting biotite-granite in Nanjizal, in the Land s End granites of the cornubian batholith. Nanjizal ... -
Iintegrated study of the Veslebjørnprospect, South Norwegian North Sea
(Master thesis, 2010)In the study of a sedimentary basin, a good geological background of the area is fundamental, and then, seismic data and well logs are essential tools for its characterization. The main objective of this project is to ... -
Image-based and risk-informed detection of Subsea Pipeline damage
(Peer reviewed; Journal article, 2023)As one of the most important assets in the transportation of oil and gas products, subsea pipelines are susceptible to various environmental hazards, such as mechanical damage and corrosion, that can compromise their ... -
Imaging of Tertiary Turbidite Channel offshore Angola, West Africa
(Master thesis, 2010)The Tertiary of Angola reveals complex submarine channel that mainly are controlled by salt tectonics. These deep water channels are sinuous, and using 3D seismic from block 34, offshore West Africa, it was possible to ... -
Imaging Reservoir Geology of the Troll West Field in the North Sea by 3D Seismic Interpretation
(Master thesis, 2014)The Troll Field is called super giant gas field . This is the second largest gas field of offshore Europe with its 1670 billion m3 of gas and 615 million m3 of oil initially in place. The Troll Field was discovered in ... -
Impact of frequency-dependent anisotropy on azimuthal P-wave reflections
(Peer reviewed; Journal article, 2018)Seismic anisotropy has widely been used for the characterization of fractures in a reservoir. Recent work has demonstrated the effect of seismic dispersion on producing a frequency-dependent reflection coefficient, which ... -
Impact of Permeability Variations and Well Placement on CO₂ Storage Efficiency in Saline Aquifers Utilizing 3D Visualization Techniques
(Master thesis, 2024)Forskningsspørsmålet i denne studien fokuserte på hvordan CO2 kan lagres mer effektivt under jorden og hvilke parametere som påvirker lagringseffektiviteten i salinakviferer. Spesielt ble effekten av permeabilitet og ... -
Impact of seismic source/receiver directivity on sub-basalt imaging
(Master thesis, 2010)Many sedimentary basins considered for hydrocarbon exploration are overlaid by basalt layers which disrupts seismic wave propagation due to its properties. A single large gun has a nearly spherical directivity and at low ... -
The Impact of Shale Anisotropic Strength and Stiffness on Borehole Stability
(Master thesis, 2015)ABSTRACT Borehole instabilities is an expensive problem for the petroleum industry and most of the time, problems occur in shale. Shale is an anisotropic rock but most often it is assumed to be isotropic during borehole ... -
