The Hambergfjellet Formation on Bjørnøya – sedimentary response to early Permian tectonics on the Stappen High
(Peer reviewed; Journal article, 2023)On Bjørnøya, the exhumed crest of the Stappen High, the lower Permian (Cisuralian) Hambergfjellet Formation represents the only exposed part of the Bjarmeland Group carbonate platform, which occurs widely elsewhere in the ... -
Handling of Gas Kick Using the Low Riser Return System

Head Race Tunnel Melado Hydropower Plant, Chile: Optimization in Excavation and Rock Support
(Master thesis, 2012)The present thesis is to focus on the two head race tunnels within the Melado HPP, Chile. The upstream tunnel is called Castillo 7800 m long and the downstream tunnel is called Vallical 8800 m long.The feasibility study ... -
Heat Flow and Deep Underground Temperature in the Bergen Region
(Master thesis, 2011)Anomalously high concentrations in radioactive elements have been recently discovered in the Løvstakken Granite, southwest of downtown Bergen. Because it potentially implies radon hazard, this latter discovery has raised ... -
Heat from the ground and sun: An energy-optimizing project at Mære Landbruksskole
(Master thesis, 2010)Grunnvarme som ein kilde til lagring og uttak av varme kan redusere utslepp av CO2 til atmosfæren betrakteleg og samtidig føre til økonomiske gevinster. Utfordringa ligg i å senke kostnadar til installasjon og drift av ... -
Heat Transfer – Between Rock Mass and Tunnel Room
(Master thesis, 2019)Bruk av tunnelkledning uten frostsikring er en økende trend, spesielt i jernbane tunneler. Dette er metoder som er lite brukt i Norge tidligere, og dermed er det også minimalt med kunnskap om hvordan kledningen faktisk ... -
Heave Compensated Managed Pressure Drilling: Lab Experiments
(Master thesis, 2013)The world energy demand is ever increasing with every year. Oil and gas make up approximately 55% of energy sources to meet the demand. However, hydrocarbons reserves are limited and according to peak oil theory, the peak ... -
HeaveLock - A New System For Reduced Surge And Swab Pressure For Floating Drilling Operations
(Master thesis, 2016)Managed pressure drilling is only carried out from fixed installation in harsh environments today. Rig heave is compensated with top drive compensation system under drilling or tripping of pipe. During connections the ... -
HeaveLock - Enabling MPD On Floating Drilling Vessels
(Master thesis, 2016)During drilling operations from floating drilling vessels, it is often experienced challenges related to heave motions when the rig s heave compensating system is deactivated. Rig heave movements cause the bottom hole ... -
Heavy Oil Production Technology Challenges and the Effect of Nano Sized Metals on the Viscosity of Heavy Oil: A literature review and an experimental study
(Master thesis, 2013)Heavy oil and bitumen make up 70% of the discovered petroleum resources in the world. Only a very small fraction of these resources have so far been produced, as the recovery techniques available for heavy crudes and oil ... -
Heptanes-Plus Characterization Based on the PNA content
(Master thesis, 2019) -
Heterocoagulation of shale particles and bubbles in the presence of ionic surfactants
(Journal article; Peer reviewed, 2018)Adsorption of surfactants is one of the important feature governing interactions between particulate matters. When interactions occur between two particulates, which differ from each other, heterocoagulation takes place. ... -
Hierarchical Clustering Combination and an Algorithm to Solve the Tanglegram Layout Problem
(Master thesis, 2021)I petroleumsgeologifeltet har ulike tilnærminger til maskinlæring vist at det finnes et substansielt potensial som kan supplere og på sikt erstatte konvensjonelle og arbeidsintensive metoder. Noen forfattere har for eksempel ... -
High frequency ghost cavitation - a comparison of two seismic air-gun arrays using numerical modeling
(Journal article; Peer reviewed, 2017)Ghost cavitation is probably the mechanism behind the majority of high frequencies (above 5 kHz) generated by seismic air-gun arrays. Such high frequencies are less important in seismic reflection imaging. High frequency ... -
High resolution reflection seismic profiling over the Tjellefonna fault in the More-Trondelag Fault Complex, Norway
(Journal article; Peer reviewed, 2012)The Møre-Trøndelag Fault Complex (MTFC) is one of the most prominent fault zones of Norway, both onshore and offshore. In spite of its importance, very little is known of the deeper structure of the individual fault segments ... -
High salinity and high temperature stable colloidal silica nanoparticles with wettability alteration ability for EOR application.
(Peer reviewed; Journal article, 2021)The stability of nanoparticles at reservoir conditions is a key for a successful application of nanofluids for any oilfield operations, e.g., enhanced oil recovery (EOR). It has, however, remained a challenge to stabilize ... -
High velocity flow in a fractal reservoir
(Chapter, 2010) -
High-dimensional separability for one-and few-shot learning
(Peer reviewed; Journal article, 2021)This work is driven by a practical question: corrections of Artificial Intelligence (AI) errors. These corrections should be quick and non-iterative. To solve this problem without modification of a legacy AI system, we ... -
High-pressure experiments with application to naturally fractured chalk reservoirs
(Dr. ingeniøravhandling, 0809-103X; 1992:97, Doctoral thesis, 1992) -
High-resolution Meso- and Microstructural Study of polyphase Deformation in the Orkanger Region, Sør-Trøndelag, Central Norway
(Master thesis, 2015)The Orkanger Road Cut (ORC) is a 300 m long section of exposed country rock that has preserved an important record of structures linked to the tectonic history of the Mid-Western Gneiss Region. High-resolution field mapping ...
