Reduced well path parameterization for optimization problems through machine learning
(Peer reviewed; Journal article, 2021)In this work we apply a recently developed machine learning routine for automatic well planning to simplify well parameterization in reservoir simulation models. This reduced-order parameterization is shown to be beneficial ... -
Reducing high-frequency ghost cavitation signals from marine air-gun arrays
(Journal article; Peer reviewed, 2016)Ghost cavitation, which is a term describing that cavitation bubbles are generated acoustically, has been hypothesized to occur when the ghost reflected signals from many individual air guns beneath the sea surface produce ... -
Regional geological seismic interpretation of Triassic infill in the southwestern Barents Sea
(Master thesis, 2013)The Barents Sea has been subject to increasing focus through the years due to the discoveries of e.g. Havis, Skrugard and Nordvarg, which show some of the potential of the area. Despite 30 years of exploration large parts ... -
Regional net erosion estimations and implications for seismic AVO signatures in the Western Barents Sea
(Master thesis, 2016)The south western Barents Sea has a complex burial and uplift history with episodes linked both to local extension and regional episodes affecting the entire area. The most significant exploration problem relates to the ... -
Regional sea-level highstand triggered Holocene ice sheet thinning across coastal Dronning Maud Land, East Antarctica
(Peer reviewed; Journal article, 2022)The East Antarctic Ice Sheet stores a vast amount of freshwater, which makes it the single largest potential contributor to future sea-level rise. However, the lack of well-constrained geological records of past ice sheet ... -
Regional Tectonic and Environmental Assessments of the Norwegian Polar Regions using Potential Field Methods
(Doctoral theses at NTNU;2021:421, Doctoral thesis, 2021)Interest for the polar regions has increased during the last few decades. New technologies now allow to conduct research in this hostile environment. Tectonic history and timing of the opening of the Arctic is the key to ... -
Regionalstudie i det vestlige Barentshavet - Relatere kartlagte strukturer fra Kenozoikum til åpningen av havet mellom Norge og Grønnland
(Master thesis, 2016)Denne studien omfatter en regionalstudie av den Kenozoiske lagrekken i det vestlige Barentshavet. Området omfatter Sørvestnaget Bassenget og den nordvestlige delen av Vestbakken Provinsen. Seismiske 2D data levert av ... -
Relating acoustic wave velocities to formation mechanical properties
(Master thesis, 2012)Proper correlation between formation mechanical properties and acoustic data is essential for acquiring field rock mechanical data for analysis, and it has thereby a great significance to oilfield development.This thesis ... -
Relating Static and Dynamic Mechanical Anisotropies of Shale
(Chapter, 2015)Experimental studies of shale cores of different orientations have been performed to compare the angular dependence of dynamic moduli acquired at ultrasonic frequencies with static moduli (Young’s moduli and Poisson ratios) ... -
Relations between Static and Dynamic Moduli of Sedimentary Rocks
(Journal article; Peer reviewed, 2018)Static moduli of rocks are usually different from the corresponding dynamic moduli. The ratio between them is generally complex and depends on several conditions, including stress state and stress history. Different drainage ... -
Relationship between environmental conditions and magnetic properties of Norwegian black shales
(Master thesis, 2018)As part of a project to describe organic rich black shales from the Upper Jurassic from the Hekkingen Formation on the Norwegian shelf, cores 7430/10-U-01 North from the Nordkapp Basin (NE Barents Sea) and 7018/05-U-01 ... -
Reliable Unmanned Autonomous Systems: Conceptual Framework for Warning Identification during Remote Operations
(Journal article, 2021)In the offshore industry, unmanned autonomous systems are expected to have a permanent role in future operations. During offshore operations, the unmanned autonomous system needs definite instructions on evaluating the ... -

Relief Well Killing In Shallow Reservoirs
(Master thesis, 2015)After the "Wisting"-discovery was made in the Barents sea, operators are likely to be more aware of the potential in shallower formations when planning exploration wells. With the possible development of more shallow ... -
Remote Sensing Analysis of Lacustrine Carbonates, Namibe
(Master thesis, 2011)This thesis involves analysis of multispectral (Aster images) and field data to identify hydrothermal rocks such as travertines associated with two stages of volcanism from (Precambrian 122ma) and from (Cenomanian-Turonian88ma) ... -

Reservoir Characterization and Determination of Residual Oil Saturation Using Single-Well- Chemical-Tracer Test - Significance of Geochemistry, Rock Dissolution, and Surface-Charge Alteration
(Doctoral theses at NTNU;2017:350, Doctoral thesis, 2017)It is generally recognized that the determination of residual oil saturation (Sor) plays a significant role in production forecasting and the selection and management of enhanced oil recovery (EOR) methods. Failure to ... -
Reservoir characterization and impacts of diagenesis on Upper Cretaceous sandstone formations in the Norwegian Sea, well 6707/10-1
(Master thesis, 2016)The study of deep marine sandstone is among the main research of hydrocarbon explorations now a days. The diagenetic alterations and impacts of diagenesis on reservoir quality of the deep marine sandstone are relatively ... -
Reservoir Characterization of Rogn Formation sandstones in the southern part of the Froan Basin Offshore Mid-Norway.
(Master thesis, 2017)Jurassic reservoirs offshore mid- Norway are of extreme importance in the Norwegian oil and gas sector. Petrophysical logs and thin sections of two cores from southern Froan Basin (Offshore mid-Norway) are investigated to ...
