Chemical and magnetic properties of rapidly cooled metastable ferri-ilmenite solid solutions: implications for magnetic self-reversal and exchange bias - III. Magnetic interactions in samples produced by Fe-Ti ordering
(Journal article; Peer reviewed, 2012)Paper II of this series described the chemical and microstructural evolution of ferri-ilmenite solid solutions during high-T quench and short-term annealing. Here we explore consequences of these Fe–Ti ordering-induced ... -
The chemistry of quartz in granitic pegmatites of southern Norway: Petrogenetic and economic implications
(Peer reviewed; Journal article, 2015)Trace element concentrations in quartz from 188 granitic pegmatites in the Froland and Evje-Iveland pegmatite fields, southern Norway, have been determined to establish exploration targets for high-purity quartz and to ... -
Circulating out minor influxes through open riser during dual gradient drilling with a partly evacuated riser
(Master thesis, 2012)Today, with conventional drilling technology, the cost of drilling deep and ultra-deepwater wells is very high, thus many reservoirs are classified as non-economical. Some reservoirs may also be impossible to reach with ... -
Classification and analysis of systems for Managed Pressure Drilling (MPD)
(Master thesis, 2010)Today, the petroleum industry faces more and more prospects that are technically impossible and economically unfeasible to drill with conventional methods. This is due to depletion of old reservoirs and increased water ... -
Classification of flotation frothers
(Journal article; Peer reviewed, 2018)In this paper, a scheme of flotation frothers classification is presented. The scheme first indicates the physical system in which a frother is present and four of them i.e., pure state, aqueous solution, aqueous solution/gas ... -
Classification of Icelandic Aggregates and Effect on Concrete Properties
(Master thesis, 2020)Tilslag er volummessig den største bestanddelen i betong og har stor påvirkning på betongens egenskaper. Naturlige sand- og grusforekomster er en begrenset ressurs i verden, og det er av avgjørende betydning å kjenne til ... -
Classifying Lithofacies from Textural Features in Whole Core CT-Scan Images
(Peer reviewed; Journal article, 2021)X-ray computerized tomography (CT) is a nondestructive method of providing information about the internal composition and structure of whole core reservoir samples. In this study we propose a method to classify lithology. ... -
Close range interactions between air guns
(Doktoravhandlinger ved NTNU, 1503-8181; 2013:293, Doctoral thesis, 2013) -
Closed-Form Solution to the Poromechanics of Deep Arbitrary-Shaped Openings Subjected to Rock Mass Alteration
(Peer reviewed; Journal article, 2020)The aim of this paper is to propose a closed-form solution to the poromechanics problem of stress and pore pressure distribution around noncircular openings at great depth subjected to hydrostatic water pressure and far-field ... -
CO2 Data Share: A Platform for Sharing CO2 Storage Reference Datasets from Demonstration Projects
(Journal article, 2019)Extensive research is ongoing worldwide to build competence and to develop cost-efficient technologies for safe injection and subsurface storage of CO2. Currently, the full potential of academic research is not realized ... -
CO2 Enhanced Oil Recovery in Strong Water-Drive Reservoirs
(Master thesis, 2012)The growing demand for energy has prompted oil companies to increase the production while paying more and more attention to the CO_2 footprint of their activities. To fulfill these requirements CO_2 storage and enhanced ... -
CO2 EOR Potential in the Brent Group at the Statfjord Field
(Master thesis, 2017)CO2 flooding is an enhanced oil recovery (EOR) technique that can be used to improve displace- ment efficiency and volumetric sweep efficiency. This is due to its favorable interactions with oil, which can be beneficial ... -
CO2 fluid flow information from quantitative time-lapse seismic analysis: Illustrated using seismic data from Sleipner, North Sea, Norway
(Doctoral thesis at NTNU;2015:308, Doctoral thesis, 2015) -
CO2 Injection in an Oil Reservoir with Gas Cap (Compositional Simulation Case at Heidrun Field Norway)
(Master thesis, 2006)A potential problem with CO2 Injection in oil reservoirs with gas caps is that gas cap may be contaminated by CO2. This could be an issue on the Heidrun Field where down dip using CO2-WAG is considered. Compositional ... -
CO2 saturation estimates at Sleipner (North Sea) from seismic tomography and rock physics inversion
(Journal article; Peer reviewed, 2018)CO2 saturations are estimated at Sleipner using a two‐step imaging workflow. The workflow combines seismic tomography (full‐waveform inversion) and rock physics inversion and is applied to a two‐dimensional seismic line ... -
CO2 Sequestration: The effect of carbonate dissolution on reservoir rock integrity.
(Master thesis, 2012)Since the environmental focus only becomes stronger and stronger in today’s society, industries like the oil and gas sector face some difficult challenges. Being the primary industry for CO2 production in the world requires ... -
CO2 STORAGE IN DEPLETED GAS FIELD RESERVOIR MODEL AND SENSITIVITY ANALYSIS USING NUMERICAL SIMULATION TECHNIQUES
(Master thesis, 2022)Worries are growing with the upsurge of GHG emissions and accumulation into our atmosphere where the chief producer of GHG is the combustion of fossil fuel for producing useful energy. Energy scientists, researchers and ... -
