The effect of nano-silica in oil-well cement
(Master thesis, 2013)A goal for all drilling operations is that they are performed within satisfactory safety- and financial boundaries. A big part of this is that the cementing operations are performed in a best possible manner, and having a ... -
The Effect of Salinity on Surfactant Flooding: A Literature Review and an Experimental Study
(Master thesis, 2013)Surfactant flooding is a proven EOR technique, which mobilizes residual oil by reducing interfacial tension (IFT). Several parameters affect the phase behaviour of a microemulsion system and a successful surfactant flooding ... -
The Effect of Small-Scale Heterogeneities on the Gas Distribution in the Tubåen Formation through Upscaling of CO2-Brine Relative Permeability
(Master thesis, 2017)The Tubåen Formation in the Norwegian Sea is an aquifer and was used by Statoil ASA as the injection reservoir for CO2 separated from produced gas at Snøhvit in the time period between April 2008 until it was abandoned in ... -
The effects of seismic anisotropy and upscaling on rock physics interpretation and AVO analysis
(Master thesis, 2015)In seismic reservior characterization, it is important that the measured sonic log used is accurate and consistent. Due to anisotropic effects in the reservoir, which is majorly caused as a results of interbedded sequence ... -
The effects of subsurface uncertainty on economic risk when developing the Mackerel satellite field in the North Sea
(Master thesis, 2019)Denne oppgaven undersøker effekten av usikkerhet i et lite Nordsjøfelt på om det er økonomisk forsvarlig å bygge det ut basert på produksjon, utvinningsgrad og endelig nåverdi (NPV) og internrente (IRR). To usikkerhetsfaktorer ... -
The engineering of petroleum streams
(Doctoral thesis, 2002)In a multidisciplinary petroleum industry using a wide variety of engineering software, consistent and easy transfer of quantitative data related to petroleum streams is a major issue. Making it more difficult is the lack ... -
The EU "PARTNER" Project - European standard tests to prevent alkali reactions in aggregates: Final results and recommendations
(Journal article; Peer reviewed, 2010)This paper presents the main findings in the EU PARTNER Project (2002–2006) providing the basis for a unified European test approach for evaluating the potential alkali-reactivity of aggregates. The project evaluated the ... -
The evolution of the Triassic bivalve Daonella into Halobia in the Botneheia Formation on Svalbard - a sedimentological and palaeoenvironmental interpretation
(Master thesis, 2017)The Svalbard Triassic succession represents an uplifted section of a broad epicontinental shelf at the north-eastern margin of Pangea. The Botneheia Fm. of the Middle Triassic is an organic carbon-rich bituminous shale, ... -
The family resemblance of technologically mediated work practices
(Journal article; Peer reviewed, 2012)Practice-based perspectives in information systems have established how, in every instance of use (i.e., work practices), the user exercises considerable discretion in their appropriation of the technology with local ... -
The Geochemistry of the Topsoil in Oslo, Norway
(Dr.ingeniøravhandling, 0809-103X; 2003:33, Doctoral thesis, 2003)In co-operation with the Geological Survey of Norway, 395 samples of topsoil, 44 bedrock samples and 24 samples of sand from sandboxes at kindergartens taken in Oslo, the capital city of Norway, were analysed for a wide ... -
The Håkåneset rockslide, Tinnsjø - Stability analysis of a potentially rock slope instability.
(Master thesis, 2014)The Håkåneset rockslide is located on the west shore of Lake Tinnsjø (191 m.a.s.l), a fjordlake stretching 32 km with a SSE-NNW orientation in Telemark, southern Norway. The instability extends from 550 m.a.s.l. and down ... -

The history of exploration and stratigraphy of the Early to Middle Triassic vertebrate-bearing strata of Svalbard (Sassendalen Group, Spitsbergen)
(Journal article; Peer reviewed, 2018)The palaeontology of the Lower to Middle Triassic succession in Spitsbergen has been studied for more than a century and a half. Our ability to properly interpret the evolutionary and ecological implications of the faunas ... -
The Impact of Nanoparticle Adsorption on Transport and Wettability Alteration in Water-Wet Berea Sandstone: An Experimental Study.
(Journal article; Peer reviewed, 2019)Wettability alteration was proposed as one of the enhanced oil recovery (EOR) mechanisms for nanoparticle fluid (nanofluid) flooding. The effect of nanoparticle adsorption on wettability alteration was investigated by ... -
The impact of saturation on seismic dispersion in shales — Laboratory measurements
(Journal article; Peer reviewed, 2018)Previous studies found a significant increase of acoustic velocities between seismic and ultrasonic frequencies (seismic dispersion) for shales, which would have to be taken into account when comparing seismic or sonic ... -
The implications of sulphides in GCC feed and the potential for their removal during alkaline amine flotation
(Doctoral thesis at NTNU;2015:59, Doctoral thesis, 2015)Ground calcium carbonate (GCC) slurries are commonly used in paper to improve properties such as whiteness, printability, opacity and gloss. The brightness R457 (i.e. the reflectance at a wavelength of 457 nm) and colour ... -
The Importance of Low-end-rheology and its Influence on Particle Slip Velocity
(Master thesis, 2013)The study of effective cuttings transports and understanding fluid rheological properties is a major concern in the drilling industry. Poor hole cleaning can lead to cuttings accumulations inside the annulus, low rate of ... -
