Experimental Studies on North Sea Rock Evaluating the Low Salinity Effect on Enhanced Oil Recovery and Permeability Reductions
(Master thesis, 2011)In this project the concept of low salinity water flooding is experimentally tested and discussed. Both the effect on enhanced oil recovery and the permeability reductions issues which can arise during low salinity flooding ... -
Experimental study and CFD simulation of water coning phenomenon in perforated geometry
(Master thesis, 2016)The focus of this thesis is to further examine the water coning phenomenon in annular geometry in a horizontal well completion. This phenomenon is of particular interest to the oil & gas industry, as it may restrict ... -
Experimental study and stress analysis of rock bolt anchorage performance
(Journal article; Peer reviewed, 2014)A new method was developed to apply pull-and-shear loads to the bolt specimen in order to evaluate the anchorage performance of the rebar bolt and the D-Bolt. In the tests, five displacing angles (0°, 20°, 40°, 60°, and ... -
Experimental Study for Wear Characteristics and Wear Prediction of Corrosion Resistant Alloy Material Tubulars
(Master thesis, 2022)Precise casing wear estimation is important to ensure appropriate well integrity and safer production of hydrocarbons. The amount of casing wear depends not only on operational parameters but also on the casing material. ... -
Experimental study into the overtopping and breaching of rockfill dams with erosion protection
(Master thesis, 2022)Embankment dams are mainly made of erodible and pervious materials and are at risk from overtopping and piping, the erosion process that initiates may ultimately lead to the dam breaching. Estimating the flood and mapping ... -
Experimental study of a Francis turbine under variable-speed and discharge conditions
(Journal article; Peer reviewed, 2018)This work investigates the unsteady pressure fluctuations in a hydraulic turbine that are observed during steep ramping. Although hydraulic turbines are expected to operate seamlessly during steep ramping, the resulting ... -
Experimental Study of a Low-Specific Speed Francis Model Runner during Resonance
(Journal article; Peer reviewed, 2018)An analysis of the pressure in a runner channel of a low-specific speed Francis model runner during resonance is presented, which includes experiments and the development of a pressure model to estimate both the convective ... -
An experimental study of an ejector-boosted transcritical R744 refrigeration system including an exergy analysis
(Peer reviewed; Journal article, 2021)The field of refrigeration witness a massive transition in the supermarket with a strong focus reflected on energy consumption. The use of ejector allows for overcoming the significant exergy destruction lays on the expansion ... -
Experimental study of an offshore aquaculture cage concept
(Master thesis, 2023)Behov for bærekraftig matproduksjon øker betydelig i takt med en økt global befolkning og global oppvarming. Nye klimavennlige løsninger må integreres og utvikles for å møte den økende etterspørselen etter mat, hvor ... -
An experimental study of beam-columns subjected to combined torsion, bending and axial actions
(Doktor ingeniøravhandling;1995:66, Doctoral thesis, 1995)This report presents an investigation on the inelastic behaviour of steel I-section beam-columns under combinations of axial load, bending and torsion. The study is motivated by the lack of information on the ultimate ... -
Experimental study of bubble characteristics and heat transfer in subcooled flow boiling of R-134a
(Master thesis, 2013)Because of its high heat transfer efficiency, subcooled flow boiling can contribute to the miniaturization of subsea heat exchangers. An experimental investigation was conducted to study the parametric influence on the ... -
Experimental Study of Cement-Formation Bonding
(Master thesis, 2013)This experimental work is the continuation of the literature study of cement-formation bonding, done in the autumn semester. Cement-formation bonding has not been given special attention so far, in resolving the well ... -
Experimental study of channel flow with sinusoidal walls using stereo-PIV
(Master thesis, 2021)Et eksperiment har blitt designet for å utforske resultatene til Brostrøm, Holum, Akselsen og Ellingsen i første omgang, og masteroppgaven kan bli sett på som en fortsettelse av dette arbeidet (Brostrøm, 2020, ... -
Experimental study of concrete-ice abrasion and concrete surface topography modification
