Wellbore stability analysis for an extended-reach well on Ekofisk
(Master thesis, 2022) -
Wellbore stability and rock mechanics study on the Ula field
(Masteroppgave/UIS-TN-IPT/2013;, Master thesis, 2013-06-20)In the years to come more challenging drilling conditions will occur when the last reserves need to be collected. More directional drilling will be used and good wellbore conditions will be necessary to make this possible. ... -
Wellhead Fatigue Analysis : Surface casing cement boundary condition for subsea wellhead fatigue analytical models
(;163, Doctoral thesis, 2012-05-31)Material fatigue is a failure mode that has been known to researchers and engineers since the 19th century. Catastrophic accidents have happened due to fatigue failures of structures, machinery and transport vehicles. ... -
Wet Drilled Cuttings Bed Rheology
(Peer reviewed; Journal article, 2021)The cuttings transport efficiency of various drilling fluids has been studied in several approaches. This is an important aspect, since hole cleaning is often a bottleneck in well construction. The studies so far have ... -
Wet-granular rheology to measure cuttings-bed strength
(Peer reviewed; Journal article, 2021)Drilled cuttings-bed formation is a natural process during wellbore drilling operations, although it is not desired. To optimally remove the drilled cuttings out of the wellbore it is important to break the formed beds. ... -
Wettability alteration in carbonates : the effect of water-soluble acids in crude oil and application of enzyme for wettability alteration
(Masteroppgave/UIS-TN-IPT/2010;, Master thesis, 2010)The objective of the project is defined in two phases. The first phase is to study the effect of oil composition and carboxylic acids in the crude oil on the wetting condition and wettability alteration process using ... -
Wettability alteration in carbonates: the effect of water-soluble carboxylic acids in crude oil
(Journal article; Peer reviewed; Doctoral thesis, 2010)Acidic components in crude oil influence the wetting condition through their effect on electrostatic interactions with the mineral surfaces. In this paper, we have extracted water-soluble acids from a crude oil with a high ... -
Wettability in chalk, effect of initial water saturation on the adsorption of polar oil components
(Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06)Experimental study of wettability alteration was aimed at three laboratory designated chalk material, collected from the same reservoir block, at different initial water saturations (0%, 10%, and 40%). Crude oil sample ... -
Wettability in chalk, effect of temperature on the adsorption of the acidic components in crude oil
(Masteroppgave/UIS-TN-IØRP/2013;, Master thesis, 2013)The initial wetting of carbonate reservoirs will affect the overall oil recovery and the potential of EOR methods linked to wettability alteration by the generation of positive capillary pressure. Polar acids in oil also ... -
What are the costs of currency hedging for Norwegian high yield funds, and what is the optimal hedge strategy to limit these costs?
(Master thesis, 2021)As Norwegian high yield funds invest in foreign denominated assets, a risk associated with the exchange rate fluctuations occur and adds to the underlying risk of the asset. A common approach to this added risk is to utilize ... -
What are the effects of changing the test interval of land based safety critical valves in hydrocarbon transport systems
(Masteroppgave/UIS-TN-IØRP/2008, Master thesis, 2008)In this master thesis, the effects of changing the test interval of the land based safety critical valves have been highlighted. Compliance with the regulations given by the PSAN (Petroleum Safety Authority Norway) ... -
What are the site related and most sensitive parameters to optimize a large-scale PV installation at Stavanger Airport?
(Masteroppgave/UIS-TN-ISØP/2020;, Master thesis, 2020-06)The climate and energy problems are on the rise as the urban population is growing rapidly. The extensive use of fossil fuels and the increasing greenhouse gas (GHG) emissions still awaits collective abatement policies. ... -
What is driving the Bitcoin market?
(Masteroppgave/UIS-TN-ISØP/2020;, Master thesis, 2020-06)The Bitcoin market has grown to become relevant to financial markets and there are still a number of unanswered questions relating to Bitcoin as an asset class and how the Bitcoin market behave relative to traditional ... -
What is energy storage, and how can this contribute to large-scale integration of renewable energy?
(Masteroppgave/UIS-TN-IØRP/2011;, Master thesis, 2011)Energy represents a very formative need in the world today, produced mainly from fossil resources with consequences as climate change, community interference, and worries about limited energy reserves. Hence, renewable ... -
What is Risk Culture, and Why Do We Need It?
(Master thesis, 2023)Hybrid threats dominate our contemporary and technological society, and new risks can be challenging to predict because of today’s digitization. As modern safety-critical organizations and their technologies become more ... -
What we can learn from ALARP regulation?
(Master thesis, 2021)Potential hazards exist in almost all workplaces. The existence of these hazards can result in accidents or incidents that have an impact on people, equipment, materials, and the environment. To get the proper and good ... -
"When Communication is key" An evaluation of Risk communication from FHI during the initial stage of the Covid-19 pandemic and how can the communication have made implications in peoples risk perception?
(Master thesis, 2022)Hensikten med denne masteroppgaven har i hovedsak vært å undersøke hvordan FHI gjennomførte sin risikokommunikasjon i initialfasen til Covid-19 pandemien da Norge måtte stenge ned. I tillegg har det blitt sett på om denne ... -
When counterterrorism enters the curriculum: Exploring risks and practices of the securitisation of education
