Optimized Smart Water Composition at Ekofisk Conditions
(Masteroppgave/UIS-TN-IER/2020;, Master thesis, 2020-12)Seawater has been performing as a wettability modifier in chalk reservoirs and has been used for this purpose for a long time. This wettability alteration enhances microscopic then overall displacement efficiencies. Having ... -
Optimizing carbonate core restoration procedures - Effect of crude oil saturation and mild cleaning
(Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-06-15)Wettability has a big impact on how much we can recover by water flooding a reservoir, and there is a commercial potential for improvement done through alteration of the wettability. Studies have been conducted and shown ... -
Optimizing Document Classification: Unleashing the Power of Genetic Algorithms
(Peer reviewed; Journal article, 2023)Many individuals, including researchers, professors, and students, encounter difficulties when searching for scholarly documents, papers, and journals within a specific domain. Consequently, scholars have begun to focus ... -
Optimizing formulations for reservoir drilling fluids
(Bachelor thesis, 2022)When drilling a well, equivalent circulation density exceeding the fracture gradient can cause lost circulation. In a reservoir section, invasion of drilling fluids can potentially cause a permanent permeability reduction ... -
Optimizing of Rack and Pinion System for Valve Intervention Tool
(Bachelor thesis, 2023)Hensikten med denne oppgaven er å se på forbedringer av rack- og pinion systemet som brukes i Izomax's isolasjonsverktøy Add On Gate Valve (AOGV). Dette systemet blir brukt til å sette inn en blindspade mellom to flenser ... -

Optimizing support vector machines and autoregressive integrated moving average methods for heart rate variability data correction
(Peer reviewed; Journal article, 2023-09)Heart rate variability (HRV) is the variation in time between successive heartbeats and can be used as an indirect measure of autonomic nervous system (ANS) activity. During physical exercise, movement of the measuring ... -
Optimizing the installation process for future FOW developments in Europe, using Shoreline
(Master thesis, 2021)The increasing interest and demand for renewable energy in Europe have supported trials and developments of floating offshore wind turbines in deep waters. It is already well established that about 80% of Europe's potential ... -
Optimizing the separation factor along a directional well trajectory to minimize collision risk
(Peer reviewed; Journal article, 2020-04)Optimizing the trajectory of directional wellbores is essential to minimize drilling costs and the impacts of potential drilling problems. It poses multi-objective optimization challenges. Well-design optimization models ... -
Optimum directional well path design considering collapse and fracture pressures
(Peer reviewed; Journal article, 2022)Well path optimisation is often done based on the wellbore stability where the production related concerns are ignored. In fact, many of the studies carried out in the past have not included hydraulic fractures into their ... -
OptiRun - A Platform for Optimized Test Execution in Distributed Environments
(Masteroppgave/UIS-TN-IDE/2016;, Master thesis, 2016-06)Computer systems have grown to play an essential role in our society. Software testing is an important asset of the software development process, as it serves to evaluate the quality of the software object being tested. ... -
Orchestration and Control in Software-Defined 5G Networks: Research Challenges
(Journal article; Peer reviewed, 2018-08)The fifth generation (5G) of cellular networks promises to be a major step in the evolution of wireless technology. 5G is planned to be used in a very broad set of application scenarios. These scenarios have strict ... -
Order parameter dynamics of the non-linear sigma model in the large N limit
(Peer reviewed; Journal article, 2020)We study non-equilibrium order parameter dynamics of the non-linear sigma model in the large N limit, using Keldysh formalism. We provide a scheme for obtaining stable numerical solution of the Keldysh saddle point equations ... -
Organic flow assurance, pour point depressant development through experimental design
(Masteroppgave/UIS-TN-IMN/2012;, Master thesis, 2012-07-03)Flow assurance is of great importance in the oil and gas industry, where the main objective is to provide and secure the transport of the well stream fluid from the reservoir to the process facilities. The main challenges ... -
Organic flow assurance: Asphaltene dispersant/inhibitor formulation development through experimental design
(Masteroppgave/UIS-TN-IMN/2012;, Master thesis, 2012)The exploitation of hydrocarbon has forced the petroleum production to move closer to extreme climate areas and deep waters such as the Barents Sea. These challenges require effective and safe production, transport and ... -
Organisatorisk håndtering av storulykkerisiko
(Masteroppgave/UIS-TN-IØRP/2014;, Master thesis, 2014-09-12)Bakgrunn: Risikobegrepet blir i dag brukt i mange sammenhenger og med forskjellig og ofte uklar betydning. Vår oppfatning og forståelse av risiko har betydning for hvordan en handler for å styre sikkerhet og risiko (Aven, ... -
Organiseringen av responsen etter eksplosjonen i Beirut
