Plugging and Abandoning Subsea Wells Using Light Well Intervention Vessels
(Master thesis, 2016-06-15)There are thousands of subsea wells in the world. The subsea industry is growing, more and more subsea wells are being developed. When the wells are no longer used, usually because they become unproductive, they need to ... -
The Polar Code's Implications for Safe Ship Operations in the Arctic Region.
(Peer reviewed; Journal article, 2020-09)ABSTRACT: Simultaneously with a decreasing sea ice cover in the Arctic region an increase in ship traffic is experienced in these waters, meaning a higher probability of accidents and incidents to occur. The capability to ... -
Polar Ship Design and Operations: Past, Present, and Future
(Chapter, 2022)From an early emphasis on geographic exploration and exploitation of the resources in the polar offshore area (by hunting for walrus ivory teeth, seals, and whales), the focus is currently shifting toward the sustainable ... -
Politics of climate risk management in local government: A case study of the municipality of Stavanger
(Peer reviewed; Journal article, 2023-07)The case study presented in this paper was conducted to study the politics of local-level climate risk management and discuss these politics' implications for responses to climate change and democratic deliberation. Local ... -
Politiet i nasjonal krisehåndtering
(Masteroppgave/UIS-TN-ISØP/2019;, Master thesis, 2019-06-10)Sammendrag Bakgrunn og formål Politiet skal sikre samfunnets og befolkningens rettssikkerhet, trygghet og alminnelig velferd. Oppgaven skal løses ut fra en formell desentralisert ledelse av politioperativ innsats. ... -
Politiets håndtering av uforutsette skarpe oppdrag. "Hvordan har politiets evne til å håndtere skarpe oppdrag på taktisk nivå endret seg siden 22. juli-angrepene 2011?"
(Masteroppgave/UIS-TN-ISØP/2020;, Master thesis, 2020-05)Etter 22. juli-angrepet mot ungdommene på Utøya, ble det rettet mye kritikk mot politiet og myndighetene. Rapporten fra 22. juli-kommisjonen sa blant annet at gjerningsmannen kunne ha vært pågrepet tidligere. Det gikk en ... -
Polysulphate as Smart Water Additive for Improved Oil Recovery from Carbonate Reservoirs
(Master thesis, 2022) -
Polysulphate: A New Enhanced Oil Recovery Additive to Maximize the Oil Recovery From Carbonate Reservoirs at High Temperature
(Peer reviewed; Journal article, 2022)Seawater (SW) injection is an enhanced oil recovery (EOR) success in the North Sea carbonate reservoirs due to wettability alteration toward a more water-wet state. This process is triggered by the difference in composition ... -
Polytopisk quasi-LPV modellering, identifikasjon og LQR regulering av en Quanser Aero
(Bachelor thesis, 2022)Denne avhandlingen beskriver utviklingen av en quasi-LPV modell for et laboratorieoppsett med to frihetsgrader, kalt Quanser Aero. Quasi-LPV modellen er utviklet med bakgrunn i en ulineær dynamisk modell av Aero systemet. ... -
Polyurethane sealing discs on cleaning pigs-characterization and dynamic behaviour
(Masteroppgave/UIS-TN-IKM/2015;, Master thesis, 2015-06-15)Pipeline pigging enhances flow rate and corrosion control. Pigging is made possible by the sealing element of the pig, of which polyurethane is the chief material used. Polyurethane raw materials are; polyols, isocyanates, ... -
Poncelet's Theorem
(Masteroppgave/UIS-TN-IMF/2018;, Master thesis, 2018-10)This thesis will be concerned with different questions related to the theorem of Poncelet. We will study the historical background of the theorem and learn theory needed to understand two different proofs. -
POP induced oxidative stress and its effect on fatty acid composition in Atlantic Cod (Gadus morhua) mitochondria
(Masteroppgave/UIS-TN-IMN/2010;, Master thesis, 2010)The North Sea is becoming heavily contaminated by organic pollutants. The dominating sources of contamination are land-based releases, transport and offshore oil and gas industry. This creates a complex spectrum of different ... -
Pore scale modeling of capillary pressure curves in 2D rock images
(PhD thesis UiS;213, Doctoral thesis, 2013-12-10)Capillary pressure is relevant to most processes of multiphase flow inporous media, as it controls the pore scale fluids distribution. Reliable capillary pressure curves are required to model and predict larger-scale ... -
Pore-scale Ostwald ripening of gas bubbles in the presence of oil and water in porous media
(Peer reviewed; Journal article, 2023)Hypothesis Ostwald ripening of gas bubbles is a spontaneous mass transfer process that can impact the storage volume of trapped gas in the subsurface. In homogeneous porous media with identical pores, bubbles evolve toward ... -
Porosity and permeability development in compacting chalks during flooding of nonequilibrium brines: Insights from long-term experiment
(Journal article; Peer reviewed, 2015-05)We report the complete chemical alteration of a Liège outcrop chalk core resulting from a 1072 flow-through experiment performed during mechanical compaction at 130°C. Chemical rock-fluid interactions alter the volumetric ... -
Porosity Evolution during Chemo-Mechanical Compaction
(Chapter, 2018)This chapter presents the constitutive equations necessary to interpret laboratory and field data when both solid and pore volume evolve through time due to chemical and mechanical processes. The equations for the porosity ... -
Porosity prediction from seismic data of the F3 block, offshore Netherlands, through seismic inversion and machine learning
(Master thesis, 2022)Porosity is a key rock property that influences reservoir quality and plays an important role in petroleum exploration and production. The most common sources of information for reservoir characterization are well and ... -
