Water-based enhanced oil recovery (EOR) by “Smart Water”: optimal ionic composition for EOR in carbonates
(Journal article; Peer reviewed; Doctoral thesis, 2011)The composition of the injecting brine has a profound effect on the efficiency of water-based enhanced oil recovery (EOR) methods. Recently, we observed that not only is the concentration of the active ions Ca2+, Mg2+, ... -
Water-Based EOR in Limestone by Smart Water : A study of surface chemistry
(PhD thesis UiS;147, Doctoral thesis, 2011-12-09) -
Waterflooding of carbonate reservoirs : EOR by wettability alteration
(PhD thesis UiS;50, Doctoral thesis, 2008-05-30)Oil production is generally divided into three stages, primary recovery, secondary recovery and tertiary recovery. In primary recovery, which is usually (but not necessarily) the first production stage, the natural energy ... -
Wave energy converter
(Masteroppgave/UIS-TN-IKM/2012;, Master thesis, 2012)The principal objective of this thesis has been to study and research on Water Energy Convertors(WEC) devices, carrying out theoretical and analytical approximations. Nowadays, the demand of renewable energy resources is ... -
Wave Influenced Wind and the Effect on Offshore Wind Turbine Performance
(Journal article; Peer reviewed, 2014)In this paper the effect of wave influenced wind on offshore wind turbines is studied numerically. The wave is seen as a dynamical roughness that influences the wind flow and hence the wind turbine performance. An actuator ... -
Wave-equation migration velocity analysis of the successive vintages of the Sleipner Field - A detailed prediction of the mechanical effects caused by CO2 injection
(Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-06-14)Since September 1996, Statoil and partners have through their carbon capture and storage project at the Sleipner field, located in the central North Sea, injected approximately one million tons carbon dioxide per year into ... -
Weak solutions for a gas liquid model relevant for describing gas-kick in oil wells
(Journal article; Peer reviewed, 2011)The purpose of this paper is to establish a local in time existence result for a compressible gas-liquid model. The model is a drift-flux model which is composed of two continuity equations and one mixture momentum equation ... -
Weakly interacting dark matter miracle
(Bachelor thesis, 2022)Dark matter is currently actively searched for in particle physics. In this thesis the weakly interacting massive particles (WIMPs) are looked at as possible dark matter candidates. The thesis focus on the mechanism called ... -
Weather Risk In Marine Operations: An Approach For Using Risk Indicators From Offshore Environment Perspective
(Masteroppgave/UIS-TN-IØRP/2016;, Master thesis, 2016-06)The safety of marine operations is largely dependent on the weather conditions. The conditions which exist at the location of operations, during the period when the operations are planned for execution, determine the ... -
Weather sensitivity of maritime activities on Chinese Shelf
(Masteroppgave/UIS-TN-IKM/2013;, Master thesis, 2013-10-03)The objective of the thesis is to discuss the weather sensitivity of maritime activities, inter alia, with respect to the aspects of passage planning, load plan-making, and ship maneuvering. As maritime activities represent ... -
Web application for energy system
(Bachelor thesis, 2023)This bachelor thesis describes the development of a web application that allows users to configure and save simulations for an energy system. The application utilizes a pre-existing simulator pack to generate real-time ... -

A web based solution to track trawl vessel activities over pipelines in Norwegian Continental Shelf
(Peer reviewed; Journal article, 2019)Vessel activities such as trawling and anchoring potentially affect pipeline integrity. Therefore, the detailed information about the trawl activity in the area is essential for accurate assessment of pipeline, where to ... -
WebAssembly for systemprogrammering
(Bachelor thesis, 2021)Med lanseringen av en ny standard har WebAssembly vært en økende trend blant utviklere. Primært har stasjonære og mobile nettlesere full støtte for WebAssembly per i dag. Det gir mange fordeler når den kjøres inne i ... -

Webgrensesnitt til tidslinjedatabase
(Bachelor thesis, 2023)En tidslinje er en serie av hendelser over et hendelsesforløp. Dette hendelsesforløpet kan deles i mindre tidsintervaller der et nytt tidsintervall starter når det skjer en endring i en av aktivitetene som tidslinjen ... -

The Weighted Kalman Filter
(Peer reviewed; Journal article, 2023)This paper proposes a new version of the Kalman filter, referred to as weighted Kalman filter (WKF). In the WKF some recent results on the weighted linearization of nonlinear systems are exploited to incorporate modifications ... -
Welding procedure qualification record (WPQR) for welds fabricated at proximity
(Peer reviewed; Journal article, 2022)Maintaining the minimum allowable distance between proximity welds has always been considered a subject of debate among design engineers, welding engineers/inspectors and fabricators/engineering contractors. The scattered ...
