Development of Bio-Oil Emulsion to Allow Realistic Testing of Oil Spill Control Equipment
(Master thesis, 2015)Accidental release of oil to the sea poses may have dire ecological consequences and serious economic ramifications, as recent events have shown. Spill control equipment as: booms, skimmers and oil trawls may protect ... -
Development of bismuth-based solutions for well plugging and abandonment: A review
(Journal article; Peer reviewed, 2024)Plugging and abandonment (P&A) is a crucial step of the well life cycle. Regardless of how long one stretches the productive life of a well, P&A operations will have to be carried out eventually. The current panorama of ... -
Development of dynamic safety envelopes for autonomous remotely operated underwater vehicles
(Chapter, 2018)This paper describes the implementation of dynamic safety envelopes for Autonomous Remotely Operated Vehicles (AROVs). A safety envelope is defined as a three-dimensional spatial area around the AROV, which forms a virtual ... -
Development of ECO-UHPC utilizing gold mine tailings as quartz sand alternative
(Peer reviewed; Journal article, 2021)To ensure ultra-high performance, in terms strength and durability, coarse aggregate is typically avoided in UHPC (ultra-high performance concrete). Instead, very fine quartz sand is usually used as the only aggregate. ... -
Development Of Efficient Constraint-Handling Approaches For Well Placement Optimization
(Chapter, 2018)Efficient constraint-handling methodology is developed to solve for a set of concurrent geometric well placement constraints. This implementation enhances constraint-handling capability such that expert knowledge may more ... -

Development of process mineralogy for optimization and increased value of the mineral production in Sibelco Nordic
(Doktoravhandlinger ved NTNU, 1503-8181; 2013:228, Doctoral thesis, 2013)Process mineralogy is a term well known to the mining industry considering high income products like precious minerals and metals, but for lower income products like industrial minerals the term is not so familiar or ... -
Development of safety envelopes and subsea traffic rules for autonomous remotely operated vehicles
(Journal article; Peer reviewed, 2019)This article presents the process used to develop safety envelopes and subsea traffic rules for autonomous remotely operated vehicles (AROVs) used in subsea inspection, maintenance, and repair (IMR) operations. Preventing ... -
Development Towards a New Test Procedure for Flotation at Brønnøy Kalk
(Master thesis, 2016)Brønnøy Kalk AS is a mining company established in 1997 and is localized in Brønnøy, Norway. Approximately 2 million tonnes of ground calcium carbonate (GCC) raw material is mined annually. No processing of the marble is ... -
Diagenesis and Reservoir Properties of Sandstones of the Battfjellet and Aspelintoppen formations from Nordenskiöldfjellet, Svalbard.
(Master thesis, 2018)The Battfjellet and Aspelintoppen formations have been studied with the aim of finding textural and mineralogical properties of the sandstones and relate them to diagenesis processes and reservoir properties. The study was ... -
Diagenesis and reservoir quality of deep marine Upper Cretaceous sandstone; Nise formation in Vøring basin, offshore Mid-Norway.
(Master thesis, 2019)The present study deals with diagenesis and reservoir quality of deep marine (> 1.2 km water depth) Upper Cretaceous sandstones in Vøring Basin. Mineralogical and petrographical analysis has been done on the cored interval ... -
Diagenesis and Reservoir Quality of Sandstones from Offshore Kipatimu Formation of Songo Songo Gas Field with Comparison to the Onshore Kipatimu, Mitole and Nalwehe Formations of Mandawa Basin
(Master thesis, 2015)The potential of a sandstone to serve as a reservoir for producible hydrocarbons is closely related to its diagenetic history, which in turn is dependent upon its composition. The Mandawa Basin is probably the most prospective ... -
Diagenesis and Reservoir Quality of the Hugin Formation Sandstones in the North Sea: A Petrographical Approach
(Master thesis, 2013)The Middle Jurassic Hugin Formation in the Sleipner area has been studied in five wells in the southern Viking Graben in the Norwegian sector of the North Sea. The main objective is to understand how the diagenetic development ... -
Diagenesis and reservoir quality preserving mechanism in the deeply buried Lower to Middle Jurassic Formation in the Halten Terrace, offshore Mid-Norway.
(Master thesis, 2022)Heterolittiske sandsteinsreservoar fra Haltenterrassen har blitt undersøkt for å se på innvirkningen av diagenese på reservoarkvaliteten. For dette studiet har det blitt brukt 27 polerte tynnslip med blå epoxy farging fra ... -
Diagnosing Root Causes and Generating Graphical Explanations by Integrating Temporal Causal Reasoning and CBR
(Journal article; Peer reviewed, 2017)This study proposes a methodology to diagnose the root causes of failures in the domain of oil well drilling. The idea is to combine a Bayesian network, which is generated based on an expert knowledge, with situation-specific ... -
