Detrital zircons of the vast Triassic Snadd and De Geerdalen formations, Barents Shelf, reveal temporal changes in sediment source
(Peer reviewed; Journal article, 2023)Studies of detrital-zircon age distributions from Triassic sedimentary rock successions on the Arctic Barents Shelf have resulted in different provenance interpretations. Here, we provide new U–Pb/Hf detrital-zircon data ... -
Developing a procedure to sort and extract useful information from a mass production data
(Master thesis, 2012)Abstract The Rubiales field is a multi-well cluster field which creates severe amounts of production data. Rapid expansion has lead to massive increase in oil production. A consequence is missed opportunities of optimization ... -
Development and Assessment of a Multi-Pipe Oil-Water Bulk Separator Concept for Subsea Applications
(Doctoral theses at NTNU;2019:306, Doctoral thesis, 2019)Subsea produced water separation has emerged as a viable technology for tackling challenges arising from increased water production rates. Removing produced water at the seabed will free up topside capacity constrained ... -
Development of a 3D structural model of a mine by consolidating different data sources
(Journal article; Peer reviewed, 2017)Joints and faults are inherent parts of the rock mass. In the vast majority of mining slopes, discontinuity structures play an important role in slope stability and may trigger a slope failure. The most important step in ... -
Development of a new seabed coupled shear wave source:: VibroPile
(Doktoravhandlinger ved NTNU, 1503-8181; 2008:197, Doctoral thesis, 2008)This thesis describes the development of a new seismic shear wave source - VibroPile. The source has been developed to be installed on the sea oor. It can however also be used as an onshore shear wave generator, e.g. in ... -
Development of an automation method to conduct sensitivity analysis on weakness zones using Finite Element Modelling - with focus on total deformations
(Master thesis, 2022)I områder med harde bergarter, tilsvarende det Norske geologiske landskapet, er svakhetssoner en av de viktigste årsakene til stabilitetsrelaterte problemstillinger møtt i tunnelindustrien. Det er derfor nødvendig å få ... -
Development of an Ultraviolet-Spectrophotometric Method for Analysis of Esterquat-Containing Flotation Collectors in Aqueous Solutions
(Journal article; Peer reviewed, 2018)In this study, a rapid and simple ultraviolet‐spectrophotometric method was developed and validated for the quantitative determination of esterquat‐containing flotation collector FLOT 2015 in aqueous solutions. This method ... -
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 in-situ rock stress map of south-western part of Norway
(Chapter, 2024)Knowledge of in-situ rock stress is important for underground projects like mining, nuclear repository, hydropower and other utility tunnels and caverns for the assessment of stability condition. Specifically, it is very ... -
