Creating Value From Brown Fields Through High-Quality Decision Making
(Masteroppgave/UIS-TN-IEP/2020;, Master thesis, 2020-06)Whether facing pandemics, negative oil prices or other crises, the key to value creation is to make good decisions. Decisions are always about the future and the one thing we know for sure about the future is that it is ... -
Criterion for sufficiently large dither amplitude to mitigate non-linear glitches
(Chapter, 2023)A model describing glitch disturbances is introduced and analysed. The model is used to find the response of glitch disturbances when adding a periodic dither to the input and applying low-pass filtering to the output. ... -
A critical review on production, modification and utilization of biochar
(Peer reviewed; Journal article, 2021)There has been an increased interest in the production of sustainable biochar in the past years, as biochar shows versatile physicochemical properties and, can have a wide applicability in diverse fields. Comprehensive ... -
A Critical Review on the Use of Shallow Geothermal Energy Systems for Heating and Cooling Purposes
(Peer reviewed; Journal article, 2022)The reduction of CO2 emissions has become a global concern. In this regard, the EU intends to cut CO2 emissions by 55% by 2030 compared to those of 1990. The utilization of shallow geothermal energy (SGE) in EU countries ... -
Cuttings transport with oil- and water-based drilling fluids
(Chapter, 2021)Deviated well sections are common in modern well construction. In mature areas like the North Sea region, practically all producers or injector wells will have highly deviated sections. These wells must be drilled and ... -
Dashboard for visualization, evaluation and modeling of wellbore and field H2S production
(Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-06)For several years, continuously increasing amounts of hydrogen sulfide (H2S) are being produced from numerous fields on the Norwegian Continental Shelf as a result of reservoir souring. Reservoir souring – increasing ... -
