Deep learning for graphs
(Chapter, 2018)Deep learning for graphs encompasses all those neural models endowed with multiple layers of computation operating on data represented as graphs. The most common building blocks of these models are graph encoding layers, ... -
Defining acoustic emission-based condition monitoring indicators for monitoring piston rod seal and bearing wear in hydraulic cylinders
(Peer reviewed; Journal article, 2021)Fluid leakage from hydraulic cylinders is a major concern for the offshore industries as it directly affects hydraulic cylinder energy efficiency and causes environmental contamination. There have been attempts made in ... -
Detecting and Interpreting Faults in Vulnerable Power Grids With Machine Learning
(Journal article; Peer reviewed, 2021)Unscheduled power disturbances cause severe consequences both for customers and grid operators. To defend against such events, it is necessary to identify the causes of interruptions in the power distribution network. In ... -
Detection of lameness and mastitis pathogens in milk using visual and olfactory sensing
(Research report, 2020)The objective of this project is to investigate feasibility of visual combined with olfactory sensing and multimodal collaborative intelligence for the perception of diseases, especially the contagious ones, among a ... -
Diagnostics of seal and rod degradation in hydraulic cylinders using acoustic emissions
(Peer reviewed; Journal article, 2020)External leakage from hydraulic cylinders is of a major concern for the offshore oil and gas industry. This occurs mainly as a result of physical damage to the piston rod or due to degradation of the piston rod seals. ... -
Differences in Direct Geothermal Energy Utilization for Heating and Cooling in Central and Northern European Countries
(Peer reviewed; Journal article, 2023)Geothermal energy has emerged as an alternative heating source that can replace fossil energy. This mature technology is already in use all over Europe, but there are significant differences in its use between European ... -

(ACT DigiMon (NORCE);D4.9, Research report, 2023)"DigiMon Final Report” summarizes the ACT DigiMon project. The overall objective of the DigiMon project was to “accelerate the implementation of CCS by developing and demonstrating an affordable, flexible, societally ... -
Digital Monitoring of Co2 Storage Projects (Digimon)
(Journal article, 2021)With an overall objective to “accelerate the implementation of CCS by developing and demonstrating an affordable, flexible, societally embedded and smart Digital Monitoring early-warning system”, the DigiMon project aims ... -
DigiTrans kortrapport: Studentenes opplevelse av studiesituasjonen under nedstengingene av UiB høsten 2020
(Research report, 2021)Universitetet i Bergen (UiB) måtte høsten 2020 igjen stenge tilgangen til «campus» for sine studenter for å hindre spredningen av koronaviruset på grunn av den pågående pandemisituasjonen. For de fleste studentene ble ... -
Dimensional reduction of a fractured medium for a polymer EOR model
(Peer reviewed; Journal article, 2021)Dimensional reduction strategy is an effective approach to derive reliable conceptual models to describe flow in fractured porous media. The fracture aperture is several orders of magnitude smaller than the characteristic ... -
Direct Multi-Modal Inversion of Geophysical Logs Using Deep Learning
(Peer reviewed; Journal article, 2022)Geosteering of wells requires fast interpretation of geophysical logs which is a non-unique inverse problem. Current work presents a proof-of-concept approach to multi-modal probabilistic inversion of logs using a single ... -
A Discrete-Domain Approach to Three-Phase Hysteresis in Porous Media
(Peer reviewed; Journal article, 2021)We present a discrete-domain approach to three-phase displacements and hysteresis in porous media. In this method, constrained energy minimization leads to evolution equations for local saturations that describe a wide ... -
Drilling Data Hub
(Research report, 2020)Deploying advanced automation solutions on a large scale is a current challenge. Experience shows that a considerable amount of work must be performed before every single use of those solutions: we refer here to the necessity ... -
Dynamic estimates of extreme-case CO2 storage capacity for basin-scale heterogeneous systems under geological uncertainty
(Peer reviewed; Journal article, 2022)Geological CO2 storage is expected to grow dramatically in the coming decades to meet global climate targets. Assessment of worldwide storage resources using static methods indicates significant theoretical potential for ... -
Dynamic PVT model for CO2-EOR black-oil simulations
(Peer reviewed; Journal article, 2022)A well-planned CO2EOR operation can help meet an ever-increasing need for energy and at the same time reduce the total CO2 footprint from the energy production. Good simulation studies are crucial for investment decisions ... -
Dynamic repositioning in floating wind farms
(Research report, 2020)The potential for harvesting Norwegian offshore wind power resourcesis undoubtably tremendous, however, currently limited by the cost of energy especially at deep waters. A general challenge for wind power production is ... -
Economic Evaluation of Eight Regional Scenarios for the Deployment of Carbon Capture, Use and Storage in Southern and Eastern Europe to 2050
