CO2 Convection in Hydrocarbon Under Flowing Conditions
(Peer reviewed; Journal article, 2021)Carbon-neutral oil production is one way to improve the sustainability of petroleum resources. The emissions from produced hydrocarbons can be offset by injecting capture CO2 from a nearby point source into a saline aquifer ... -
CO2 Convective Dissolution in Oil-Saturated Unconsolidated Porous Media at Reservoir Conditions
(Peer reviewed; Journal article, 2021)During CO2 storage, CO2 plume mixes with the water and oil present at the reservoir, initiated by diffusion followed by a density gradient that leads to a convective flow. Studies are available where CO2 convective mixing ... -
CO2 Dissolution and Convection in Oil at Realistic Reservoir Conditions: A Visualization Study.
(Peer reviewed; Journal article, 2021)CO2 convective mixing has been extensively studied for CO2 dissolution in saline water but very limited with the presence of oil. The objective of this work was to visually study the supercritical CO2 (sCO2) dissolution ... -
A combined finite element–finite volume framework for phase-field fracture
(Peer reviewed; Journal article, 2021)Numerical simulations of brittle fracture using phase-field approaches often employ a discrete approximation framework that applies the same order of interpolation for the displacement and phase-field variables. In particular, ... -
Combined Thickness and Permittivity Measurement of Thin Layers with Open-Ended Coaxial Probes
(Peer reviewed; Journal article, 2019)This paper presents a method to simultaneously determine the thickness and permittivity of thin layers from multi-frequency reflection coefficient measurements using an open-ended coaxial probe. This is achieved by exploiting ... -
Combined Use of Aerial Photogrammetry and Terrestrial Laser Scanning for Detecting Geomorphological Changes in Hornsund, Svalbard
(Peer reviewed; Journal article, 2022)The Arctic is a region undergoing continuous and significant changes in land relief due to different glaciological, geomorphological and hydrogeological processes. To study those phenomena, digital elevation models (DEMs) ... -
Combining direct and indirect sparse data for learning generalizable turbulence models
(Peer reviewed; Journal article, 2023)Learning turbulence models from observation data is of significant interest in discovering a unified model for a broad range of practical flow applications. Either the direct observation of Reynolds stress or the indirect ... -
Comprehensive Direct Georeferencing of Aerial Images for Unmanned Aerial Systems Applications
(Peer reviewed; Journal article, 2022)Optical image sensors are the most common remote sensing data acquisition devices present in Unmanned Aerial Systems (UAS). In this context, assigning a location in a geographic frame of reference to the acquired image is ... -
Computer Vision Based Path Following for Autonomous Unammed Aerial Systems in Unburied Pipeline Onshore Inspection
(Peer reviewed; Journal article, 2022)Unmanned Aerial Systems (UAS) are becoming more attractive in diverse applications due to their efficiency in performing tasks with a reduced time execution, covering a larger area, and lowering human risks at harmful ... -
Concept description for the use of fibre-optic measurements for seismic tomography
(ACT DigiMon (NORCE);D2.2, Research report, 2021)High resolution mapping of CO2 plumes in the geological storage formations can be obtained using cross well seismic experiments designed to characterise velocity changes in the subsurface, see figure 1. High resolution ... -
Condition monitoring and maintenance for fibre rope moorings in offshore wind
(Research report, 2023)The FIRM project aims to develop innovative mooring systems for floating wind farms based on fibre ropes, including new and more efficient methods for installation, condition monitoring, maintenance, and decommissioning. ... -
Condition monitoring of hydraulic cylinder seals using acoustic emissions
(Peer reviewed; Journal article, 2020)In recent years, there has been a growing concern for fluid spill from hydraulic cylinders in the offshore oil and gas industry. To diagnose the leakage from hydraulic cylinders, there have been attempts made in literature ... -
Connecting Multilayer Semantic Networks to Data Lakes: The Representation of Data Uncertainty and Quality
(Peer reviewed; Journal article, 2022)Drilling oil and gas wells is a complex process involving many disciplines and stakeholders. This process occurs in a context where some pieces of information are unknown, or are often incomplete, erroneous, or at least ... -
Consistent ice and open water classification combining historical synthetic aperture radar satellite images from ERS-1/2, Envisat ASAR, RADARSAT-2 and Sentinel-1A/B
(Peer reviewed; Journal article, 2019)Synthetic Aperture Radar (SAR) satellite images are used to monitor Arctic sea ice, with systematic data records dating back to 1991. We propose a semi-supervised classification method that separates open water from sea ... -
Controlled Interactivity - lean-back media experiences based on lean-forward technologies
(Lecture, 2023)Interactive rendering technologies like maps, timelines, and plots can be powerful tools for data visualization and exploration. In the context of media, such tools are often referred to as lean-forward, implying that the ... -
Convective Mixing Driven by Non-monotonic Density
(Peer reviewed; Journal article, 2021)CO2 injection for enhanced oil recovery (CO2-EOR) or for storage in depleted oil and gas reservoirs can be a means for disposing of anthropogenic CO2 emissions to mitigate climate change. Fluid flow and mixing of CO2 and ... -
