Light transport in turbid water for 3D underwater imaging Open
In this work, we have investigated the properties of light transport in turbid water for underwater 3D imaging, by comparing literature, simulations, and experiments. The work is motivated by a need for high-quality 3D image data for under…
Monitoring casing corrosion of legacy wells using CSEM: Implications for large-scale energy and CO2 storage projects in shut-down hydrocarbon fields Open
Large-scale CO2 and energy storage is a mandatory part of the green shift to reduce CO2 emissions and limit consequences of climate change. Large-scale storage will require the use of shut-down depleted hydrocarbon fields to take advantage…
Screening, Monitoring, and Remediation of Legacy Wells to Improve Reservoir Integrity for Large-Scale CO2 Storage—An Example From the Smeaheia Structure in the Northern North Sea Open
Carbon capture and storage (CCS) is an inevitable action to achieve CO 2 emission reduction targets including becoming net-zero by 2050. Increased efforts are therefore required to identify suitable locations for large-scale CO 2 storage. …
Scattering-induced amplification of two-dimensional plasmons: Electromagnetic modeling Open
Using two rigorous electromagnetic approaches, we study plasmon scattering in two-dimensional systems and show that plasmon amplification is possible in the presence of dc currents. Two scenarios are considered: plasmon scattering from an …
Terahertz magnetoplasmon resonances in coupled cavities formed in a gated two-dimensional electron gas Open
We report on both experiments and theory of low-terahertz frequency range (up to 400 GHz) magnetoplasmons in a gated two-dimensional electron gas at low (<4K) temperatures. The evolution of magnetoplasmon resonances was observed as a funct…
Evaluating the well integrity of old exploration wells as a risk factor for future storage projects – an example from the Troll field in the Norwegian North Sea Open
More than 750 wildcat wells have been drilled in the Norwegian North Sea since 1966. Some of these wells could pose a risk for the environment, climate, and future H2 and CO2 storage projects by being preferred leakage paths for subsurface…
From Pre-Screening to Monitoring of Plugged and Abandoned Marine Exploration Wells - Enabling Reuse of Reservoirs for Co2 Storage through Geophysical Monitoring Open
Decommissioning of platforms and permanent plugging and abandonment (P&A) of oil and gas wells is a major future financial challenge for oil producing countries. This is especially true for offshore wells in deep water, where heavyduty dri…
Artificial Intelligence for Well Integrity Monitoring Based on EM Data Open
Monitoring of integrity of plugged and abandoned (P&A'ed) wells is of interest for the oil and gas industry and for CO2 storage. The purpose of this study is to develop artificial intelligence (AI)-based approaches to detect anomalies or d…
Remote Magnetic Nanoparticle Manipulation Enables the Dynamic Patterning of Cardiac Tissues Open
The ability to manipulate cellular organization within soft materials has important potential in biomedicine and regenerative medicine; however, it often requires complex fabrication procedures. Here, a simple, cost‐effective, and one‐step…

Junctions between two-dimensional plasmonic waveguides in the presence of retardation Open
Plasmons in two-dimensional waveguides are traditionally analysed within the electrostatic approximation, which assumes that the plasmon phase velocity is much smaller than the velocity of light. However, novel effects have recently been d…
Terahertz Plasmon Resonances in Two-Dimensional Electron Systems: Modeling Approaches Open
Known approaches to modeling terahertz plasmons in two-dimensional electron sys-tems may differ significantly in their assumptions. There has, however, been littleeffort to analyze the differences between and application of different model…
