...subsurface and of demonstrating that the CO₂ is safely stored in the reservoir (Xue and Ohsumi, 2004). In this work, the effect of CO₂ on P- and S-wave velocities was investigated. Laboratory measurements were performed with Castlegate sandstone both at seismic frequencies (1–155 Hz), and at ultrasonic...

Authorities (PSA) emphasis on major accidents and barrier management, where maintenance and maintenance management play important parts. Previous studies and the PSA's own supervision have revealed weaknesses and potential for improvement in both barrier management and maintenance management. The PSA therefore...

...produced water and oil droplets. The PWC-Arctic project endeavors to assess the potential environmental impact of oil exploration in the High North by quantifying the uptake and excretion kinetics of selected produced water components and oil droplets and their effects on growth, development and reproduction...

Selv ved elfiske på lave vannføringer har ungfisktettheten ofte vært lav. Den mest nærliggende faktoren til å forklare den dårlige utviklingen i ungfiskbestanden er dårlig vannkvalitet, men tap av fisk ved stranding under raske nedtappinger av vannmengden gjennom kraftverket kan ikke utelukkes. På strekningen...

...extensive use of ICT in the power system, enabling increased flexibility and functionality and thereby meeting future demands and strategic goals. Consequently, power system reliability will increasingly depend on ICT components and systems. While adding functionality, ICT systems also contribute to failures...

The purpose of this study was to evaluate the stability and therefore suitability of available fifth generation (5G) and long-term evolution (LTE) signals for positioning navigation and timing (PNT) purposes with particular focus on answering questions around the time-scale-dependent stability of these...

Developing cost-efficient systems for transporting CO₂ is key to accelerate the deployment of carbon capture and storage. The present work explores the impact of reducing the pressure of tank-based inland and at-sea transport on their techno-economic performance. The study uses established techno-economic models...

...vulnerabilities and more. We agree with Gibson-Graham (2006) that the core of the issue for a post-capitalist politics is to overcome the sense of the inevitability of the dominant system of political economy. With this argument in mind, we analyse the diversity, innovativeness, and resilience of two...
