Experimental investigation of natural fracture stiffness and flow properties in a faulted CO2 bypass system (Utah, USA)
(Peer reviewed; Journal article, 2020)Fracture stiffness and flow properties have been measured in the laboratory using naturally fractured fault rock samples from the Little Grand Wash fault, Utah, USA. We compare fracture closure and related flow change ... -
Interaction of deformation bands and fractures during progressive strain in monocline - San Rafael Swell, Central Utah, USA
(Peer reviewed; Journal article, 2020) -
Facilitating microplastic quantification through the introduction of a cellulose dissolution step prior to oxidation: Proof-of-concept and demonstration using diverse samples from the Inner Oslofjord, Norway
(Peer reviewed; Journal article, 2020)Identifying and quantifying microplastic in marine samples can be facilitated by removing natural organic matter (NOM). Cellulosic material, like chitin, however, are a type of NOM that is resistant to chemical digestion, ... -
Seismic-fluid detection-a review
(Peer reviewed; Journal article, 2020) -
Effect of kinematic interaction on seismic response of offshore wind turbines on monopiles
(Peer reviewed; Journal article, 2020)Interest in renewable energy over the past decade has motivated a remarkable research on offshore wind energy. Due to the environmental loading conditions in the early developments of offshore wind farms, the focus of the ... -
Effects of acidic water on hydro-mechanical properties of asphalt concrete
(Peer reviewed; Journal article, 2020)Asphalt concrete is widely used in road and airport pavements and more recently also in the construction of impervious facings and central cores in dams and dykes. Asphalt concrete may be subjected to strongly acidic water ... -
Fluorinated Precursor Compounds in Sediments as a Source of Perfluorinated Alkyl Acids (PFAA) to Biota
(Peer reviewed; Journal article, 2020)The environmental behavior of perfluorinated alkyl acids (PFAA) and their precursors was investigated in lake Tyrifjorden, downstream a factory producing paper products coated with per- and polyfluorinated alkyl substances ... -
Wetting-induced collapse behaviour of a natural and vegetated coarse pyroclastic soil
(Peer reviewed; Journal article, 2020)Unsaturated pyroclastic soils originated by Vesuvius volcano show a collapsible behaviour upon wetting with a significant reduction in volume and rearrangement of solid skeleton. The paper investigates the role played by ... -
Design and performance of the Quxue asphalt-core rockfill dam
(Peer reviewed; Journal article, 2020)The design and performance of the 174-m high Quxue asphalt-core rockfill dam in Sichuan Province, China, are presented. An extensive field monitoring program was implemented. During construction, the asphalt core settled ... -
A Novel Small-Scale Model Testing Device for Laterally Loaded Piles
(Chapter, 2020) -
Design considerations of suction caisson foundations for offshore wind turbines in Southern China
(Peer reviewed; Journal article, 2020)Suction caisson foundations are increasingly considered as a foundation solution for offshore wind farm development in China. This paper outlines the design considerations for developing a suction caisson supported jacket ... -
Geophysical early warning of salt precipitation during geological carbon sequestration
(Peer reviewed; Journal article, 2020)Sequestration of industrial carbon dioxide ( CO 2) in deep geological saline aquifers is needed to mitigate global greenhouse gas emissions; monitoring the mechanical integrity of reservoir formations is essential for ... -
Considerations on scaling behavior in avalanche flow: Implementation in a simple mass block model
(Peer reviewed; Journal article, 2020)Observations of runout distances combined with velocity measurements suggest that “major” dry-mixed avalanches show a scale invariance to the total drop height HSC. This is in accordance to the proposed upper-limit envelope ... -
A Benchmark Case Study for Seismic Event Relative Location
(Peer reviewed; Journal article, 2020)“Precision seismology” encompasses a set of methods which use differential measurements of time-delays to estimate the relative locations of earthquakes and explosions. Delay-times estimated from signal correlations often ... -
Layering in shales controls microfracturing at the onset of primary migration in source rocks
(Peer reviewed; Journal article, 2020)The process of primary migration, which controls the transfer of hydrocarbons from source to reservoir rocks, necessitates the existence of fluid pathways in low permeability sedimentary formations. Primary migration starts ... -
A procedure for predicting the permanent rotation of monopiles in sand supporting offshore wind turbines
(Peer reviewed; Journal article, 2020)Foundations for Offshore Wind Turbines (OWTs) are designed following the limit state philosophy. One of the considered states is the Serviceability Limit State (SLS), which verifies that the permanent rotation of the ... -
Organic-rich shale caprock properties of potential CO2 storage sites in the northern North Sea, offshore Norway
(Peer reviewed; Journal article, 2020)Assessment of the geomechanical properties of organic-rich shale caprocks is critical for a successful CO2 storage into a saline aquifer. In this study, we investigated the geochemical properties of the organic-rich shale ... -
Microplastic accumulation by tube-dwelling, suspension feeding polychaetes from the sediment surface: A case study from the Norwegian Continental Shelf
(Peer reviewed; Journal article, 2020)Sediment samples (0–1 cm) and tube-dwelling polychaetes from the Norwegian Continental Shelf and the Barents Sea were collected, including areas close to oil and gas installations and remote locations. Microplastics (≥45 μm) ... -
Building damage due to vibration from rock blasting
(Peer reviewed; Journal article, 2020)Construction activities such as blasting, piling, compaction, excavations, and construction traffic can produce vibrations of sufficient strength to cause damage to neighbouring buildings and structures. Therefore, many ...
