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 ... -
Standards for the performance assessment of territorial landslide early warning systems
(Peer reviewed; Journal article, 2020)Landslide early warning systems (LEWS) can be categorized into two groups: territorial and local systems. Territorial landslide early warning systems (Te-LEWS) deal with the occurrence of several landslides in wide areas: ... -
Intact, Disturbed, and Reconstituted Undrained Shear Behavior of Low-Plasticity Natural Silt
(Peer reviewed; Journal article, 2020)This paper presents a laboratory investigation of undrained triaxial shear behavior of a natural low-plasticity silt from Halden, Norway in the intact, disturbed, and reconstituted states. Sherbrooke block sample and ... -
Caprock characterization of Upper Jurassic organic-rich shales using acoustic properties, Norwegian Continental Shelf
(Peer reviewed; Journal article, 2020)Our analysis of a comprehensive well log database and complementary mineralogical and geochemical information indicates that the risk for Upper Jurassic shales on the Norwegian Continental Shelf (NCS) to permit severe ... -
State-of-the-art review of soft computing applications in underground excavations
(Peer reviewed; Journal article, 2019)Soft computing techniques are becoming even more popular and particularly amenable to model the complex behaviors of most geotechnical engineering systems since they have demonstrated superior predictive capacity, compared ... -
Factual report - Øysand research site
(NGI-rapport;20160154-08-R, Report, 2020-01-15)As part of the characterization of Øysand Sand site during NGTS project, two main reports are prepared: 1) a factual report (20160154-08-R) and 2) an interpretation report (20160154-09-R) (see figure in the next page). The ... -
Factual Report - Permafrost Research Site
(NGI-rapport;20160154-06-R, Report, 2020-01-01)Two benchmark sites are established near Longyearbyen, Svalbard (78°13’N, 15°28’E) for long-term geotechnical testing and evaluation of field investigation methods in perennially frozen soils (i.e. permafrost). These sites, ... -
Project Execution Manual
(NGI-rapport; 20160154-01-R Rev. 3, Report, 2017-08-23)This project execution manual should be used as a basis for all work performed as part of the Norwegian Geo-Test Sites project (NGTS). The project is based on the reviewed proposal submitted to The Research Council of ... -
Evaluation and Monitoring of Slope Stability in Cold Region: Case Study of Man-Made Slope at Øysand, Norway
(Peer reviewed; Journal article, 2020)Recently, the road and railways infrastructure developments in Norway have led to renewed interests on the geotechnical challenges associated with slope stability under freezing-thawing cycles. Despite the amount of research ... -
Algorithms for intelligent prediction of landslide displacements
(Peer reviewed; Journal article, 2020)Landslides represent major threats to life and property in many areas of the world, such as the landslides in the Three Gorges Dam area in mainland China. To better prepare for landslides in this area, we explored how ... -
Earthquake response of monopiles and caissons for Offshore Wind Turbines founded in liquefiable soil
(Peer reviewed; Journal article, 2020)Monopile has been the most widespread foundation type for Offshore Wind Turbines (OWTs) in shallow waters. Caisson (skirted) foundations have also been evaluated in some projects as an economical alternative. While the ... -
The correlation between pO2 and pCO2 as a chemical marker for detection of offshore CO2 leakage
(Peer reviewed; Journal article, 2020)A controlled CO2 release experiment was carried out in order to mimic unintended leakage of geologically stored CO2, and to study methods for detecting these leak events. The experiment was carried out at 60 m depth in the ... -
Compaction, rock physics and rock properties of sandstones of the Stø Formation: Case study of five wells from the south-western Barents Sea, Norway
(Peer reviewed; Journal article, 2020)Five wells containing Lower-Middle Jurassic sandstones of Stø Formation from the Hammerfest Basin (7120/9–1, 7121/7–1), the Ringvassøy-Loppa Fault Complex (7119/12–1, 7119/12–4) and the Troms-Finnmark Fault Complex (7019/1-1) ... -
On the landslide tsunami uncertainty and hazard
(Peer reviewed; Journal article, 2020)Landslides are the second most frequent tsunami source worldwide. However, their complex and diverse nature of origin combined with their infrequent event records make prognostic modelling challenging. In this paper, we ... -
Throw variations and strain partitioning associated with fault-bend folding along normal faults
