Cenozoic uplift and erosion of the Norwegian Barents Shelf – A review
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-03-23)Uplift and erosion are complex phenomena in terms of their governing processes, precise timing and exact magnitude. The intricate relationship between different geodynamic processes leading to uplift may increase uncertainties in estimating spatial and temporal patterns. Sediment distribution from uplifted (and eroded) topography and the corresponding paleoenvironmental reconstructions require ... -
Deep-time Arctic climate archives: high-resolution coring of Svalbard's sedimentary record – SVALCLIME, a workshop report
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-10-26)We held the MagellanPlus workshop SVALCLIME “Deep-time Arctic climate archives: high-resolution coring of Svalbard's sedimentary record”, from 18 to 21 October 2022 in Longyearbyen, to discuss scientific drilling of the unique high-resolution climate archives of Neoproterozoic to Paleogene age present in the sedimentary record of Svalbard. Svalbard is globally unique in that it facilitates ... -
Digitising Svalbard’s geology: the Festningen digital outcrop model
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-03-10)The renowned Festningen section in the outer part of Isfjorden, western Spitsbergen, offers a c. 7 km-long nearly continuous stratigraphic section of Lower Carboniferous to Cenozoic strata, spanning nearly 300 million years of geological history. Tectonic deformation associated with the Paleogene West-Spitsbergen-Fold-and-Thrust belt tilted the strata to near-vertical, allowing easy access to the ... -
First-order estimation of in-place natural gas resources at the Nyegga gas hydrate prospect, mid-Norwegian Margin
(Master thesis; Mastergradsoppgave, 2009-12-07)Gas hydrates are solid compounds of a guest gas molecule (primarily methane) enclosed in a lattice of host water molecules, occurring under specific pressure-temperature conditions in both natural and manmade environments. In the past decade, gas hydrates are increasingly investigated as a potential new energy source. This thesis presents an integrated evaluation of the gas bound within the hydrate ... -
Fracture characterization in Upper Permian carbonates in Spitsbergen: A workflow from digital outcrop to geo-model
(Journal article; Tidsskriftartikkel, 2020-09-08)Carbonates represent major hydrocarbon reservoirs, but often exhibit highly heterogeneous reservoir properties. Outcrop analogues provide important insights into how parameters such as porosity, permeability and natural fractures vary. As such, outcrops can bridge the scale gap between spatially extensive but poor-resolution seismic data and 1D high-resolution well data. However, traditional geological ... -
Hydrate occurrence in Europe: A review of available evidence
(Journal article; Tidsskriftartikkel, 2019-08-16)Large national programs in the United States and several Asian countries have defined and characterised their marine methane hydrate occurrences in some detail, but European hydrate occurrence has received less attention. The European Union-funded project “Marine gas hydrate – an indigenous resource of natural gas for Europe” (MIGRATE) aimed to determine the European potential inventory of exploitable ... -
Petroleum, coal and research drilling onshore Svalbard: a historical perspective
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-07-05)The beginning of the Norwegian oil industry is often attributed to the first exploration drilling in the North Sea in 1966, the first discovery in 1967 and the discovery of the supergiant Ekofisk field in 1969. However, petroleum exploration already started onshore Svalbard in 1960 with three mapping groups from Caltex and exploration efforts by the Dutch company Bataaffse (Shell) and the Norwegian ... -
Resistivity of reservoir sandstones and organic rich shales on the Barents Shelf: Implications for interpreting CSEM data
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-09-03)Marine controlled source electromagnetic (CSEM) data have been utilized in the past decade during petroleum exploration of the Barents Shelf, particularly for de-risking the highly porous sandstone reservoirs of the Upper Triassic to Middle Jurassic Realgrunnen Subgroup. In this contribution we compare the resistivity response from CSEM data to resistivity from wireline logs in both water- and ... -
Seal characterization and integrity in uplifted basins: Insights from the northern Barents Shelf
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-02-16)Seal integrity is a key property for petroleum exploration. This is even more the case in uplifted basins, as exemplified by the northern Barents Shelf. Uplift may lead to fracturing, decompaction, gas expansion and fluid flow. Therefore, it is critical to understand the mechanical behaviour of the Jurassic shale caprocks in the Greater Hoop area, where hydrocarbon accumulations are situated as ... -
Seal integrity in the uplifted basins in the greater Hoop area on the Northern Barents Shelf
(Conference object; Konferansebidrag, 2019)The geological evolution of the northern Barents Shelf is complex, and the area has undergone several phases of tectonic activity leading to a mosaic of several deep and shallow basins, platforms, salt-cored domes and structural highs. The area is highly gas prone with some very few commercial oil discoveries, and only two fields currently in production. Deep burial and subsequent Late Cretaceous–Cenozoic ... -
Seeing beyond the outcrop: Integration of ground-penetrating radar with digital outcrop models of a paleokarst system
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-11-25)Paleokarst breccias are a common feature of sedimentary rift basins. The Billefjorden Trough in the High Arctic archipelago of Svalbard is an example of such a rift. Here the Carboniferous stratigraphy exhibits intervals of paleokarst breccias formed by gypsum dissolution. In this study we integrate digital outcrop models (DOMs) with a 2D ground penetrating radar (GPR) survey to extrapolate external ... -
The Svalbard Carboniferous to Cenozoic Composite Tectono-Stratigraphic Element
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-08-26)The Svalbard Composite Tectono-Stratigraphic Element is located on the north-western corner of the Barents Shelf and comprises a Carboniferous to Pleistocene sedimentary succession. Due to Cenozoic uplift the succession is subaerially exposed in the Svalbard archipelago. The oldest parts of the succession consist of Carboniferous to Permian mixed siliciclastic, carbonate and evaporite and spiculitic ... -
Svalbard Composite Tectono-Sedimentary Element, Barents Sea
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-03-06)The Svalbard Composite Tectono-Sedimentary Element (SCTSE) is located on the northwestern corner of the Barents Shelf and comprises a Carboniferous–Pleistocene sedimentary succession. Due to Cenozoic uplift, the succession is subaerially exposed in the Svalbard archipelago. The oldest parts of the succession consist of Carboniferous–Permian mixed siliciclastic, carbonate and evaporite, and spiculitic ... -
Teaching with digital geology in the high Arctic: opportunities and challenges
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-09-28)<p>The Covid-19 pandemic occurred at a time of major revolution in the geosciences – the era of digital geology. Digital outcrop models (DOMs) acquired from consumer drones, processed using user-friendly photogrammetric software and shared with the wider audience through online platforms are a cornerstone of this digital geological revolution. Integration of DOMs with other geoscientific data, such ... -
You learn as long as you drill; research synthesis from the Longyearbyen CO2 Laboratory, Svalbard, Norway
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-01-21)From 2007 to 2015, eight wells were drilled and fully cored to test the feasibility of storing CO<sub>2</sub> emitted from the coal-fueled power plant in Longyearbyen, Svalbard. The drilling campaign identified three water-bearing sandstone aquifers; i) a lower aquifer in Upper Triassic strata; ii) a middle aquifer in Upper Triassic to Middle Jurassic; and iii) an upper aquifer in Lower Cretaceous ...
