Changing provenance and stratigraphic signatures across the Triassic–Jurassic boundary in eastern Spitsbergen and the subsurface Barents Sea
Klausen, Tore Grane; Rismyhr, Bjarte; Müller, Reidar; Olaussen, Snorre (Journal article; Peer reviewed, 2022)A change to more sandstone dominated deposits and increasing condensation across the Triassic–Jurassic boundary is generally associated with improved reservoir quality in the Barents Sea. However, spatial and temporal ... -
Facies, palynostratigraphy and sequence stratigraphy of the Wilhelmøya Subgroup (Upper Triassic–Middle Jurassic) in western central Spitsbergen, Svalbard
Rismyhr, Bjarte; Bjærke, Tor; Olaussen, Snorre; Mulrooney, Mark Joseph; Senger, Kim (Peer reviewed; Journal article, 2019)The Wilhelmøya Subgroup (Norian–Bathonian) is considered as the prime storage unit for locally produced CO2 in Longyearbyen on the Arctic archipelago of Svalbard. We here present new drillcore and outcrop data and refined ... -
Fluid flow properties of the Wilhelmøya Subgroup,a potential unconventional CO2 storage unit in central Spitsbergen
Mulrooney, Mark Joseph; Larsen, Leif; Van Stappen, Jeroen; Rismyhr, Bjarte; Senger, Kim; Braathen, Alvar; Olaussen, Snorre; Mørk, Mai Britt Engeness; Ogata, Kei; Cnudde, Veerle (Peer reviewed; Journal article, 2019)The Upper Triassic to Middle Jurassic Wilhelmøya Subgroup forms one of the more suitable reservoir units on the Norwegian Arctic archipelago of Svalbard. The target siliciclastic storage unit, which is encountered at approx. ... -
Fluid migration pathways to seafloor seepage in inner Isfjorden and Adventfjorden, Svalbard
Roy, Srikumar; Senger, Kim; Braathen, Alvar; Noormets, Riko; Hovland, Martin; Olaussen, Snorre (Peer reviewed; Journal article, 2014)This study represents a marine baseline study for the Longyearbyen CO2 Lab, in which CO2 may be injected in the Upper Triassic–Middle Jurassic Kapp Toscana Group, which comprises several permeable beds. The target ... -
Geometries of doleritic intrusions in central Spitsbergen, Svalbard: an integrated study of an onshore-offshore magmatic province with implications for CO2 sequestration
Senger, Kim; Roy, Srikumar; Braathen, Alvar; Buckley, Simon John; Bælum, Karoline; Gernigon, Laurent; Mjelde, Rolf; Noormets, Riko; Ogata, Kei; Olaussen, Snorre; Planke, Sverre; Ruud, Bent Ole; Tveranger, Jan (Peer reviewed; Journal article, 2013)Igneous intrusions emplaced during the Early Cretaceous are well exposed in central Spitsbergen within the Permian–Jurassic sedimentary succession. The doleritic intrusions are collectively classified as the Diabasodden ... -
Impacts of small-scale faults on continental to coastal plain deposition: Evidence from the Realgrunnen Subgroup in the Goliat field, southwest Barents Sea, Norway
Mulrooney, Mark; Rismyhr, Bjarte; Yenwongfai, Honore Dzekamelive; Leutscher, Johan; Olaussen, Snorre; Braathen, Alvar (Peer reviewed; Journal article, 2018-08)In this study we synthesise sedimentological, fault, and Amplitude Versus Angle (AVA) analysis and propose that the Fruholmen and Tubåen formations (Realgrunnen Subgroup) are syn-kinematic deposits that record a previously ... -
Linking regional unconformities in the Barents Sea to compression-induced forebulge uplift at the Triassic-Jurassic transition
Müller, Reidar; Klausen, Tore Grane; Faleide, Jan Inge; Olaussen, Snorre; Eide, Christian Haug; Suslova, Anna A.; Suslova, Elena N. (Peer reviewed; Journal article, 2019)The Triassic-Jurassic transition marks an important change in the basin configuration of the Greater Barents Sea. A contiguous basin with km-thick sedimentary successions changed into a partitioned basin with uplift in the ... -
Petroleum, coal and research drilling onshore Svalbard: a historical perspective
Senger, Kim; Brugmans, Peter; Grundvåg, Sten-Andreas; Jochmann, Malte Michel; Nøttvedt, Arvid; Olaussen, Snorre; Skotte, Asbjørn; Smyrak-Sikora, Aleksandra (Peer reviewed; Journal article, 2019)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, ... -
Quartz overgrowth textures and fluid inclusion thermometry evidence for basin-scale sedimentary recycling: An example from the Mesozoic Barents Sea Basin
Haile, Beyene Girma; Line, Lina Hedvig; Klausen, Tore Grane; Olaussen, Snorre; Eide, Christian Haug; Jahren, Jens; Hellevang, Helge (Journal article; Peer reviewed, 2020)Sedimentary recycling has the potential to obscure source-to-sink relationships, provenance interpretations, burial history reconstructions and robust reservoir quality predictions in siliciclastic sedimentary basins. Here, ... -
Sedimentology and palynology of the Lower Cretaceous succession of central Spitsbergen: integration of subsurface and outcrop data
Grundvåg, Sten-Andreas; Jelby, Mads Engholm; Śliwińska, Kasia Kamila; Nøhr-Hansen, Henrik; Aadland, Tore; Sandvik, Sara Elvelund; Tennvassås, Ingrid; Engen, Thea Marie; Olaussen, Snorre (Peer reviewed; Journal article, 2019-06-27)The Lower Cretaceous succession in Svalbard is commonly considered as an important analogue to age-equivalent strata on the Barents Shelf which are sporadically targeted by exploration wells. In this study, the stratigraphic ... -
