Architecture of growth basins in a tidally influenced, prodelta to delta-front setting: The Triassic succession of Kvalpynten, East Svalbard
Smyrak-Sikora, Aleksandra; Osmundsen, Per Terje; Braathen, Alvar; Ogata, Kei; Anell, Ingrid Margareta; Mulrooney, Mark Joseph; Zuchuat, Valentin (Peer reviewed; Journal article, 2020)World‐class examples of fault‐controlled growth basins with associated syn‐kinematic sedimentary fill are developed in Upper Triassic prodelta to delta‐front deposits exposed at Kvalpynten, SW Edgeøya in East Svalbard. ... -
Architecture, deformation style and petrophysical properties of growth fault systems: the Late Triassic deltaic succession of southern Edgeøya (East Svalbard)
Ogata, Kei; Mulrooney, Mark; Braathen, Alvar; Maher, Harmon; Osmundsen, Per Terje; Anell, Ingrid Margareta; Smyrak-Sikora, Aleksandra; Balsamo, Fabrizio (Peer reviewed; Journal article, 2018-05-07)The Late Triassic outcrops on southern Edgeøya, East Svalbard, allow a multiscale study of syn‐sedimentary listric growth faults located in the prodelta region of a regional prograding system. At least three hierarchical ... -
Exploring seismic detection and resolution thresholds of fault zones and gas seeps in the shallow subsurface using seismic modelling
Faleide, Thea Sveva; Braathen, Alvar; Lecomte, Isabelle Christine; Anell, Ingrid (Journal article; Peer reviewed, 2022)Seismic resolution and illumination issues are sources of challenges in the detailed imaging and detection of subsurface fault architecture and fluid migration. Improved constraints on resolution can provide input into ... -
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 seismic resolution on fault interpretation: Insights from seismic modelling
Faleide, Thea Sveva; Braathen, Alvar; Lecomte, Isabelle Christine; Mulrooney, Mark Joseph; Midtkandal, Ivar; Bugge, Aina J.; Planke, Sverre (Journal article; Peer reviewed, 2021)Seismic mapping of subsurface faults is hampered by factors such as seismic resolution, velocity control for depth conversion and human bias. Here, we explore the challenges and pitfalls related to interpreting normal ... -
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 ... -
