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. ... -
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 ... -
Tectonostratigraphic development of the Upper Triassic to Middle Jurassic in the Hoop Area, Barents Sea: Implications for understanding ultra-condensed reservoir units
Müller, Reidar; Klausen, Tore Grane; Line, Lena; Hafeez, A; Planke, Sverre; Eide, Frøydis; Stueland, Erik; Jahren, Jens; Rismyhr, Bjarte; Olaussen, Snorre (Journal article; Peer reviewed, 2022)The most prolific reservoir intervals in the Barents Sea are found in the Upper Triassic to Middle Jurassic Realgrunnen Subgroup, deposited during a major change in the structural evolution of the basin which greatly ...
