Ogata, Kei; Mulrooney, Mark; Braathen, Alvar; Maher, Harmon; Osmundsen, Per Terje; Anell, Ingrid Margareta; Smyrak-Sikora, Aleksandra; Balsamo, Fabrizio (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)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 ...

Maher, Harmon; Ogata, Kei; Braathen, Alvar (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)Cone-in-cone (CIC) and beef (BF) carbonate lenses ornament detachment zone faults underlying Triassic growth basins on Edgeøya. Field relationships place CIC and BF growth as during early diagenesis and a transition from ...

Betlem, Peter; Birchall, Thomas; Ogata, Kei; Park, Joonsang; Skurtveit, Elin; Senger, Kim (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Structure-from-motion (SfM) photogrammetry enables the cost-effective digital characterisation of seismic- to sub-decimetre-scale geoscientific samples. The technique is commonly used for the characterisation of outcrops, ...

Mulrooney, Mark Joseph; Larsen, Leif; Van Stappen, Jeroen; Rismyhr, Bjarte; Senger, Kim; Braathen, Alvar; Olaussen, Snorre; Mørk, Mai Britt Engeness; Ogata, Kei; Cnudde, Veerle (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)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. ...

Ogata, Kei; Weert, Annelotte; Betlem, Peter; Birchall, Thomas; Senger, Kim (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Sedimentary injectites are increasingly documented in many hydrocarbon plays at various scales, either interpreted as potential risks (e.g., topseal bypass, a drilling hazard) or benefits (e.g., reservoir interconnection, ...

Anell, Ingrid Margareta; Zuchuat, Valentin; Röhnert, A.D.; Smyrak-Sikora, Aleksandra; Buckley, Simon John; Lord, Gareth Steven; Maher, H.; Midtkandal, Ivar; Ogata, Kei; Olaussen, Snorre; Osmundsen, Per Terje; Braathen, Alvar (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)The study describes the depositional development and sediment partitioning in a prograding paralic Triassic succession. The deposits are associated with the advance of large prism‐scale clinoforms across a shallower platform ...
