Discovery of shale gas in organic rich Jurassic successions, Adventdalen, Central Spitsbergen, Norway
Ohm, Sverre Ekrene; Larsen, Leif; Olaussen, Snorre; Senger, Kim; Birchall, Thomas; Demchuk, Thomas; Hodson, Andrew; Johansen, Ingar; Titlestad, Geir Ove; Karlsen, Dag Arild; Braathen, Alvar (Journal article; Peer reviewed, 2020-01)Thermogenic dry gas flowed from Jurassic sections in the DH5R research well drilled onshore in Adventdalen, central Spitsbergen, Arctic Norway. The DH5R gas originates from the organic-rich units of the mudstone-dominated ... -
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 (Journal article; Peer reviewed, 2018-11)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. ... -
The Middle Jurassic to lowermost Cretaceous in the SW Barents Sea: Interplay between tectonics, coarse-grained sediment supply and organic matter preservation
Marin Restrepo, Dora Luz; Helleren, Solveig; Escalona Varela, Alejandro; Olaussen, Snorre; Cedeno Motta, Andres Felipe; Nøhr-Hansen, Henrik; Ohm, Sverre Ekrene (Peer reviewed; Journal article, 2020)Syn‐rift successions contain both prolific organic‐rich and coarse‐grained rocks, but these rocks are usually studied independently. Thus, the interplay among organic matter deposition, tectonics and sediment supply is not ... -
Resistivity of reservoir sandstones and organic rich shales on the Barents Shelf: Implications for interpreting CSEM data
Senger, Kim; Birchall, Thomas; Betlem, Peter; Ogata, Kei; Ohm, Sverre Ekrene; Olaussen, Snorre; Paulsen, Renate Strugstad (Peer reviewed; Journal article, 2021-11)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 ... -
Unravelling key controls on the rift climax to post-rift fill of marine rift basins: insights from 3D seismic analysis of the Lower Cretaceous of the Hammerfest Basin, SW Barents Sea
Marin Restrepo, Dora Luz; Escalona Varela, Alejandro; Grundvåg, Sten-Andreas; Olaussen, Snorre; Sandvik, Sara; Sliwinska, Kasia (Journal article, 2017-10)In this study, we investigate key factors controlling the rift climax to post-rift marine basin fill. We use two- and three-dimensional seismic data in combination with sedimentological core descriptions from the Hammerfest ... -
Upper Jurassic to Lower Cretaceous source rocks in the Norwegian Barents Sea, part I: Organic geochemical, petrographic, and paleogeographic investigations.
Cedeno Motta, Andres Felipe; Ohm, Sverre Ekrene; Escalona Varela, Alejandro; Marin Restrepo, Dora Luz; Olaussen, Snorre; Demchuk, Thomas (Peer reviewed; Journal article, 2021-09)This study provides a subregional to regional characterization of organofacies changes within the two members of the Upper Jurassic to Lower Cretaceous Hekkingen Formation (i.e. Alge and Krill) by integrating geochemical ... -
Upper Jurassic to Lower Cretaceous source rocks in the Norwegian Barents Sea, part II: Insights from open- and closed-system pyrolysis experiments
Cedeno Motta, Andres Felipe; Ohm, Sverre Ekrene; Escalona Varela, Alejandro; Marin Restrepo, Dora Luz; Olaussen, Snorre; Demchuk, Thomas (Peer reviewed; Journal article, 2021-10)The petroleum generation potential of Upper Jurassic to Lower Cretaceous organic rich shales from the southwestern Barents Sea was evaluated using bulk and quantitative pyrolysis analysis. Fifteen thermally-immature samples ...
