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 ... -
Geochemical Characterisation of Oils and Sediments from Cuba and Jamaica; Implications for the Northern Petroleum System
Skarstein, Guro Laurentze Sætre (Masteroppgave/UIS-TN-IER/2018;, Master thesis, 2018-07-06)The Caribbean plate has a complex tectonic history and its petroleum potential is relatively unexplored. Jamaica and a large part of Cuba were once part of the Great Arc of the Caribbean (GAC), which was later deformed ... -
Lateral compositional variations in the Upper Jurassic source rock in the southwestern Barents Sea – an organic or inorganic disclosure
Helleren, Solveig (Masteroppgave/UIS-TN-IER/2019;, Master thesis, 2019-06)Prominent high-value gamma-ray spikes in the maximum flooding surfaces of the Alge Member of the Hekkingen Formation display an uncommon stratigraphic and regional variation in the southwestern Barents Sea. The variation ... -
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 ... -
Repeated post-Caledonian intra-cratonic rifting in the central North Sea: Evidence from the volcanic record in the Embla oil field
Lundmark, Anders Mattias; Gabrielsen, Roy Helge; Strand, Tor; Ohm, Sverre Ekrene (Journal article; Peer reviewed, 2017-11)Intrusive and extrusive mafic igneous rocks in the Embla oil field, central North Sea, testify to repeated post-Caledonian magmatism on the northern flank of the Mid North Sea High. The igneous rocks are highly clay- and ... -
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 ... -
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 ...
