Compositional variation of the Zechstein Group in the Norwegian North sea: Implications for underground storage in salt caverns
Marín, Dora; Cardozo, Nestor; Escalona Varela, Alejandro (Peer reviewed; Journal article, 2023)Halite beds in the upper Permian Zechstein Group represent an opportunity for the future development of underground storage caverns. However, geological factors such as lithological heterogeneities, cap rock characteristics ... -
Holistic 3D Model of an Urban Area in Norway: An Integration of Geophysical, Geotechnical, Remote Sensing, and Geological Methods
Gutierrez Mozo, Ivan David; Weibull, Wiktor Waldemar; Watson, Lisa; Olsen, Thomas Meldahl; Escalona Varela, Alejandro (Peer reviewed; Journal article, 2023)Understanding the distribution and characterization of natural and non-natural materials on the surface and near-subsurface is important for the development of infrastructure projects. This may be a challenge in highly ... -

The Impact of Salt Tectonics on the Thermal Evolution and the Petroleum System of Confined Rift Basins: Insights from Basin Modeling of the Nordkapp Basin, Norwegian Barents Sea
Cedeno Motta, Andres Felipe; Rojo Moraleda, Luis Alberto; Cardozo Diaz, Nestor Fernando; Centeno, Luis; Escalona Varela, Alejandro (Peer reviewed; Journal article, 2019-07)Although the thermal effect of large salt tongues and allochthonous salt sheets in passive margins is described in the literature, little is known about the thermal effect of salt structures in confined rift basins where ... -
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 ... -
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 ...
