Frontier Science and Exploration: The Atlantic - Arctic

We propose linking academic and industrial research and data exchange in order to refine plate reconstruction and basin evolution models, characterize continental-ocean boundaries (COBs) and investigate links between Large Igneous Provinces (LIPs) and Pla te Tectonics. State-of-the-art understanding of geological processes related to plate boundaries and plate dynamics is essential to refine and/or develop new hydrocarbon exploration models, and we propose to reconstruct the Arctic-Atlantic margins with em phasis on the evolution of the Canada-Eurasia Basin, Barents Sea, NE Atlantic, Labrador Sea and South Atlantic. The transitional areas and adjacent COBs are poorly understood with respect to crustal structure, genesis, heat generation, and subsidence. The combined use of magnetics, deep/shallow seismics, gravity inversion methods, plate reconstructions, and regional geologic synthesis will advance understanding of what constitutes the COB. The relationships between LIPs, plate tectonics, and mantle proces ses are disputed, as is their influence on hydrocarbon prospectivity. Increased transient heat flow stemming from plume-related magmatism increases maturation, but positive or negative effects depend on a given play model. Conversely, increased heat flow clearly can have a negative effect on reservoir quality. Exploration for hydrocarbons has reached a mature stage in the North Sea. At the same time the new mid-Norwegian exploration frontier has not proven to be as prolific as anticipated. This project is therefore aimed at adding valuable input focused on exploration in areas pushed to the very limit of the continental margins. The project addresses geoscience competence-building in frontier exploration areas, and is oriented toward the inevitable expans ion of Norwegian exploration into the international arena.
