NEOGENE I (2010-2012)


Neogene Uplift of the Barents Sea - phase 1

Fennoscandia has experienced major uplift in post-glacial time. The rate of uplift along the coasts is so high that its effects have been observed within one generation. In the northern Gulf of Bothnia uplift is occurring at 9 mm/yr; similar uplift rates are observed also on Svalbard.

Numerous glaciations preceding the last one also caused rapid glacial erosion and subsequent differential uplift and tilting. It is commonly envisioned to have led to spillage of hydrocarbons, phase transition from oil to gas, expansion of gas, seal failure, cooling of source rocks, and slope instability. In addition to glacial erosion, repeated ice and sediment loading had great influence on hydrocarbon migration routes, the temperature history and maturation. Detailed control on the glacial erosion, sediment deposition and ice loads (i.e. the glacial history) is therefore an important and insufficiently utilized factor for identification of the remaining hydrocarbon resources in the Barents Sea.

The objective of the project is to enhance the understanding of Plio-Pleistocene glaciations and their effects on petroleum systems in the Barents Sea.

This project ended in December 2012, and was sponsored by 8 oil companies and the Research Council of Norway. 

The results of this project are available to the participating companies.
