All of the Arctic Eurasian Basins – the Barents and Kara Seas and the adjacent parts of the Pechora and West Siberian basins – have intracratonic settings and were affected by phases of intracratonic rifting during Riphean, Early Palaeozoic, Devonian–Early Carboniferous, Early Triassic, Jurassic and Cenozoic times. Often these stages were simultaneous at remote areas. The rifting led to the development of extensional sag basins giving thick sedimentary complexes associated with linear rifts and creating trends favourable for hydrocarbon generation. These trends are defined by the major fault complexes bordering them and include linear positive inverted structures and thick sedimentary complexes. The tectonic processes within these trends influenced the later structuring of the whole basin and the distribution of hydrocarbons. Hydrocarbon generation started long before the present basins’ structural configuration formed, and oil and gas kitchens were associated mainly with extensional parts of the basins. Later phases of rifting and extension affected both the ancient oil and gas kitchens and the younger ones. Inversion caused trapping and affected fluid migration, mixing the petroleum systems. Inverted structures in the old rifts have the highest potential for large hydrocarbons accumulations but, in highly uplifted areas affected by faulting and erosion, exploration risk is high.
Figures & Tables
The vast Arctic region contains nine proven petroleum provinces with giant resources but over half of the sedimentary basins are completely undrilled, making the region the last major frontier for conventional oil and gas exploration. This book provides a comprehensive overview of the geology and the petroleum potential of the Arctic. Nine papers offer a circum-Arctic perspective on the Phanerozoic tectonic and palaeogeographic evolution, the currently recognized sedimentary basins, the gravity and magnetic fields and, perhaps most importantly, the petroleum resources and yet-to-find potential of the basins. The remaining 41 papers provide data-rich, geological and geophysical analyses and individual oil and gas assessments of specific basins throughout the Arctic. These detailed and well illustrated studies cover the continental areas of Laurentia, Baltica and Siberia and the Arctic Ocean. Of special interest are the 13 papers providing new data and interpretations on the extensive, little known, but promising, basins of Russia.
A DVD is provided inside the back of the book, that contains PDFs of all papers plus all related Supplementary Publications.
