Over the past 75 years, hydrocarbon exploration of Arctic regions north of the Arctic Circle (66°N) has yielded some 450 discoveries which collectively account for 2.5% of global conventional liquids discovered to date and 15.5% of the world's discovered conventional natural gas. Accumulations occur in rocks ranging from Cambrian to Pleistocene in age but 94% of all Arctic hydrocarbon resources occur in clastic reservoirs of Mesozoic age. Although discoveries have been reported from 15 different basins onshore and offshore Alaska, Canada, Norway and Russia, 75% of all discovered resources are located in the portion of Russia's Western Siberia Basin that lies north of 66°N. Hydrocarbon accumulations discovered in the Arctic region have been generated from nearly 40 different petroleum systems. The main elements of these petroleum systems such as sources, reservoirs and seals are described and the chronology of these depositional events is summarized in two chronologic charts representing the Eastern and Western hemispheres.
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.
