Large-scale changes in lithofacies and stratigraphic architecture resulting from relative sea-level changes have been a prime research focus for the past few decades. Within industry, prediction of hydrocarbon play elements using sequence stratigraphic techniques is well-established. In 2001 we demonstrated the veracity of a sequence stratigraphic model for the Arabian Plate . Ongoing work, incorporating nearly all of Earths sedimentary basins, now demonstrates the occurrence of 118 biostratigraphically constrained sequences that are observed independent of tectonics or sediment supply and are therefore global in nature. The rapidity and magnitude of sea-level changes inferred from our model implicates eustatic forcing.
The East Greenland Margin is widely regarded as a major petroleum province of the future. Recent estimates put the total recoverable reserves for the area at 31,387 million barrels of oil and oil-equivalent natural gas . To date no exploratory wells have been drilled in this region, although excellent outcrop exposures indicate the presence of several potential source rocks and reservoir opportunities. Oil seeps and oil impregnated sediments evidence an active petroleum system.
Biostratigraphically constrained sections provide a framework within which our global sequence stratigraphy model can be applied. Here the main source and reservoir intervals are reviewed within this sequence stratigraphic context to provide a regional perspective. Potential petroleum plays are analysed and comparisons are made with the known petroleum systems of the Norwegian Barents Shelf.
