Reservoir quality characterization and prediction of deeply buried clay coated sandstones on the NCS, Examples from the South Western Barents Sea and Northern North Sea
In recent years, petroleum exploration that utilizes existing infrastructure to save time, cost and lower production related C02 emissions have become more important. This strategy require more emphasis on deeply buried prospects which call for a thorough understanding of geological processes that a...
