The North Sea offers those exploring for oil a new and unusual geologic province. Gas fields in the S. sector, discovered during the past 8 yr, followed finding Holland's large Groningen gas field. These reservoirs store mostly methane, derived from Carboniferous strata coal deposited about 350 m.y. ago. The gas migrated upward until it found porous sandstones and limestones at the base and top of the Permian series. Although the search for more gas continues, and there is always a chance that stratigraphic traps may hold a great deal more than has been found in dome-shaped underground structures, new interest in the North Sea is to find oil, produced traditionally from decaying marine sediments, rather than as an adjunct to fresh water coal deposits. An approximate cross section of the North Sea geology, spanning between Scotland and Norway, is presented. Likewise, a schematic of the North Sea Basin tectonics and the known fields of oil and gas in the northern North Sea are identified.
