Shallow hydrocarbon gas in the northern Jutland-Kattegat region, Denmark

Abstract

The gas field has a NW to SE areal extent subparallel to the northern limit of the Danish sub-basin and the major fault-systems of the Fennoscandian border zone. This distribution coincides with the occurences of a tectonic depression in the pre-Quaternary surface which primarily is filled in with Eemian and Weichselian marine sediments. The gas most likely derives from degradation of organic material in the Upper Pleistocene marine sediments themselves and is subsequently trapped in restricted reservoirs of sand and gravel. -from Authors
