The most prominent clastic reservoir rocks in eastern part of the Norwegian-Danish Basin (onshore Denmark) are the Triassic-Jurassoc sediments comprising the Bunter Sandstone Formation, Skagerrak Formation, Gassum Formation and the Haldager Sand Formation. The Bunter Sandstone Formation is deposited by ephemeral streams, terminal fans or aeolian activity in an arid (hot) climate. The Skagerrak Formation comprises sediments from alluvial fans grading into braided streams. The lower part of the Skagerrak Formation is northern equivalent to the Bunter Sandstone Formation occurring mainly south of the Ringkøbing-Fyn High, whereas the upper part is contemporaneous with the Gassum Formation. The Gassum Formation and the Haldager Sand formations are deposited in fluvial, parallic and shallow marine environment under humid and vegetated conditions.
