Utsira High ( Norwegian: Utsirahøgda) is a basement high and horst in the southwest of the Norwegian continental shelf. [1] It lies east of the Viking Graben and west of the Stord and Egersund basins 190 km west of Stavanger. [2] [3] It was on the Balder oil field at the flank of the Utsira High that oil was first discovered in Norway in 1967. [3]
The basement is of Utsira High is composed of granite that formed in Ordovician times. [1] Parts of these granites contain saprolite and saprock that formed from weathering above sea level during the Early Mesozoic. [2] before they became buried in Late Jurassic and Early Cretaceous-aged sandstone. [1] These weathered rocks may be unconventional petroleum reservoirs. [2]
The strandflat at Bømlo island is considered a sedimentary rock-free equivalent to the Utsira High. [1]
