Oseberg is an offshore
oil field with a gas cap in the
North Sea located northwest of the city of
Bergen on the southwestern coast of
Norway. The field, which is 25 km long by 7 km wide, was discovered in 1979 and its development is known to be one of the significant milestones in emergence of Norway's independent
oil and gas industry. The Oseberg field was named after
Oseberg ship, one of Norway's most significant archeological discoveries. The ancient Viking ship from the early 9th century was discovered in a 1904 historical excavation of a burial mound at the Oseberg Farm, south of
Oslo.
