Oseberg South is an offshore oil field in the North Sea, located from the coastline and south of Oseberg oil field. Oseberg South was discovered in 1984. The field was developed with a fixed production, drilling and quarters facility and is operated by Statoil. The first stage phase processing is done at the Oseberg Øst platform. The second and third phase processing of oil is done at the Oseberg Field Center and it is then transported to Sture Terminal in Norway through the Oseberg Transport System. The development of Oseberg South was approved in 1977. Recent updates include approval of J structure which started producing in November 2006 and Oseberg Sør G Sentral which has been developed in 2009.
