Oseberg South (Norwegian: Oseberg Sør) is an offshore oil field in the North Sea, located from the coastline and south of Oseberg oil field. Oseberg Sør was discovered in 1984.[1] The field was developed with a fixed production, drilling and quarters (PDQ) 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 the Oseberg Sør was approved in 1977. Recent updates include approval of J structure[2] which started producing in November 2006 and Oseberg Sør G Sentral which has been developed in 2009.[3]
The sea depth at location is 100m (300feet). The platform at Oseberg Sør which was built for drilling of 30 wells[4] includes a 125m (410feet) tall steel jacket which supports a total topside dry weight of nearly 14,000 tonnes. It also includes a 100-bed capacity living quarters, first stage processing facilities, power generation and utility systems and a high performance drilling package. The field produces up to of oil, of natural gas and of water per day[5] The field consists of ten accumulations within Jurassic sandstones, all in separate structures. The reservoirs lie at a depth of 2200-. Production lifetime is estimated at 20 years.[3] [6] It is believed to contain a total of of recoverable oil and up to of recoverable gas.[4]
