Gullfaks South lies in blocks 34/10 and 33/12 in the northern North Sea, where water depths are 130-220 metres.

These blocks were awarded in 1978/1995 and 1973 (carve-out 1998) respectively.

Gullfaks South is a satellite to the main Gullfaks field, developed with subsea production installations.

The first development phase was approved in March 1996, and came on stream in October 1998. Phase II was approved in June 1998, coming on stream in October 2001.

Phase I covers the production of oil and condensate, with reinjection of associated gas.

The eight subsea installations in this part of the development are tied back to the Gullfaks A platform for processing, storage and loading.

Phase II covers production and export of gas and associated liquids, with subsea installations tied back to both Gullfaks A and Gullfaks C.

The gas is piped from Gullfaks to the Statpipe trunkline and on to Kårstø north of Stavanger.

Oil and condensate (light oil) are stabilised and stored on the A and C platforms before being exported by ship.

Gullfaks South also includes the separate Rimfaks and Gullveig structures.
