Statoil and partner Petoro have proven considerable additional resources in the Shetland Group/Lista Formation in the Gullfaks licence (Norway).
Indications of hydrocarbons in the Shetland Group/Lista Formation in the Gullfaks licence have been known for a long time, but they have not yet been developed due to poor reservoir qualities. A new well test in this interval however indicates good flow rates. Production well 34/10-A-8 on the Gullfaks A platform, where the well test is carried out, currently provides a high and stable production of 7,500 bbl/day. The well has produced nearly 1 mbl since December 2012.
The discovery is estimated to contain in the range of 40-150 million recoverable barrels of oil equivalents. However, this resource estimate involves a high degree of uncertainty. While the models indicate further upside potential, data gathering and studies are currently ongoing to clarify the potential and further development of these resources.
Located in the Tampen area in the northern North Sea, Gullfaks came on stream in December 1986. The field development consists of three permanent installations, which have produced more than 2.4 Gbl of oil and more than 56 bcm of gas. The licensees of the Gullfaks Field are operator Statoil with 70% and partner Petoro with 30%.
