Gina Krog (previously Dagny), which was originally a minor gas discovery just north of Sleipner, is a field that has been considered for development on a number of occasions since it was discovered in 1974.

When oil and gas were proven in the neighbouring structure Gina Krog Øst (previously Dagny) in 2007, the Gina Krog landscape was reviewed again. Further delineation during the period 2008 to 2011 determined a contact between Gina Krog and Gina Krog Øst and confirmed substantial volumes of oil under the entire structure.

The development of Gina Krog, which will be among Statoil's major new developments with an estimated 225 million barrels of oil and gas, illustrates the importance of exploring and developing in mature areas with established infrastructure. Now we can extend the lifetime and exploit the available capacity on Sleipner for many years to come.


Gas was proven in the Gina Krog (previously Dagny) discovery as early as in the 1970s, just north of the Sleipner Vest field in the central part of the North Sea. In 2007, gas, condensate and oil were discovered in the Ermintrude prospect. Appraisal wells drilled on Gina Krog from 2008 to 2011 proved an oil column under the gas.

The Gina Krog partners submitted a Plan for Development and Operation (PDO) in December 2012. An impact assessment was submitted for consultation in October 2012.

The plan is to develop Gina Krog with a platform resting on the seabed, while the wells will be drilled with a mobile jack-up drilling rig. The liquid will be transported via a tanker, and the gas via the Sleipner field.

The Dagny field was renamed Gina Krog 8 March 2013
