Skrugard Seismic Section


Seismic and 3D CSEM profile across the the Bjørnøyrenna Basin and the Skrugard discovery well 7219/8-1 S. Notice the excellent match between the structural information provided by the seismic section and the resistivity profile with a conductive Tertiary resting on top of a resistive Cretaceous-Jurassic fault block with the Skrugard discovery well 7219/8-1 S. As the downthrown block is conductive, a better understanding of such resistivity variations is an additional key for breaking the basin code. Source: Aker Geo

The structural trend in the CSEM map corresponds to an offset in basin overall NNE-SSW trend. Source: Aker Geo



Statoil Havis Skrugard Area, Barents Sea



Statoil estimates the volumes in Havis to be between 200 and 300 million barrels of recoverable oil equivalents (o.e.). The provisional, updated total volume estimate for the Skrugard and Havis discoveries in PL532 is in the region of 400-600 million barrels of recoverable oil equivalents.

Havis lies approximately 7 kilometres southwest of the Skrugard discovery, made in April of last year. Havis lies within the same production licence, but forms an independent structure. There is no communication between the two discoveries.

Moreover, Havis and Skrugard prove that persistence and long-term thinking bear fruits. Statoil has been exploring in the Barents Sea for more than 30 years and the company has been involved in 88 of a total 92 exploration wells drilled in the area. This has resulted in continuous competence building and a deep understanding of the hydrocarbon systems in the Barents Sea.
