Country Summary

Outer Rough Blocks – High impact oil-prone prospectivity in the under-explored eastern margin of the Outer Rough basin.

Location and Geology

The Outer Rough Blocks cover an area of 284.9 km2 and are located on the northernmost margin of the Southern Permian Basin on the western limit of the Danish offshore, bounded to the west by the UK median line and to the south by the German median line. Water depths are approximately 70m and the nearby fields include the Fife/Fergus/Flora fields some 10km to the west in UK waters and the Valhall field some 20km north in Norwegian waters.

The Outer Rough Blocks acreage was high graded following a regional assessment of an area encompassing five countries and enabled by careful cross border re-interpretation of some 1,200 km2 of 3D seismic, a thorough geological well review, and the generation of a proprietary seismic inversion volume. Two major stratigraphic prospects have been matured within the Upper Jurassic shoreface sandstones. Such reservoirs have been proven as oil producers in the neighbouring UK Fife and Fergus fields, and are mapped to extend into Denmark, where they have been penetrated by two wells, Wessel-1 and Saxo-1. Both these on licence wells targeted structural traps in sub optimal locations for charge access though proved the potential for excellent reservoir quality and development. The mean in place volumes suggest a yet-to-find stratigraphic potential of over a billion barrel of oil in place within the Jurassic section.

Equity Interests

Licence 14/16, which covers Blocks 5603/30, 5603/31 and 5503/2, was awarded as part of the 7th Danish offshore licensing round, in April 2016. Discover through its wholly owned subsidiary, Hansa Hydrocarbons Limited, holds a 32% non-operated interest in the licence. The remaining licence interests are held by Edison International SPA (48% as operator) and the Nordsøfonden 20% (state participation).

Operator

Licence 14/16 is operated by Edison International SPA (https://www.edison.it/en/norway-and-denmark).

Licence Status

The licence term is six years with a decision at the end of the second year to either acquire a new 3D seismic survey or to drill an exploration well. However, operator Edison International SPA asked for a one-year extension, so that the decision is postponed until April 2019. The firm work programme consists of reprocessing existing 3D seismic data in order to improve the structural definition across the area and basin modelling studies to address the key risk of charge. Additionally, a further inversion volume will be generated from the latest 3D seismic survey to refine prospect mapping and definition. With the results of this initial work programme, the joint venture partners will be in a position to decide whether to progress to a second phase comprising either an exploration well or seismic commitment.
