ALT Location map of the N05-A discovery and surrounding prospects. The wind farm is shown in green and the currently drilling N04-3 exploration well is situated just north of the N05-A cluster. The E-W trending green line indicates the northern pinch-out line of the classic Slochteren Upper Permian sandstone fairway. The Rotliegend sandstones found in the area around N05-A are slightly older, thinner (25-40 m) and have a more patchy distribution.

ALT Location of N05-1 Ruby discovery as well as the location of the upcoming N04-3 exploration well. The green line on the map indicates where the Slochteren sandstones pinch out in a northerly direction – note that the Groningen field, with its gas reservoired in Slochteren sandstones, is just south of this line.

ALT State of play in the North Sea region with regards to wind farms (realised and planned), CO2 storage licences and projects and geothermal exploration licences, in conjunction with locations of current oil and gas fields and planned exploration wells.

ALT Overview of oil and gas fields in the area. The fields included in the acquisition are indicated in bold. We assume that the Scheerhorn oil field is the same as the Adorf-Scheerhorn mentioned in the press release.

ALT Exploration wells spudded in and around the North Sea in 2020.
