Viking Graben
4 May 2017

Slightly deviated exploration well on the Ardbeg prospect, requiring up-dip seal to the west against Upper Triassic on the Dunbar South Horst and dip-closure to the east. Upper Brent reservoir objectives. Main hole was junked at 7,940 ft in the Upper Cretaceous. Sidetrack encountered thin unprognosed sands in the Heather from 12,278 ft and thick Unst and Muck sands from 12,609 ft before encountering the Balta Sandstone objective 12,921 ft (12,791 ft TVDSS). All sands showed residual oil saturation but were proved water-wet from logs.
