As announced by the NPD yesterday, the highly anticipated appraisal well (6507/5-11) on ConocoPhillips’ Slagugle discovery has resulted in a significant downgrade of its size.
Named “Explorer of the Year 2020” by GeoPublishing on the back of the American explorer’s success in the Norwegian Sea in recent years (Warka, Slagugle), the completion of this appraisal campaign will no doubt be a disappointment.
Based on the results in the discovery well (6507/5-10S) completed in November 2020, Slagugle was thought to host between 75 and 200 MMb of recoverable oil. Now, the discovery is likely to contain between 37 and 82 MMbo recoverable instead.
Attend the NCS Exploration – Recent Discoveries Conference in Oslo next week (8 & 9 June) and hear about two other Norwegian Sea appraisal campaigns that shed another light on reservoir architecture and field development strategies: Bergknapp and Fenja.
You will also hear more about: Toppand, Apodida, Røver Nord, Dugong Tail, Segment D, Hamlet, Rolvsnes, King/Prince, Wisting, Salina, Bask, Rødhette, Isflak, Skavl, Culzean (UK), Mugnetind, Lyderhorn, Gomez, Tyrihans Ile North & Warka.
In addition, there will be talks about frontier exploration in the Norwegian Sea, a debate on source rocks and implications on hydrocarbon generation and much more.
The appraisal well also had a secondary target in the Paleocene Tang Formation, but sandstones were not encountered in this stratigraphic interval. In the primary target, the well did encounter sandstones in the Åre Formation in the Lower Jurassic and Grey Beds in the Upper Triassic at a total thickness of 122 metres with very good reservoir quality. However, no hydrocarbons were encountered.
Subsequent injectivity tests showed good flow properties in all zones, and communication in the Grey Beds between wells 6507/5-10S and 6507/5-11.
