North Sea Inner Moray Firth

Located in the Inner Moray Firth Basin, directly updip of the Beatrice Field, the Dunrobin Prospect is a low-cost opportunity to test prospective resources of >100 mmboe.
The prospect comprises a large rotated fault block, covering up to 45 km2. High-quality Jurassic sandstone reservoirs correlate on seismic to nearby well control.

Reabold NS 36%; Baron Oil 32%; Upland Resources 32%

Dunrobin Prospect: structure and prospective resource summary

  • The Dunrobin Prospect is a structural closure comprising two linked rotated fault blocks, covering up to 47 km2
  • The lowest closing contour for Dunrobin includes the whole structure, for which the Pmean of the prospective resource distribution for the Jurassic reservoir interval is 144 mmboe.
    Dunrobin ‘West’ is separate from ‘Central & East’ at the P50 and P90 closing contours, so prospective resources have been estimated for both separate and combined structures
  • Dunrobin West has a thicker Jurassic reservoir interval and has a Pmean prospective resource of 107 mmboe
  • Dunrobin Central and East has a Pmean prospective resource of 39 mmboe
  • Geological chance of success is estimated at 39% for Dunrobin Jurassic reservoirs
  • Dunrobin is located directly updip of the Beatrice source kitchen
  • The crest of the Dunrobin West structure exhibits a clear gas / amplitude response on seismic, giving high confidence in the effectiveness of the top and lateral seal
  • Excellent-quality Jurassic sandstone reservoir section is correlated from Beatrice and nearby wells to Dunrobin on good-quality seismic data
  • The key subsurface risk is preservation of oil at low temperatures, as the crest of Dunrobin West is located at 380m subsea (gas-oil contact at 470m subsea)
