Block 15/21g Spaniards
(Licence P1655)
(Nautical 21%)

Situated in the Witch Ground Graben in the Outer Moray Firth, Block 15/21g is immediately west of the Scott Field and contains the large Spaniards Jurassic prospect downdip from the 15/21-38 well which tested 2,660 bopd of 25° API oil from the Galley Sandstone.

Seismic amplitude mapping indicates the reservoir thickens downdip both to the north-east and north-west of the discovery well. Further pressure analysis from the well suggests the potential for a long oil column. Additional prospectivity has been mapped in the Dirk Sand (Ryazanian to Upper Volgian age) which is derived off the Halibut Horst and deposited as a sand apron to the north, pinching out to the east.

A cost sharing agreement has been reached with the enlarged Joint Venture group. Planning is under way to drill a well in Q2 2012.
