Phase 1 Faroes/UKCS Stratigraphic Database

The 101st DTI well release of the Cambo discovery well 204/10-1 and the Marjun appraisal well 204/16-1, in combination with decision by the Faroese Earth and Energy Directorate to release wells 6004/12-1/1Z (Svinoy prospect), 6004/16-1Z (Marjun, prospect and discovery) and 6005/15-1 (Longan prospect) provided the background to the Phase 1 Faroes/UKCS Stratigraphic Database.

The decision was made to integrate selected wells from the Foinaven Sub-basin Stratigraphic Database in order to provide a stratigraphic overview of the new wells adjacent to the Faroes/UKCS boundary within the context of the discovery wells from the Foinaven, Alligin and Suilven Fields.

A total of 30 wells are included in the study centred around Quads 6004 and 204, however a number of additional wells are included from Quad 205 to demonstrate the stratigraphic relationship of the basalts within the Flett Formation. The Ichron sequences are calibrated with the UKOOA/BGS lithostratigraphic nomenclature and provide a robust and reliable stratigraphic framework within which reservoir sections are correlated and confident seismic well ties are presented.
