North Rockall Trough Stratigraphic Database

The DTI release of the 154/1-1 Benbecular discovery well was the catalyst for the inclusion of the North Rockall Trough wells into the Ichron Atlantic margin datasets.

The database includes 17 wells in total wells of which 11 are from the North Rockall Trough area encompassing Quads 153, 154, 163 and 164, and 6 wells from the Foinaven Sub-basin and the Faroes licence area. These are included in the database to highlight the stratigraphic relationship of the basalts and volcanoclastics between these areas and also to demonstrate the consistency of the sequence subdivision.

An example of this is the age of the Benbecular reservoir sands which are presented within the context of the Ichron sequences and calibration with the phases of sand deposition known to occur in the Foinaven Sub-basin.
