Summary

All data released with this set of geological maps is public domain data. The project has, however, benefited from a number of additional third-party data sources which have been used to help inform final maps and/or derive interpreted products. These include the 21CXRM Palaeozoic project (which is now available in the public domain),the Southern Permian Basin Atlas (SPBA),PGS’s North Sea Digital Atlas and East Shetland Platform seismic interpretation project, Frogtech’s East Shetland Platform Project, IGI’s Source Rock Evaluation for the East Shetland Platform, research data from the University of Aberdeen, seismic interpretation work and other geological studies carried out by Durham University on the SW Approaches, seismic interpretation work carried out by Heriot-Watt University on the Mid North Sea High, seismic interpretation work carried out by Aberdeen University on the Rockall area CGG’s Target database and relevant products available via the BGS’s Offshore Geoindex. TGS are gratefully acknowledged for providing joined digital log data from LogLinePlus to enable the production of sand flag curves. Schlumberger, TGS and BP are acknowledged for providing additional seismic data to help QC interpretation carried out within the project and CDA are also kindly acknowledged for their support in downloading and providing much of the released well data to LR as part of this project. Due to the high level, regional nature of the project, the depth structure and structural elements maps have been produced for the main geological time intervals, e.g. Paleocene, Lower Cretaceous, Upper Jurassic. Depositional facies maps and reservoir distribution maps were produced for a higher number of stratigraphic intervals such as the Danian, Selandian and Thanetian (Paleocene).

The following products are available:

•Depth structure maps

•Isochore maps

•Structural elements maps

•Depositional facies maps

•Reservoir distribution maps

•Well penetration maps

•Hydrocarbon occurrence maps

•Drill stem tests

•Well tops (Groups, Formation and Members)

•Sand data (N/G, sand thickness)
