As part of the NSTA’s published 2018/19Activity Plan, the NSTA is publishing a set of regional geological maps for the Mid North Sea High and Forth Approaches areas of the UKCS. These maps represent the fifth set of deliverables from a 3 year contract with Lloyd’s Register (LR) to produce a series of maps and associated databases for the whole of the UKCS.
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 seismic interpretation work carried out by Heriot-Watt University (Rachel Brackenridge), the 21CXRM Palaeozoic project (which is now available in the public domain), CGG’s Target database and relevant products available via the BGS’s Offshore Geoindex. CDA is 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 maps are being produced for the main geological time intervals e.g. Paleocene, Lower Cretaceous, Upper Jurassic. Each time interval includes the following products:
• Depth structure maps
• Isochore maps
• Subcrop & supercrop maps
• Structural elements maps
• Depositional facies maps
• Reservoir distribution maps
• Source rock maps
• Well penetration maps
• Hydrocarbon occurrence maps
