Reports, images, GIS and gridded products describing the Palaeozoic geology and conventional petroleum systems of parts of the UK offshore. Devonian and Carboniferous rocks are the focus in and around the Mid North Sea High, Central North Sea, the Moray Firth and Orcadian Basin. In the greater Irish Sea area, Carboniferous rocks are described. The peer-reviewed products were produced for the 21CXRM Palaeozoic Project by BGS for DECC/OGA, Oil and Gas UK and oil company sponsors between November 2014 and May 2016, to improve regional digital datasets and knowledge of the underexplored Palaeozoic petroleum systems, and to stimulate exploration. The petroleum systems analysis was based on new interpretations of extensive well, seismic, gravity-magnetic and source rock datasets, integrated with petrophysical studies, basin modelling and UK onshore knowledge. Released data were collated and interpreted, and interpretations of unreleased data were included with agreement of the data owners. Unreleased raw data is excluded, as is the UK Government Seismic data released in 2016. The datasets are applicable for use at scales between 1: 750,000 to 1: 3,000,000.

Reports, images, GIS and gridded products describing the Palaeozoic geology and conventional petroleum in and around the Mid North Sea High (Quadrants 25-44). Covering a large area of the Central North Sea from the Forth Approaches to the northern side of the Southern North Sea, the focus is on Devonian and Carboniferous rocks.

GIS versions of a regional structural summary and palaeogeographic reconstructions describing the Palaeozoic geology of parts of the UK offshore and onshore, plus a set of summary posters and a summary presentation capturing the conventional petroleum systems. Devonian and Carboniferous rocks are the focus in and around the Mid North Sea High, Central North Sea, the Moray Firth and Orcadian Basin. In the greater Irish Sea area, Carboniferous rocks are described.

Released data were collated and interpreted, and interpretations of unreleased data were included with agreement of the data owners. Unreleased raw data is excluded, as is the UK Government Seismic data released in 2016. The GIS layers were digitised from figures prepared for project reports and are applicable for use at scales between 1:1,000,000 and 1:3,000,000.

This zipped folder contains data from a study, by petroleum geoscience team at the BGS, which was created as part of the 21st Century exploration Roadmap (21CXRM). The petroleum geoscience team worked with the UK North Sea Transition Authority (NSTA), Oil and Gas UK and a consortium of over 45 oil companies to evaluate the remaining petroleum potential of previously overlooked or unfashionable areas of the UK Continental Shelf.The 21st Century Exploration Roadmap (21CXRM): Palaeozoic Project is part of the UK Government's endeavour to maximise the economic recovery of hydrocarbons on the UK Continental Shelf (UKCS), in response to the Wood Review.A study of the Palaeozoic of the UKCS was one of the first projects to be implemented as part of the 21st Century Exploration Roadmap. Multidisciplinary studies further defined the Carboniferous and Devonian petroleum systems focused over and around the Mid North Sea High and northwards to the Orcadian Basin/East Shetland Platform. In the wider Irish Sea area, the focus was the Carboniferous play.Coinciding with the release by NSTA of the UK Government seismic across and around the Mid North Sea High frontier area, project results have been delivered digitally to project sponsors. They include seismic, well and gravity interpretations along with burial/uplift/maturity modelling, source rock geochemistry studies and palaeographic reconstructions to inform the location of prospective Carboniferous and Devonian plays. Onshore data and knowledge has been incorporated.The results were published under the Open Government License in March 2017 and are loaded to the BGS Offshore GeoIndex. Users should note that:These outputs are at a regional scale, created for project specific purposes and so should be used appropriately.They are not BGS corporate products, but peer-reviewed project outputs.
