A new open dataset to benefit onshore geoscience research
Data from deep onshore hydrocarbon wells is being released on an open access basis to help meet the UK’s net zero targets.
15/06/2023
The North Sea Transition Authority (NSTA) has authorised the release of all the well data for onshore hydrocarbon boreholes held by BGS in the National Geoscience Data Centre (NGDC). Unlike borehole data from the North Sea, which has been available free of charge for some time, the data relating to these onshore boreholes was previously only available via data release agents. It is now available free of charge to industry, academics and the public via the BGS Geoindex, providing a new, free resource that will add to the knowledge necessary to meet net zero objectives.
Why is the data significant?
Few boreholes have been drilled to these depths (over 1 km) onshore in the UK and are almost exclusively a consequence of oil, gas or coal exploration. The oil and gas wells deeply penetrate the crust under the UK mainland and are geographically widespread across the UK.
Unlike coal wells, the oil and gas drilling data is better structured and better conforms to global standards of deep geological and deep geophysical data collection.
Most of the direct knowledge and samples that BGS has access to about the deep geology of the UK are based upon this data.
Why is the data being released?
Data from these deep hydrocarbon wells forms the best dataset to understand the geology of the deep UK subsurface. Widening access to the dataset could enhance the knowledge needed to meet net zero objectives:
- assessing the suitability of UK rocks for extraction of geothermal heat
- storing surplus energy from renewables and waste materials such as carbon dioxide
- identifying potential new mineral resources.
The data has been provided to BGS under regulation PON 9B, which sets out the records and samples requirements for onshore surveys and wells licensed by the NSTA. The data was previously held for BGS internal science use only, so this release widens the community of scientists who can access this important dataset. It includes the data for all boreholes that have been released (four years post-drilling) and for which BGS holds original geophysical data.

Data is being released using an Open Government Licence, which allows users to copy, publish, distribute and transmit the information, adapt the information and exploit the information commercially and non-commercially, provided that they acknowledge the source of the information.
The NSTA has collected data from more than 2200 onshore wells drilled in the search for oil and gas. Historically, half of that data were released through the British Geological Survey (BGS) with the rest provided by Data Release Agents on behalf of the NSTA. The new arrangement with the BGS means that all onshore hydrocarbon well data will be available from BGS. This free access to the unique onshore data will support the investment and innovation necessary to enable the ongoing energy transition.

BGS GeoIndex
The data is available via the BGS GeoIndex on a layer called ‘Onshore UK hydrocarbon well data’ and currently includes over 60 000 logs from 1200 wells and the number is still increasing. All related records in the BGS Borehole Index (which contains summary borehole metadata) have also been marked as open, releasing over 2000 records that were previously marked as confidential in the index.
