Borehole data

The BGS Information Management (Geology) Project maintains the Borehole Geology database which holds geological interpretations of boreholes drilled in Great Britain; it is one of our key data sets.

The Borehole Geology database is normally used in conjunction with another database, the Single Onshore Borehole Index, which is the index to borehole records that we hold.

The interpretations stored in the Borehole Geology database are made from borehole logs that show the geology encountered at depth within each borehole. In many cases, these logs were created by the geotechnical companies responsible for drilling the holes, and supplied to the BGS.

In other cases, the logs may have been made by our own geologists, either at the time of drilling, or subsequently from core samples, many of which are held at BGS.

The Borehole Geology database is a primary source of data used to characterise the subsurface geology of Great Britain.

It is heavily used for creating 3D models, including the National Geological Model.

The database holds more than three million records, relating to more than 600 000 boreholes.

The data are stored in standardised coded formats that ensure interoperability with our other data systems.

We have a continuous rolling programme of validation and verification, to make sure the data remain fit for use in producing our products and services.
