Help using the mobile borehole record viewer


Welcome to the mobile borehole scans viewer created by the British Geological Survey. This application offers direct, online access to the National Geoscience Data Centre collection of onshore boreholes, shafts and well records.

What is a borehole record?

A record of boreholes, shafts and wells from all forms of drilling and site investigation work. Boreholes range from one metre to several thousand metres deep. Borehole records are produced from a geologist's or surveyor's observations of the rock core extracted from the ground. It typically includes locality, lithological descriptions with depth and thickness. For further information on boreholes, click here.


Borehole records are displayed as coloured circles, each with their own unique borehole reference number. The colour of the borehole icon identifies how deep it was drilled. The map legend can be found by pressing the Layers button. Where boreholes are coloured black, we are unable to provide a direct link to the associated scanned borehole record. We may still be able to provide you with a borehole record via our GeoRecords Plus+ service.
