Core photographs

Core sample

All BGS core samples are being photographed as high resolution colour images (7216 x 5412 pixels, i.e. 200 dpi at 100% size for a 1 metre x 0.6 metre core tray) commencing with the UKCS (hydrocarbon) well cores, transferred from Gilmerton to Keyworth.

They may be accessed through thumbnail links from the results: details pages of the UKCS (offshore) hydrocarbon wells database.
