Borehole core collections

Collection of continuous borehole core, broken core, cuttings, etc. are held at Keyworth. The hydrogeological materials collection, which includes core and borehole material, is housed at Wallingford.

  • Onshore borehole material database (including hydrocarbon wells). Approximately 200 km of core, plus about 150 km of drilling represented by cuttings. Samples are held from about 15000 boreholes. Borehole names and positions may be determined from GeoIndex.
  • UKCS (offshore) hydrocarbon well samples. BGS manages the national collection of hydrocarbon well samples. The collection consists of core and cuttings for all wells drilled for hydrocarbon exploration in UK waters was transferred from the Gilmerton store, Edinburgh to Keyworth during 2011–12.
  • Offshore material: cores, vibrocores, gravity cores, grab samples, etc. There are about 12 000m of core and 15 000 seabed samples. Core positions are available on the Geo-Seas website.
  • Maritime and Coastguard Agency (MCA) Civil Hydrography Programme (CHP) seabed samples. Material from samples that are routinely collected from the seabed during Civil Hydrography Programme (CHP) Hydrographic Instruction (HI) surveys.
  • Nirex Geological Archive. The Nirex geological archive was transferred from Nirex to the British Geological Survey (BGS) during 2000/2001. The archive consists of borehole cores and samples, thin and polished sections, digital data and paper records acquired by Nirex during its investigations at Sellafield and Dounreay.

Specimens are available for study at Keyworth and a loan system is available to accredited scientists.
