North Sea Core CIC is an initiative set up in November 2018 in response to the release of core material by energy companies through the relinquishment, abandonment and decommissioning of fields on the UK Continental Shelf. It is recognised that core material provides an incredible resource for understanding the subsurface and it is invaluable to geologists. Rather than seeing this important part of our offshore geoheritage fall into disuse or be discarded, we collect, transform and upcycle core material for use by the geological and wider scientific community.

All core is donated from company samples, not from material held in the British Geological Survey collection. We provide core for education and science outreach, with considerations made for those facing financial hardship. We also supply to individuals and commercial organisations. For more information please check our Core Material or Contact Us.

North Sea Core CIC remains a largely volunteer run initiative and most work is undertaken in the free time of our team. This may result in a delay in messages or providing material. Please note any views expressed are our own and not those of employers, societies we may be affiliated with, sponsors or donating companies.

The Rhynie Chert is a Early Devonian sedimentary deposit from NE Scotland. It contains a unique record of early life preserved by hydrothermal fluids and we have a selection of blocks available for academic and research purposes. If you are interested, get in touch!


Our goal is to make geoscience accessible and available to everyone through through physical and digital core material. So far North Sea Core CIC has distributed material for education, training and display across the world.
