Participants in the Core Workshop are thanked for their enthusiasm and questions, and we hope this may help some of them, and others, to create similar stories to that of Spirit's successful development of the Chestnut Field. Jamie Bowie's skills with image enhancement and the preparation of core images was instrumental in making core images practical for publication. Reviewers Davide Duranti and Angela Melvin, and editor John Colleran are thanked for their insight and suggestions.136351752engQE GeologyQEConference item10.1144/egc1-2024-8
