The uses the subsurface will only increase and diversify with the continued transition of the energy industry, and therefore the management of the subsurface is a pressing issue. The GeoConnect³d project developed and tested a new methodological approach to prepare and disclose geological information in a more useful and understandable way for policy support and subsurface management. This innovative bottom-up approach introduced two concepts to increase the geological understanding of an area and are aimed at providing a coherent geological context for evaluating subsurface applications and resolving subsurface management issues. The first new concept is the structural framework as a means of joining existing models of different scale and resolution to clarify the importance of geological surfaces, such as faults, contacts, lineaments, unconformities etc., in a way that makes the geology understandable to stakeholders involved in subsurface management. The second concept is that of geomanifestations. These specific expressions of geological processes are important sources of information for improving geological understanding.
