In this demo, we present a Virtual Reality (VR) Prototype that assists geoscientist in the task of seismic interpretation. The system renders a 3D seismic volume in a virtual reality environment where users may see semantic information and add annotations. The data integration is provided by a hybrid knowledge base that handles multimodal data like 3D models and multimedia content. The knowledge base can support other systems as well, which permits reasoning over the data. Therefore, our proposed system is intended to assist users in seismic interpretation by combining visual inspection with immersion, semantic information retrieval, and structured storage.
