On June 15, 2025, the DDE Petroleum Geology Knowledge System Review Discussion was successfully held at the Xinyang Room of Fairmont Yangcheng Lake, with simultaneous online participation via Zoom. This significant event brought together leading experts in geology, data science, and energy research to discuss the development and application of the Petroleum Geology Knowledge System, a key initiative under the Deep-time Digital Earth (DDE) program.

The meeting was chaired by Dr. Zhiqiang Feng, co-leader of the Energy Working Group, and aligned with the DDE’s mission to harmonize global earth evolution data and share global geoscience knowledge. As the global energy transition progresses, the creation of a comprehensive knowledge system for petroleum geology is crucial to advancing resource exploration and management, as well as promoting sustainable energy practices.

The session opened with remarks from Harvey Thorleifson, DDE GC President, and Qiuming Cheng, DDE EC Chair, who stressed the importance of collaboration in achieving the DDE’s mission and transforming geological data into actionable knowledge. Dr. Zhiqiang Feng introduced the meeting’s objectives and the challenges of constructing a unified petroleum geology knowledge system. Presentations followed, with Ting Yu discussing the construction and use of knowledge graphs to enhance data usability and support various scientific discovery, Ting Jiang and Xianming Tang demonstrating the platform’s data integration and visualization capabilities, and Dr. Guoping Bai highlighting the human-machine interaction construction process of the Petrolem Geology Knowledge System. In the discussion session, moderated by Dr. Feng, participants explored challenges in data integration, the application of AI in multi-discipline collaboration, and the need for user-friendly systems. The event concluded with summary remarks from Harvey Thorleifson, who praised the contributions of attendees and emphasized the critical role of innovation and collaboration in advancing global geoscience efforts. He looks forward to Zhejiang Lab contributing more to the DDE Energy Working Group.

This review discussion marked a significant step forward in the development of the Petroleum Geology Knowledge System. It underscored the importance of international collaboration and the transformative potential of knowledge graph technologies in addressing the challenges of the energy sector. The success of this meeting reflects the DDE’s ongoing commitment to uniting global geoscience knowledge and fostering innovation for a sustainable future.
