If materials could speak, what stories would they tell about the microscopic world? On the morning of April 13, driven by curiosity and the desire to find answers, researchers and engineers from across the country arrived early at the registration desk. Today, as the final certificate was handed to a participant, the First Low-Field Nuclear Magnetic Resonance (LF-NMR) Application Training Course of 2026, organized by Niumag Analysis, came to a successful close. The Beginning: A Thrilling Intellectual Challenge After a brief opening ceremony, technical terms such as “transverse relaxation time” and “longitudinal relaxation time” filled the room. Many participants initially furrowed their brows. For many, low-field nuclear magnetic resonance (LF-NMR) remains an enigmatic black box—they know it is powerful, but when it comes to hands-on operation, there is often a hesitation, as if wielding a sharp tool for the first time. To bridge this gap, the training was carefully structured into five core modules: from the fundamental principles and hardware architecture of LF-NMR, to application methods addressing key pain points in petroleum energy, geotechnical engineering, and materials science, and further to comprehensive demonstrations of general and specialized software operations. The intensive theoretical sessions on the first day were not merely challenging—they were designed by the instructors to lay a solid foundation for demystifying the “magic” that followed. Unlocking the Magic: Hands-On Experience in the Laboratory The most exciting part of the training did not take place in the classroom, but at the laboratory bench. During the course, Niumag not only provided access to multiple core magnetic resonance imaging (MRI) and analytical instruments, but also prepared a variety of real experimental materials for the hands-on sessions. When participants placed genuine core samples and polymer materials into the NMR probes and operated specialized software for core analysis, oil/water content determination, and crosslink density measurement, the veil of mystery was completely lifted. Here, “real materials, real operation, real experience” was more than a slogan—it was the foundation that ensured participants could seamlessly transfer their acquired skills to daily research. Low-field NMR truly became a “microscopic stethoscope” in their hands. Guidance from Masters: A Collaborative Arena with No Spectators Two types of guides supported this journey of discovery. On one side, we were honored to invite Professor Xinmin Ge from the School of Petroleum Engineering at China University of Petroleum (East China). As a recipient of the Outstanding Youth Fund of Shandong Province and an expert deeply engaged in logging methods and petrophysics, Professor Ge presented complex theories in an accessible manner, helping to clear the fog on the participants‘ research paths. On the other side, Niumag’s experienced team of application engineers provided continuous on-site guidance. Rather than lecturing on abstract theories, they focused on practical details—whether the mouse clicks were correct and whether the parameters were set accurately. Thanks to the small-class teaching format, there were no passive spectators. The “Q&A and case study” sessions each afternoon were often even more lively than the lectures. Some participants brought real-world “difficult problems” from their own projects to the stage for live consultation with the instructors. In the laboratory, “How did you handle the pore size distribution of this core sample?” became one of the most frequently heard questions. Strangers in the field quickly became teammates working side by side. “I used to think low-field NMR was beyond reach. Now I feel it’s like an old friend in my laboratory. I’ve gained knowledge and found answers to my questions,” one participant remarked. Conclusion: The Story Has Just Begun Although the First Low-Field Nuclear Magnetic Resonance (LF-NMR) Application Training Course of 2026 has concluded, these participants—now equipped with new skills and insights—will return to their respective laboratories, ready to tackle real scientific challenges with their newly acquired “perspective” into the microscopic world. The spark of knowledge has been ignited, and the story has only just begun. We look forward to meeting more of you—passionate explorers—at the crossroads of the microscopic world in Niumag‘s future training courses.

At the 2nd International Frontiers Forum on Earth Energy (Zhengzhou, April 10–13, 2026), Niumag Analysis showcased its low-field nuclear magnetic resonance (LF-NMR) technology as a green, fast, and non-destructive solution for earth energy exploration. The technology demonstrates significant value in unconventional energy (e.g., methane adsorption/desorption, hydrate dynamics, supercritical CO₂ fracturing evaluation), reservoir property analysis (porosity, pore size distribution, fluid saturation, permeability, wettability), oil/gas development (fracture characterization, enhanced oil recovery monitoring, reservoir damage assessment), and low-carbon applications (CCUS/CCS in-situ simulation). By enabling efficient and intelligent geological evaluation, LF-NMR supports the global transition toward sustainable energy development and interdisciplinary innovation.
