At 13:00 on May 31, 2022 Beijing time, under the coordination of the Secretariat of the Worldwide Energy University Network, an academic salon jointly organized by the International Multiphase Flow Technology Forum (IMFTF) and the Chinese Society of Particuology was held at the online conference platform. The event invited Professor Kristian Jessen from the University of Southern California to give a special academic report.
Professor Kristian Jessen won the International Society of Petroleum Engineering (SPE) Distinguished Member Award and the SPE Regional Health, Safety and Environment Award in 2021. He is currently working at the University of Southern California, Mork Family Department of Chemical Engineering and Materials Science, dedicated to the research on theoretical knowledge of improving petroleum and natural gas recovery. The meeting was chaired by Professor Wei Yan of Technical University of Denmark. Professor Kristian Jessen's wonderful report has attracted more than 25,000 professional viewers in related fields of live broadcast platforms such as Bilibili website, video account, Weibo, Kuaishou, Zhihu, Baidu, YouTube, Facebook, and official website (Scientific Research Cloud).
After a brief chat, Professor Wei Yan first introduced Professor Kristian Jessen to everyone, emphasizing his contributions in the fields of flow and transport in porous media; the phase behavior and transport characteristics of non-ideal mixtures; the CO2 sequestration in depleted oil and gas reservoirs, salt aquifers and coal seams; analysis and accurate solution of hyperbolic higher-order conservation equations, etc. And then Professor Wei Yan warmly invited Professor Kristian Jessen to start this thematic report entitled: Investigation of Mass Transfer and Sorption in Shale under Variable Net Stress.
After expressing his gratitude, Professor Kristian Jessen started his presentation. Before formally introducing his work, Professor Kristian Jessen introduced the current research background in the field of unconventional oil and gas reservoirs, enhanced oil and gas recovery, gas storage models and simulations. After that, Prof. Kristian Jessen introduced his work in detail from the research objectives, model simplification, sorption kinetics, Mass transfer experiments, and sorption and mass transfer of mixed gas. After raising the research objectives for the laboratory and the field respectively, Professor Kristian Jessen introduced the experimental research approach of sorption and pressure-decay at gas loading for 3.5-inch shale samples, and introduced the experimental results of sorption isotherms and kinetics in detail. And the core characteristics experiments of 18.03 × 8.89 × 2.54cm samples using helium and argon gas, detailed analysis of the full-diameter core characteristics from the Marcellus block. After that, combined with the experimental results, Professor Kristian Jessen gave a novel integral formulation for mass transfer/storage in multi-porosity shale systems, and successfully predicted the methane production behavior of the full-scale core in the laboratory. Finally, Professor Kristian Jessen gave relevant research conclusions and work prospects.
The whole report is simple and rich in content, and the online students have a comprehensive understanding of the work content of Professor Kristian Jessen's research on mass transfer and sorption of shale under variable net stress conditions. Before I knew it, the 60-minute report was over, and then we entered the question-and-answer session. The enthusiastic audience asked questions, and Professor Kristian Jessen answered them in detail. The report ended successfully in 30 minutes of lively discussion.
As one of the international academic organizations under the framework of the Worldwide Energy University Network, the International Multiphase Flow Technology Forum was established on January 10, 2020. Up to now, the members of the IMFTF committee come from 13 famous universities in 7 countries around the world. The forum aims to gather experts in the field of multiphase flow from all over the world to discuss the development of multiphase flow technology in the industrial field, to jointly carry out scientific research in the face of technical problems, and to clarify the future development direction of multiphase flow technology for young scholars.
