At the invitation of researcher DENG Shouchun from IRSM, Researcher PAN Zhejun from CSIRO visits SKLGME on June 19, he delivers a speech with the topic Testing and Modeling of Shale Gas Occurrence and Flow.

PAN Zhejun introduces the organization structure of CSIRO at the beginning, he then lead to the introduction of multiple experimental equipments and their performance characteristics developed by non-traditional natural gas laboratory of CSIRO. PAN elaborates on shale gas absorption, free gas quantity test, diffusion and permeability measuring principle; he points out that all the testing results are for specific medium under special experimental condition, which is different from the storage condition of shale gas. Considering the distribution range of organic matter pore， inorganic substance pore and natural micro fissure pore; and different occurrence and flow condition of methane in different pore, PAN suggests to use triple porosity reservoir model. He has specific research on the changing characteristics of adsorption gas and free gas. After his report, PAN has further discussion with present audiences on measurement principle and method of adsorption gas, and differences between coal bed gas and shale gas.

Dr. PAN Zhejun graduated from Oklahoma State University. He is now the researcher of CSIRO, guest professor of China University of Geosciences (Beijing) and China University of Petroleum (Beijing). His research fields include occurrence and flow mechanism of gas in unconventional reservoir, unconventional natural gas production prediction, etc. Dr. PAN has published more than 80 papers since 2002, including more than 40 SCI papers, his paper was cited more than 670 times by SCI. He won Victoria Fellowship in 2008, Rock Mechanics Research Award of American Rock Mechanics Association in 2011, and Julius Outstanding Youth Award of CSIRO in 2012.
