Modeling of Gas Transport in Shale Matrix from Nanoscale to Reservoir Scale

Keliu Wu is currently an associate professor at the China University of Petroleum-Beijing. Previously, he was a post-doctoral-degree fellow and a research associate at the University of Calgary. Wu’s research interests are microscale and nanoscale fluid transport, scaling up of fluid transport in heterogeneous porous media, and numerical modeling and simulation of coupled flow and geomechanics processes. He also focuses on carbon dioxide sequestration in shale-oil/gas reservoirs and tight oil/gas reservoirs. He holds a PhD degree in petroleum engineering from the China University of Petroleum-Beijing Jinze Xu holds a Ph. D degree from University of Calgary. He has published more than 30 peer-review papers on shale gas and heavy oil. He is the editorial board member for Energy Reports, Geofluids, International Journal of Oil, Gas and Coal Technology, and Journal of Geophysics and Engineering. He was awarded an “Outstanding Contribution in Reviewing” by Elsevier in 2018, a “Top Peer Reviewer” by Web of Science and Publons in 2019, a “Best Reviewer” by International Conference on Energy Engineering and Environmental Protection in 2020. Zhangxin Chen is a professor in the Department of Chemical and Petroleum Engineering and the Director of the Foundation CMG/Frank and Sarah Meyer Collaboration Centre at the University of Calgary. He is a fellow of the Canadian Academy of Engineering. Dr. Chen has the distinction of holding two chairs: the Natural Sciences and Engineering Research Council of Canada/Energi Simulation Senior Research Chair in Reservoir Simulation and the Alberta Innovates Technology Futures (AITF, formerly iCORE) Industrial Chair in Reservoir Modeling. Dr. Chen holds a PhD degree from Purdue University.
