Xuhai Tang
Professor at Wuhan University
_______

Prof. Tang obtained PhD degree from Imperial College London, and has been a research assistant at Princeton University. He is a member of the Editorial Board of the International Journal of Rock Mechanics and Mining Sciences. His group developed the AiFrac-TOUGH simulator and microscale rock mechanics experiment (micro-RME) system, in order to investigate the fracturing of geological media induced by Hydraulic-Mechanical-Thermal (H-M-T) coupling process at multiple scales. With micro-RME system, the micro-cracking and mechanical property evolution of rock-forming minerals during HMT process are able to be understood. The AiFrac-TOUGH is developed for modelling the three-dimensional fracturing, which contributes to smarter unconventional petroleum production and thermal energy exploitation, while reducing environmental impacts and contributing towards safer field operations.
