Prof. Xuhai Tang

Xuhai Tang is a Professor at Wuhan University. He holds a PhD degree from Imperial College London and was a postdoc at Princeton University. Prof. Tang developed a microscale experiment system and AiFrac simulator to study the fundamental mechanical behaviour of

Earth and planetary geological materials. The microscale experiment system is able to test the mechanical property of minerals, which is especially useful for non-standard rock/soil samples including fracture filling materials and Mars/lunar samples. The AiFrac simulator is widely applied for analysing the multiscale deformation and fracturing of geological materials induced by Hydraulic-Mechanical-Thermal-Chemical (THMC) process. Prof. Tang’s achievement contributes to smarter petroleum production, geothermal production and space exploitation. He is the editorial board member of the “International Journal of Rock Mechanics and Mining Sciences”.

Mechanical property of minerals and their impact on earth/planetary geological material

We develop an advanced system to investigate the mechanical property of minerals and their impact on earth/planetary geological materials, which combines microscale rock mechanics experiment (micro-RME) and accurate grain-based model (AGBM). The micro-RME is developed to test the physics property evolution of rock-forming minerals under hydraulic-mechanical-thermal-chemical coupling process. The AGBM is developed to solve the macroscale mechanics property of geological materials numerically, based on Micro-RME result.

This system is especially useful to test non-standard rock/soil samples, such as filling in fractures, arbitrarily-shaped cuttings, meteorite and samples of Mars/lunar rock. Additionally, this system advances our fundamental understanding the mechanical property of geological material at mineral scale.

AiFrac – the digital twin for modelling the deformation and fracturing of reservoirs

The Aifrac simulator is developed to create the digital twin of reservoirs with mechanical deformation and fracturing. In this AiFrac simulator, advanced numerical algorithms, such as extended finite element method and phase field method, are developed to model the deformation and fracturing of geomaterials induced by Hydraulic-Mechanical-Thermal-Chemical coupling process. Additionally, the combination of physical simulation and machine learning is developed to analysis the geostress redistributioin and hydraulic fracturing, according to monitoring data. This achievement contributes to smarter energy oil/gas production, geothermal production and space exploitation.
