Digital Rock Model and Pore-level Network Modelling

Topic of lecture: Digital Rock Model and Pore-level Network Modelling

Lecturer: Jiang Zeyun, Heriot-Watt University, U.K.

Time of Lecture: Oct. 23th, 2017 (Mon), 4:20 – 6:20 p.m.

Location of Lecture: Mingli Hall A101

Abstract of Lecture:

It is widely recognized that rock petrophysical properties and flow/transport behaviors are dominated by pore morphology (geometry and connectivity) and wettability distribution. Over the last few decades X-ray micro- or nan- computed tomography (CT) makes it possible to analyze pore structure in details and more accurately, and to carry on fluid flow simulations directly or indirectly from the resultant 3D images. For complicated rocks such as carbonate and shale, however, many structural features (e.g. multi-scale pores and various pore shapes) that are closely related to two or three-phase flow are unable to be revealed by CT scans only because of the trade-off between sample size and resolution. Therefore realistic models and fast and accurate multi-phase flow/transport simulators are highly in demand in addition to traditional core experimental analysis. In this talk, a newly developed pore architecture reconstruction will be introduced with a set of successfully reconstructed models of complex structures in rocks. And also our in-house multi-scale pore network modelling (including some numerical techniques like the Lattice-Boltzmann method if possible/necessary) will be demonstrated and discussed in the applications to carbonate and shale rocks.

Introduction of the lecturer:

Jiang Zeyun, researcher and Ph.D supervisor of Petroleum Engineering Institute of Heriot-Watt University, U.K. He was awarded his Ph.D. in petroleum engineering in Heriot-Watt University in 2008 and successively took research and teaching positions as postdoctoral researcher, assistant researcher, lecturer, and associate professor. Since 2004, he has engaged in the analysis and restructuring of pore structures, and the multi-phase flow modeling and numerical simulation of microscopic fluids in porous media. He has participated in and mentored projects funded by British EPSRC and 4 projects jointly sponsored by Petrobras, Shell, Total and BP. He has supervised and co-supervised 7 Ph.D. students. He has published nearly 50 papers at international conferences and in influential journals like Advances in Water Resources, Water Resources Research, Transport in Porous Media, Fuel, and Marine and Petroleum Geology.
