Peng Lu, Ph. D., is a geologist at EXPEC Advanced Research Center, Saudi Aramco. He has 16 years of experience in geochemical modeling. His research interests encompass carbonate and clastic diagenesis, reservoir quality prediction, reactive transport modeling, and geological carbon storage. He is one of the developers of SUPCRTBL and SupPHREEQC and a co-author of Theory and Applications of Geochemical Modeling (in Chinese), published by Science Press in China. Dr. Lu received a Ph.D. degree from Indiana University in 2010.
Chen Zhu is a professor of Earth and Atmospheric Sciences at Indiana University, USA. He co-authored with Greg Anderson the book Environmental Application of Geochemical Modeling, published by Cambridge University Press, which has been used as a textbook around the world.
Advanced Geochemical Modeling
Geochemical modeling is a powerful tool, which has wide applications in geology, hydrogeology, environmental sciences and engineering, and petroleum geology. Recently, new databases, functions, code enhancements, and utilities associated with the computer programs Supcrtbl (Zimmer et al., 2016) and Phreeqc (Parkhurst and Appelo, 2013) have greatly expanded the applicability ranges of these modeling tools. This includes expanding speciation, solubility, reaction path modeling up to T and P of 5 kb and 1000 oC; A kinetics library of rate equations and parameters of about 100 minerals (Zhang et al., 2019).
This workshop will introduce these new tools and use examples to demonstrate these expanded geochemical modeling capabilities with examples for modeling silicate dissolution experiments, clastic and carbonate diagenesis, geothermal fluids, and geological CO2 storage.
