David A. Wood has more than forty years of international gas, oil, and broader energy experience since gaining his Ph.D. in geosciences from Imperial College London in the 1970s. His expertise covers multiple fields including subsurface geoscience and engineering relating to oil and gas exploration and production, energy supply chain technologies, and efficiencies. For the past two decades, David has worked as an independent international consultant, researcher, training provider, and expert witness. He has published an extensive body of work on geoscience, engineering, energy, and machine learning topics. He currently consults and conducts research on a variety of technical and commercial aspects of energy and environmental issues through his consultancy, DWA Energy Limited. He has extensive editorial experience as a founding editor of Elsevier’s Journal of Natural Gas Science & Engineering in 2008/9 then serving as Editor-in-Chief from 2013 to 2016. He is currently Co-Editor-in-Chief of Advances in Geo-Energy Research. Jianchao Cai received his B.Sc in Physics from Henan Normal University and MSc and Ph.D in Condensed Matter Physics from Huazhong University of Science and Technology. He is currently a professor at the Institute of Geophysics and Geomatics at the China University of Geosciences (Wuhan). Meanwhile, he serves as Associate Editor or Editorial member for several journals including Journal of Natural Gas Science & Engineering, International Journal of Oil, Gas and Coal Technology, Fractals. He has published more than 130 journal articles, two books, and numerous book chapters.
