Shimin Liu, professor of energy and mineral engineering and the Thomas V. and Jean C. Falkie Mining Engineering Faculty Fellow at Penn State, and co-author Guijie Sang, who recently earned his doctorate in energy and mineral engineering from Penn State, received the Rossiter W. Raymond Memorial award from the Society of Petroleum Engineering (SPE) and the American Institute of Mining, Metallurgical, and Petroleum Engineers (AIME) for the best paper published in AIME's fields. The paper, “Carbonate Caprock–Brine–Carbon Dioxide Interaction: Alteration of Hydromechanical Properties and Implications on Carbon Dioxide Leakage,” focuses on the long-term integrity of carbon caprock, which is used to secure, seal and trap CO2 in subsurface formations as part of geological carbon sequestration for carbon management.
