Abstract: The shale oil developments have more than doubled US oil production, but the oil recovery due to depressurization is typically less than 10% of the oil in place. In recent years, the Huff‑n‑Puff techniques have been tested in shale and tight reservoirs to enhance oil recovery. In these operations, CO₂, hydrocarbon (HC) gases or liquids are used. Several parameters affect the efficiency of the process: composition of gas, huff pressure, soaking time, puff pressure, depressurization rate and reservoir heterogeneity. Laboratory studies have been conducted to understand the effects of these parameters, but mostly with dead oils. We have developed a workflow that generates live oil in cores in situ that is compatible with our NMR analysis. The goal of this work is to study the effect of key parameters in the huff-n-puff process in shale cores and identify the underlying mechanisms.
Biography: Kishore Mohanty is the W.A. (Monty) Moncrief Centennial Chair Professor in Petroleum Engineering in the Hildebrand Department of Petroleum & Geosystems Engineering at the University of Texas at Austin. His research interests are in EOR, carbon capture and storage, hydrogen generation, and nanotechnology. He received his BS from IIT, Kanpur and PhD from University of Minnesota, both in chemical engineering. He worked at ARCO Oil & Gas Company R&D from 1981-1991 before joining the faculty at the University of Houston where he worked for 17 years. He joined UT PGE in 2009 and was the director of the Center for Petroleum & Geosystems Engineering, 2013-2019. He has won several awards from the Society of Petroleum Engineers including the John Franklin Karll award in 2022, SPE Distinguished Achievement Award for Petroleum Engineering Faculty, 2016 and AIME/SPE Anthony F. Lucas Technical Leadership Gold Medal, 2013.
