Confined Fluid Phase Behavior and Co2 Sequestration in Shale Reservoirs

Yueliang Liu PhD is an assistant professor at the China University of Petroleum. He earned his PhD-degree in petroleum engineering at the University of Alberta. His research interests include phase behavior of fluids confined in nanopores, phase behavior of confined fluids in porous media, adsorption behavior of hydrocarbon and non-hydrocarbons in organic-rich or mineral pores, and CO2 enhanced oil/gas recovery. Liu has authored or coauthored more than 50 technical papers. He has applied for 5 invention patents. He is a member of the Editorial Board for the Journal of Petroleum Science. Liu is a member of Society of Petroleum Engineers. 1. Introduction 2.
