CO2-Soluble Ionic Surfactants and CO2 Foams for High-Temperature and High-Salinity Sandstone Reservoirs

21.08.2015 | Zheng Xue; Krishna Panthi; Yunping Fei; Keith P. Johnston; Kishore K. Mohanty, Energy & Fuels, 2015

The sweep efficiency of CO2 enhanced oil recovery can be improved by forming viscous CO2-in-water (C/W) foams that increase the viscosity of CO2. The goal of this study is to identify CO2-soluble ionic surfactants that stabilize C/W foams at elevated temperatures up to 120 °C in the presence of a ...
