“…The foam performance offered by a given surfactant may depend on several factors, such as surfactant type and concentration [41][42][43][44][45][46], gas composition [47][48][49][50], brine salinity [51,52], rock petrophysical properties and lithology [37][38][39]53], wettability [54,55], foam- Since review articles on foam as a liquid controlling agent in porous media, to our knowledge, have not been made before, we find it useful to present an overview of the present knowledge and state of the art. The aim of this study is to summarize the documented observations of foam water-blocking abilities from previous field experiences and laboratory studies to better indicate its advantages, challenges, and possibilities for future applications.…”

This article summarizes the state-of-the-art knowledge gained from field observations and laboratory studies regarding foam as a liquid controlling agent in porous media. Being the least explored property of foam, its effect and potential have often been overlooked or simply ignored. The aim with this review is therefore to demonstrate the abilities that foam could have to block, reduce, delay, suppress, or divert water flow in porous media. As a liquid controlling agent in porous media, foam has potential for industrial processes that involve fluid injections or fluid withdrawals in porous geological formations, such as improved/enhanced oil recovery (IOR/EOR), matrix-stimulation treatments, underground storage of CO2, hydrogen, compressed-air or natural gas withdrawal, geothermal energy, and contaminated soil-groundwater remediation processes with unwanted aquifer impacts. Improving the water utilization factor and water management in these applications might result in tremendous energic, economic, and environmental incentives that are worth pursuing. Specific focus in this review is given to the post-foam water injection, which determines the ultimate stability and water-blocking capabilities of the foam treatment. Main parameters and mechanisms that can influence foam stability against water injection/intrusion after generation and placement are assessed and discussed. Unresolved issues are highlighted, which give recommendations for further research and field-scale operations.
