Broadband electrical characterization of foam used for remediation of hydrocarbon-polluted aquifers – BBFOAM

The BBFOAM project aims to establish the founding knowledge for electrical monitoring of foams in subsurface. It will open new monitoring technics in the use of foams for aquifer remediation. Because of their unique properties (density, viscosity, interfacial tension, capillarity), foams are intuited to present rich broadband electrical responses and polarization signatures that could be distinguished from the soil electrical signature. The project will fill the lack of data and understanding of broadband electrical response of foams in porous media, from mHz to GHz, by combining a systematic laboratory exploration with the development of new elementary models. Through BBFOAM project, the scientific coordinator brings together a strong multidisciplinary team including geophysicists, experts in flow and transport in porous media and specialists of remediation processes that will push forward the use of electrical environmental monitoring through future collaborations.
