An experimental setup for shallow subsurface hydrogeophysical monitoring has been installed at the Maguelone site, located along the Mediterranean lido of the Gulf of Lions near Montpellier, France. The objective of the experiment is to to test in an integrated manner a full suite of coordinated monitoring techniques, either from surface or downhole. The field spread includes the injection hole, a logging hole, downhole electrical observatories at variable distance from the injection point, a downhole hydrodynamic observatory based on a pore fluid sampling completion from WestBay (SWS), a downhole seismic observatory, plus surface electrical and seismic observatories. This coordinated set of observatories should lead to the design of integrated sensors and methods for water management in a variety of hydrogeological settings, as well as for the monitoring of gas injection in deeper reservoirs.
