A system for detecting a subterranean reservoir or determining the nature of a subterranean reservoir 12 whose position and geometry is known from previous seismic surveys. An electromagnetic field 24, 25, 26, 27 is applied by a transmitter 18 on the seabed 14 and detected by antenna 21, 22, 23 also on the seabed 14. A refracted wave component is sought in the wave field response, to determine the nature of any reservoir present.
