METHOD FOR DETERMINING THE NATURE OF SUBTERRANEAN RESERVOIRS

METHOD FOR DETERMINING THE NATURE OF SUBTERRANEAN RESERVOIRS

A system for detecting a subterranean reservoir or determining the nature of a subterranean reservoir (35) whose position and geometry is known from previous seismic surveys. An electromagnetic field (42,43) is applied by a transmitter (37) on the seabed (33) and detected by antenna (38) also on the...

Zusammenfassung:A system for detecting a subterranean reservoir or determining the nature of a subterranean reservoir (35) whose position and geometry is known from previous seismic surveys. An electromagnetic field (42,43) is applied by a transmitter (37) on the seabed (33) and detected by antenna (38) also on the seabed (33). A refracted wave component (43,43c) is sought in the wave field response, to determine the nature of any reservoir present.
