Title (EN) GEOPHYSICAL PROSPECTING USING ROTATIONALLY INVARIANT PARAMETERS OF NATURAL ELECTROMAGNETIC FIELDS
(FR) PROSPECTION GÉOPHYSIQUE UTILISANT LES PARAMÈTRES INVARIANTS ROTATIFS DES CHAMPS ÉLECTROMAGNÉTIQUES NATURELS
Abstract:
(EN) A geophysical survey method and system that comprises: measuring along multiple axes at multiple locations within a survey area magnetic field components of a low frequency magnetic field resulting from naturally occurring electromagnetic sources using a first sensor system; measuring along multiple axes magnetic field components of a low frequency magnetic field resulting from naturally occurring electromagnetic sources using a second sensor system; and receiving information about the magnetic field components measured by the first sensor system and the second sensor system and in dependence thereon computing parameters from the received information that are independent of rotation of the first sensor system or the second sensor system about any axis thereof.
(FR) L'invention concerne un procédé et un système d'étude géophysique comprenant : la mesure le long de plusieurs axes à des emplacements multiples à l'intérieur d'une zone d'étude de composants de champ magnétique d'un champ magnétique basse fréquence résultant de sources électromagnétiques naturelles en utilisant un premier système de détection; la mesure le long de plusieurs axes de composants de champ magnétique d'un champ magnétique basse fréquence résultant de sources électromagnétiques naturelles en utilisant un second système de détection; et la réception d'informations sur les composants de champ magnétique mesurés par le premier système de détection et le second système de détection et en conséquence les paramètres de calcul provenant des informations reçues qui sont indépendants de la rotation du premier système de détection ou du second système de détection sur tout axe de celui-ci.
