MORE THAN 40 YEARS OF EXPERIENCE IN AIRBORNE GEOPHYSICAL SURVEYS

WITHIN RUSSIA AND WORLWIDE

Magnetics

Aerogeophysica has unique technologies for high resolution magnetometer survey on different scales, as well as data processing and interpretation means. Airborne magnetics, combined with another methods (gravity, EM, spectrometry) can be apply for the wide range of exploration tasks:

Ore exploration;

Hydrocarbon exploration;

Monitoring of territories and geological processes;

Research into deep geological structures and geological mapping;

The survey data are obtained with high-sensitivity cesium magnetometer AEROMASTER 100 (designed by Aerogeophysica) employing sensor CS-3 (Scintrex - Canada).

Obtained data are processed and interpreted with both original Aerogeophysica-designed software and available, known commercial means.
