Offshore gravity and magnetic explorations

Gravity and magnetic surveys are the components of the set of geophysical methods applied in hydrocarbon explorations. The methods provide the additional information about geological structure of the surveyed area.

Scopes of work in 2017-2019

  • 34,167
    linear km
    Offshore gravity surveys
  • 44,194
    linear km
    Shipboard magnetometer surveys

Applicable magnetometric equipment
  • Shipboard magnetometer-gradiometer SeaSPY 2;
  • Shipboard magnetometer SeaSPY;
  • Shipboard gravimeter Chekan-AM (CSRI Elektropribor);

Gravimetric method of explorations is based on a study of the field of gravity at the surface of the Earth. The measurements of this field elements allow to determine the distribution in the earth's crust of masses of different densities and, consequently, the depth structure of the studied areas.


Applicable software
  • Package «Oasis montaj» (Geosoft)
  • Package «DataPro» (Fugro-LCT)
  • Package «GridInPro» (Fugro-LCT)

The magnetic method is based on the study of the magnetic field features associated with various magnetic properties of the rocks. The change in magnetic properties and different forms of bedding of the magnetic rocks produce the various magnetic anomalies, i.e. deviation of geomagnetic field intensity in a specific region from its normal values
