3D Modelling

The ability to visualise the Earth as a 3D volume is helping to reduce risk and the cost of discovery within earth exploration. Geosoft provides solutions for 3D modelling of gravity and magnetic data and its integration with geologic, seismic and other data to further understanding of subsurface structures.

Advanced 3D Modelling of Gravity and Magnetics

Deeper earth modelling techniques are useful in both early and advanced stages of exploration programs, helping to improve the accuracy of interpretations and exploratory drilling. Geosoft provides advanced capabilities for 3D modelling of gravity and magnetic data, enabling geoscientists to generate interpretations and easily share them across their seismic or Esri ArcGIS systems, so that other team members can work with them and continue to add value.

We help to solve these earth modelling challenges:

  • Integrated processing, mapping and analysis capabilities for multidisciplinary data within one dynamic, 3D environment.
  • Interactive 2D and 3D modelling, and interpretation, of gravity and magnetics to characterise complicated three dimensional subsurface structures of any size or scale.
  • Ability to integrate seismic, well, and geology data with observed gravity and magnetic measurements within geologic models of the subsurface.

Geosoft gravity and magnetic modelling solutions are used within the exploration programs of the world’s largest and most successful energy companies. New Geosoft modelling technology, scheduled for release in November, will provide 3D geophysical inversion capabilities as an online service accessible within Geosoft’s Oasis montaj earth mapping platform.

Integrated Platform for Earth Exploration

Oasis montaj

Oasis montaj is ideally suited for today's multidisciplinary and collaborative exploration. Access to data and a powerful set of mapping and analysis tools is provided within one dynamic, 3D environment. More than 20 extensions are available to conduct specialised geophysical processing and analysis within Oasis montaj.
