"Geosoft is still by far the best software for generating gravity and magnetic interpretations, and products that can be easily integrated into the seismic world. I can process data, work on maps, and build the model in the same platform. I can generate something and send it knowing that in a few minutes, they can have it at their work station and on their screen."

Gravity and Magnetics
GM-SYS 3D is gravity and magnetic modelling software for surface-oriented models. Fully integrated with Oasis montaj, it allows geoscientists to model complicated three dimensional subsurface structures of any size or scale.
Powerful three dimensional insight of subsurface structures
GM-SYS 3D is 3D gravity and magnetic modelling software for surface-oriented models, developed as an extension for Geosoft Oasis montaj. The extension, which requires the Oasis montaj MAGMAP Filtering extension, allows geoscientists to model complicated three dimensional subsurface structures of any size or scale.
With GM-SYS 3D Modelling, you can:
- Create insightful 3D models by integrating gravity and magnetic, and seismic data.
- Plot 3D displays of the model in one simple step, while retaining control over each element in the 3D visualisation.
- 3D visualisations update automatically during inversion and structure editing.
- Add wells, seismic sections or volumes, or other vector or raster information to their 3D model visualisations.
- Create a well-constrained model with the inversion tools.

Recommended hardware and software requirements for GM-SYS 3D Modelling 8.1
Windows 8 (32-bit and 64-bit)
Windows 7 SP1 (32-bit and 64-bit) - Recommended.
|CPU||A Dual Core processor is recommended. An Intel Celeron processor is not recommended.|
|RAM||4-8 GB recommended, 1 GB minimum required.|
|Graphics||Nvidia Professional 256MB 3D (OpenGL 2.0) Graphics Card recommended.|
|Printer/Plotters||Any Windows® supported colour printer. Hewlett Packard® large-format ink-jet plotters are recommended.|
|Installation Permissions||When installing Oasis montaj or Target, you MUST be logged on with Administrator permissions.|
|Installation Disk Space||2 GB or more of free space on the Program Files drive is required for the installation process.|
|Data Disk Space||Data disk space depends on the volume of project data to be processed and the printer driver you are using. We recommend 500 GB to 1 TB, minimum 50 GB.|
Internet Connection: To use VOXI, we recommend a medium to high-speed internet connection (512Kbps upload and 1Mbps download or higher). The faster your internet connection, the faster you will be able to upload your modelling information to the VOXI cloud servers and download your results.
Internet Browser: To use the internet capabilities in Oasis montaj or Target, you will need to install Internet Explorer 8.0 or later. This does not mean that you have to have Internet Explorer as your default browser; Oasis montaj and Target just use the internet connection technology supplied in IE8.
The following software prerequisites are required and will be downloaded and installed if not present:
• Microsoft .NET 4
• ESRI ArcEngine 10.2
