VOXI Earth Modelling

VOXI is a geophysical inversion service that enables forward modelling and inversion of geophysical responses in three dimensions within Oasis montaj. When provided with an observed geophysical dataset along with parameter controls and constraints, VOXI calculates the distribution of physical properties in the subsurface that best explain the observed data.

VOXI Earth Modelling delivers a solution for large, multi-parameter geophysical inversion workflows. It supports all stages of exploration and is suitable for projects of any size. Cloud-powered VOXI offers the speed and scalability required for time-sensitive mineral prospecting and target delineation. On-demand service options are available for individual users, projects, and teams—all with global, online technical support.

Working in Oasis montaj requires a project file (*.gpf). A project encompasses all items in your workspace, including:

• Data files such as databases, grids, maps, voxels, geosurfaces, and 3D views

• Visualization tools like histograms and scatter plots

• Project settings, including the menus currently displayed

This structure ensures that your entire working environment is saved and easily restored.

To begin working with VOXI, we recommend opening a new project and then loading the corresponding menus.

Open a New Project

1. On the Project menu select New. The New Project dialog will open.

   You can also select Create new project from the startup dialog that appears when you launch Oasis montaj.

2. In the New Project dialog, specify the name and location for your new project file (*.gpf), then click Save.

3. The new project will open, enabling the main menus, toolbar icons, and the Project Explorer. These visual indicators confirm that the system is ready for use.

Load the Menus

1. On the Project menu, select Manage Menus, or click the Manage Menus icon on the Project Explorer toolbar. The Manage Menus dialog will appear.

2. In Base Menus, expand the Interpretation node, select VOXI under Modelling Tools, and click OK. The menus related to the modelling tool will now appear on the main menu bar.

The menu system is designed to provide quick access to a variety of tools and guide you through the primary interpretation and modelling workflows.

Accessing Help

Once the VOXI menu is loaded, click the Help button in any dialog opened from the menu items:

• The reference topic for the current dialog will be displayed.

• Use the Help Topics tab to navigate to other topics of interest.

• Use the Search tab to find specific topics by entering keywords.
