GM-SYS Profile Modelling

The GM-SYS Profile modelling tool includes an interactive gravity and magnetic profile modelling program that allows you to integrate seismic, well, and geological data with observed gravity and magnetic measurements. Use it to build geologic models and assess their accuracy by comparing the model’s gravity and magnetic responses with observed measurements. 

Key Features:

  • Create GM-SYS Profile models

  • Define and edit geologic horizons and blocks

  • Perform forward and inverse modelling of potential field data

  • Generate models directly from map profiles

  • Import and work with SEG-Y seismic data

  • Convert time-based models to depth-based models

  • Integrate well data for improved accuracy

  • Build comprehensive geologic models

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 GM-SYS Profile, 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 GM-SYS Profile 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 to guide you through the primary interpretation and modelling workflows.

To automatically load these menus in future projects, specify them in the Default menus field of the General Settings dialog.

Accessing Help

Once the GM-SYS Profile menus are loaded, click the Help button in any dialog opened from these 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.

*GM-SYS Profile topics are accessed through GM-SYS Modelling Help, separate from the Oasis montaj Help system.
