About this Release

Oasis montaj 8.0.1 is a scheduled software upgrade available to all maintained customers. This release includes a number of new workflow improvements and enhancements for Oasis montaj and extensions.

How to update

Online installs for each product are available through the Check for updates option within the software and from the download link at the top of this page. If you are using the Oasis montaj Educational version you can update through the software or contact your local Geosoft support team for an download file.

System Requirements

Oasis montaj 8.0.1 runs on Windows 8 (32 and 64 bit), Windows 7 (recommended) (32 and 64 bit) , Windows XP SP3 (32 bit), or Windows Vista (32 and 64 bit) operating systems. See detailed System Requirements

New Capabilities

Ease of Use

Convert between Geosoft and GOCAD grids

You can now convert between Geosoft and GOCAD 32-bit grids, making it easier to transfer data between software platforms.

Default colour fill pattern for rock code file

Now when you import lithology data, default colours are automatically assigned. This enables you to visualize the results right away and makes it easy to generate colours and patterns and build a rock code file.

Workflow Improvements

Convert between Velocity and Density in voxels

In a single step, you can now convert velocity cubes (voxels) directly to density, or density cube to velocity using one of several published velocity/density relationships. This new simplified workflow elminiates the steps of having to dump the voxel to a database, convert it, and then regenerate the voxel.

This tool complements the existing conversion tool for database channels, implementing the same velocity/density relationships. Velocity cubes, often as GOCAD voxet or 3D SEG-Y files, are a common exchange format for 3D seismic reflection information. A density cube may be used in GM-SYS 3D or VOXI. A density cube that is the result of modeling or inversion may be converted back to velocity for use in reprocessing seismic reflection data.

Set colour, size and symbols in the scatter plot tool

In the scatter plot tool, you can now define the colour, the size and the symbol independently. This feature was previously only available in the Geosoft extensions for ArcGIS, this update makes the scatter plot tool options the same in all Geosoft software applications and extensions.

3D Visualization

Draw vectors along a 3D drillhole paths

Using this new feature, you can draw vectors representing three component geophysical data along a 3D path such as a drillhole trace. Vector plots are very useful for visualizing interpretating three component magnetic and electomagnetic fields from borehole surveys. The colour and size of the vectors in the 3D viewer to indicate the amplitude and the direction of the surveyed geophysical field.
 

 

Orthographic 3D view added to the 3D viewer

In the 3D viewer you can now view your models in an Orthographic 3D view. When the human eye looks at a scene, objects in the distance appear smaller than objects close by. Orthographic projection ignores this effect and allows you to create drawings that are to scale.

You can toggle between between Perspective Orthogonal icon and Orthographic Orthogonal icon views by clicking the new icons on the toolbar. The options are also available under Tools & Settings > Rendering Settings.

Oasis montaj Extensions

GM-SYS 3D

Export a layer property distribution as a grid

You can now use an existing part of the model to define the density/depth relationship for the model, which saves you some steps and avoids duplication.

Select a model layer as a density depth table reference surface

You can now select an existing model layer as a density depth table reference surface, instead of having to browse for an original source grid in the model or workspace.

Gravity and Terrain Correction

More options for handling repeated gravity values

When there are multiple gravity readings at a station, often it is preferable to select an actual value from among the repeats, such as the median value. To meet this requirement, you now have ability to set the single replacement value to be the Median, Minimum or Maximum of the coincident readings. The existing Mean option is also still available.

Ouput the Bullard curvature correction as a channel

In the gravity workflow, the Bullard B curvature correction and the simple Bouguer correction are will now output as separate channels. In addition, the earth density is now properly interpreted. You can inspect the magnitude of each correction in its own right.

Induced Polarization

Induced Polarisation quality control toggles

Performing quality control on a large induced polarisation (IP) database can require a lot of editing. To help make editing easier and save you valuable time, we've added these new shortcut toggles: R = Reject, A = Accept, F = Flag, N = Next transmitter, S = Next Sample
